There isn't currently a way to inject an internal DTD subset.

Your best bet is to either write out the DTD before the serialised document 
(easy if you serialise to UTF-8), or to parse a new empty document with the 
above internal subset and replace its content by your own XML tree, then 
serialise that.

Not exactly the most beautiful solutions, but they usually work well.

You might be interested in looking at process_includes.py.  It is part
of the generateDS.py package.  It reads and parses an XML Schema
(using lxml, of course) and replaces the include and import
elements in that document with the included document. 
process_includes.py is imported and used by generateDS.py itself,
but you can also run it from the command line.

You can find the latest version of generateDS.py here:

    http://www.rexx.com/~dkuhlman/#generateds-py-generate-python-data-bindings-from-xml-schema

or at the Python project index:

    http://pypi.python.org/pypi

If you try it, let me know if you have questions, suggestions,
etc..

We finally managed to get a build going by forcing an older version of
libxml2 (2.7.3).  Why would the build succeed with 2.7.3 but not with
2.7.7?  This is with the system python (2.5) if it matters.

Did you make sure that you used the same compiler/linker flags in both 
cases? The error above suggests that the compiler was not correctly 
configured, maybe it tried to build for both i386 and ppc (likely because 
CPython was built for both), but only an i386 build of libxml2 was 
available for linking.

and fwiw, I did not succeed in getting lxml built on my Mac,  and as  
with F Wolff, I use the system Python.

I will give 2.7.3 a shot tho.

I used the same command without customising any of the compiler or
linker flags. The same version of lxml (latest, 2.2.6) with the
differing versions of libxml2 produced the different results. In both
cases it was a static build as recommended by the installation
documentation.

I don't have access to the original machine, but just duplicated the
issue with clean lxml from SVN trunk.  The commands were just
python setup.py clean
python setup.py build --static-deps
with no files modified.

Does this help?

The problem appears to be a botched 10.4 SDK.
The library under /Developer/SDKs/MacOSX10.4u.sdk/usr/lib/libz.dylib  
does not have a gzdirect although the header file says otherwise. The  
one in the 10.5 sdk and under /usr/lib
have the function.
As a test you could try moving the dylib from 10.5 to 10.4 and see if  
it works.
I do not know how to fix that in an easy way that does not break  
universal builds though.

Kind regards,
Michael

Answering my own mail. Removing isysroot from the CFLAGS and LDFLAGS  
fixes the problem. I think this also means that the resulting lib most  
likely won't work under 10.4.
I wonder if this is needed though.

Subject: [lxml-dev] Relax NG validation question
Message-ID: <p2v9cee7ab81005040909re92e334cv7f80bbf203a43dee@mail.gmail.com>

I've been using jing to validate documents against a schema written in
the RelaxNG compact syntax. I'd like to use lxml to validate instead
of using jing.

After converting the schema to the XML syntax using trang, I'm loading
the schema like so:

>>> import lxml.etree
>>> doc = lxml.etree.parse("top.rng")
>>> schema = lxml.etree.RelaxNG(doc)
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "relaxng.pxi", line 84, in lxml.etree.RelaxNG.__init__
(src/lxml/lxml.etree.c:114962)
RelaxNGParseError: xmlRelaxNG: include middle.rng has a define
anyElement but not the included grammar, line 9

I suspect something about the include structure of my schema is
causing lxml this heartburn.  I've reproduced this with a cut-down
version of the schema, but I'm using the same include structure as the
original, since I suspect that's essential (and I'd like to retain
that instead of restructuring the actual schema).

My schema is written as three files (attached):

base.rng
    This is really just a very-slightly-modified copy of the Atom schema.
    It defines an "anyElement" pattern.  This can be loaded on it's own.

middle.rng
    This includes and extends base.rng.  It makes no specific mention of
    the "anyElement" pattern.  This can be loaded on it's own.

top.rng
    This is the top-level schema that I actually care about validating; it
    overrides the "anyElement" pattern as part of the include of
    middle.rng.  Building the RelaxNG object from this document causes
    the exception shown above.

Any ideas?  I'm using Python 2.6.5 and lxml 2.2.6, libxml2 2.7.7, and
libxslt 1.1.26.

Subject: [lxml-dev] Newline while outputting a XML file.
Message-ID: <y2vc354da471005041136xc60c278dydf4401090a1ba67@mail.gmail.com>

Hello everyone.

I am developing a Python application that interprets/ writes XML files and I
will be using lxml for this.

However when writing to the XML using lxml, how can I force it to do a
newline on every new tag? What I mean by this is, consider the following
code: http://codepad.org/boEQxxqU

The output of this code is: <html><head><title>Trying</title></head></html>

I want the output to be:

<html>
<head>
<title>Trying</title>
</head>
</html>

Sorry if this question is too noobish, but I am just beginning.

pretty_print=True does it.

etree.tostring(yourtree, pretty_print=True)

Sorry for reopening this thread and not noticing earlier, but etree.tostring
returns a string. I need to output the 'pretty printed' XML to a file and so
I did a <filename>.write(<string>)

I was wondering:

1) Is it acceptable to output a XML file like this, i.e. using a string
instead of the etree.write method?

2) When outputting files, what is preferred: the normal way lxml does it or
pretty printing it?

Yes, why not? Still, I think the straightforward way would be to use the _ElementTree.write() method which also supports the pretty_print keyword.

Depends on your use case. If space is of concern you wouldn't want to pretty-print and add add extra, non-significant whitespace. If whitespace in the document is of significance you wouldn't want to garble it by adding extra whitespace. If (human) readability is your prime concern you probably want to pretty-print.

Subject: [lxml-dev] LD_LIBRARY_PATH issues
Message-ID: <w2vc3b0259b1005050117ufe0051eco9d388b5e7614ea3@mail.gmail.com>

Hi all,

Here is my wierd problem. I am using lxml v 2.2.6 on a custom python (2.6.1)
installation that i did for a project. I use  extensively LD_LIBRARY_PATH
for setting the env variables for libraries to be loaded at runtime.

I am getting this error while running.

ImportError:
/home/tomary/Python/2.6.1_x32/lib/python2.6/site-packages/lxml-2.2.6-py2.6-linux-x86_64.egg/lxml/etree.so:
undefined symbol: xmlSchematronSetValidStructuredErrors

It seems that this error occurs because the wrong version of libxml2 is
getting loaded. Though I have set up the correct version in the right place
at the front of LD_LIBRARY_PATH.

Please help.

Regards,
Yogesh Tomar

When I removed the isysroot, it seemed to pass the problematic part of
the build (although I then hit issues with cython which I guess is
unrelated).

Changing 4->5 in the issysroot parameter didn't seem to work well,
although the error is entirely different (error building memmove.c which
seems to be part of libiconv).

This should not affect cython in any way as far as I see it.

I would leave it as it is, although it won't work on 10.4 anyway given
the fact that libz does not seem to provide the function. Do you need
10.4 support?

I don't need 10.4 support.  In fact, I don't even need universal
binaries (at the moment, at least).

I don't know what would be best to do in lxml trunk for future releases.
Should we maybe special case for OSX < 10.5 and force the use an older
libxml2?

Thanks for your help, Mike.

I would do the same as with iconv, build zlib as well, then we get
around the we have an old lib problem.

Yes, I had this problem back in the day (this was on a Mac OS X platform). If I recall correctly, the problem was compounded by the fact that lxml was reporting that it had loaded the correct libxml2, but was actually not.

I think part of my solution was to make sure that the right libraries were loaded at compile time;  also, check this old thread for more clues:

Hello,

I am trying to use the software "inkscape" with its extension inkscape2tikz
(http://code.google.com/p/inkscape2tikz/)

But I got an error, which needs the lxml-wrapper: 

"The fantastic lxml wrapper for libxml2 is required by inkex.py and 
therefore this extension. Please download and install the latest version from
http://cheeseshop.python.org/pypi/lxml/, 
or install it through your package manager by a command like: sudo apt-get

a) I was guessing, that Python is already installed on OS X?
b) Where can I get this for OS X and how to install it?

I would be very thankful for any advice
sincerely

a) Yes

b) you could follow the convenient instructions just above your questions

I suppose that if you are not versed in the ways of python you might be forced to read the supplementary material at the cheeseshop.

Or, you could search this group (which is, sadly, a chore, unless you know how to use google to do it by specifying "lsml osx site:codespeak.net").  This topic is discussed pretty regularly.

Message-ID: <AANLkTinitOuJ6VsurWMjqchWFz8WIYci9oAjQfMdC_7n@mail.gmail.com>

Hello everyone.

I am new to Python and this is the first time I will be doing proper
development using a library.

I will be using lxml for my project. Since I am new, I obviously don't know
the standard method of doing stuff, so as to say. My project involves a XML
parser in Python.

Can anyone point me to some project that implements XML parsing with lxml /
Python so that I can study the source code just to see how things are done.
A small and compact project would do wonders. I know how to do stuff after
reading the documentation, but if I see some sample code, it would help me
in understanding stuff better. I tried to find some project related to this,
but I was not successful.

Any inputs would be appreciated.

Here's some documentation on using lxml with Python:

     http://www.nmt.edu/tcc/help/pubs/pylxml/

Here is a project I just finished, "docbookindex: ID indexer for
DocBook".  This program reads a DocBook-XML document and generates
an outline-style list of the id attributes of all the sections.

     http://www.nmt.edu/tcc/projects/docbookindex/

This project illustrates a number of useful techniques:

   1.  Parsing a DocBook-XML document with lxml.

   2.  Direct generation of XSL-FO (XSL Formatting Objects)
       from a Python script, for rendering into a PDF file.

   3.  Lightweight literate programming: the DocBook document
       containing the documentation for the project also
       includes the actual source for the program.  This
       inverts the common pydocs/JavaDocs convention that
       embeds documentation within the source.

Here's another application that uses lxml to parse XML.  This is
part of my system for publishing ornithological field records on
the Web.  First, the external specification, which includes a
Relax NG schema for the document, and specifications for the
Python interface:

     http://www.nmt.edu/~shipman/aba/doc/

The actual implementation of the Python interface is another
lightweight literate programming project:

     http://www.nmt.edu/~shipman/aba/doc/pyims/

Yet another literate project: this one processes an XML representation
of a taxonomy of North American Birds.  External specification:

     http://www.nmt.edu/~shipman/xnomo/

Implementation:

     http://www.nmt.edu/~shipman/xnomo/ims2/

I have been working with XML since the mid-1990s, using several different
Python interfaces.  The lxml package has made this kind of work much
easier.

Subject: [lxml-dev] Trying to build lxml for Mac OS X >= 10.4 with zlib and
	iconv
Message-ID: <d4816b05dd71ed7bc6206c7cfd2185d4.squirrel@mail.urheberrecht.org>

Hello,

I am trying to build lxml 2.2.6 for Python on OS X 10.4 and up (for PPC
and i386) using static libs for libiconv and libz. The build seem to go
fine, but I am experiencing import problems.

Here are the steps I am following:

- Downloading and extracting lxml 2.2.6

- Placing zlib-1.2.5, libiconv-1.13.1, libxml2-2.7.7, and libxslt-1.1.26
in the 'libs' sub folder

- Using a modified 'buildlibxml.py' (based on a version originally done by
Stefan) everything seems to compile without errors using:
"python setup.py build \
--static-deps \
--libxml2-version=2.7.7 \
--libxslt-version=1.1.26 \
--libiconv-version=1.13.1 \
--zlib-version=1.2.5"

- Looking into 'build/tmp/libxml2/lib' shows six libraries: libz.a,
libiconv.a, libcharset.a, libxml2.a, libxslt.a, and libexslt.a. lipo says
all are PPC+i386 (two way Universal)

- After doing python setup.py install I can do "import lxml", but "import
lxml.html" fails with:
"ImportError:
dlopen(/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/lxml/etree.so,
2): Symbol not found: _libiconv_close"

I don't know how to proceed from here, especially as during the build of
libxml2 it seems to pick up 'libiconv.a' correctly from:
"libtool: link: gcc -arch ppc -arch i386 -isysroot
/Developer/SDKs/MacOSX10.4u.sdk -O2 -pedantic -W -Wformat -Wunused
-Wimplicit -Wreturn-type -Wswitch -Wcomment -Wtrigraphs -Wformat
-Wchar-subscripts -Wuninitialized -Wparentheses -Wshadow -Wpointer-arith
-Wcast-align -Wwrite-strings -Waggregate-return -Wstrict-prototypes
-Wmissing-prototypes -Wnested-externs -Winline -Wredundant-decls -arch ppc
-arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -o xpath1 xpath1.o 
../../.libs/libxml2.a
-L/Users/admin/Desktop/lxml-2.2.6/build/tmp/libxml2/lib -lpthread -lz
/Users/admin/Desktop/lxml-2.2.6/build/tmp/libxml2/lib/libiconv.a -lm"

The only strange thing I can see is something lwhere it says '-liconv':
"/bin/sh ../libtool --tag=CC   --mode=link gcc  -arch ppc -arch i386
-isysroot /Developer/SDKs/MacOSX10.4u.sdk -O2 -pedantic -W -Wformat

-L/Users/admin/Desktop/lxml-2.2.6/build/tmp/libxml2/lib -liconv -lm  "

But I don't know how to change this.

So now I am a bit lost. Any help would be very much appreciated!

Thanks, Pascal

PS. Let me know if I should post the modified 'buildlibxml.py'.

"apt-get install" is a Debian/Ubuntu/etc. command that won't work on OS-X. 
Here's how to do it:

Using '--without-iconv' for libxml2 in 'buildlibxml.py' I can get it running.

Python 2.5.4 (r254:67917, Dec 23 2008, 14:57:27)
[GCC 4.0.1 (Apple Computer, Inc. build 5363)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from lxml import etree
>>> from lxml import objectify
>>> from lxml import html

I am still unclear about why the build will not take up libiconv.a
correctly. Maybe it is trying /usr/lib/libiconv.la? This was happening the
first time I tried this. Any hints still very welcome, as I would really
like to have the build pick up the latest libiconv.

If I should get this working in the meantime  I'll report back (including
eggs, of course :-).

Best regards,

Pascal

So I'm trying to figure this out as well, running on MacOS 10.5.8 with 
Python 2.4 and trying to install lxml 2.2.6.  I tried forcing libxml2 to 
2.7.3, but I'm still getting the undefined symbols error:

Undefined symbols for architecture i386:

      ___xmlParserInputBufferCreateFilename in libxml2.a(xmlIO.o)

I'm not sure how to remove isysroot from CFLAGS and LDFLAGS 
as was mentioned in another post; I'm trying to use a buildout 
to install currently.

Any suggestions anyone could make would be most appreciated.  
I've been banging my head against this issue for two days straight.

Thanks!

This is getting way too complicated by now. Maybe lxml should just switch 
to requiring buildout for the libraries, instead of trying to build them by 
itself in its setup.py script.

That shouldn't matter.

See buildlibxml.py.

So the above is from a buildout? Which are you using?

Take a look at buildlibxml.py line 282 and 283. Just remove the isysroot
there.

Hope that helps,

Message-ID: <20100518223507.16e909dc@wp01>

Hello,
I use CentOS 5.2 without root access and therefore I installed Python
in my home folder.

Unfortunately, I was not able to get lxml running in the following way:
------
ftp://xmlsoft.org/libxml/

cd ~/temp/libxml2-2.7.7
$ configure --prefix=/home/mit/bin/libxml2
$ make
$ make install

$ cd /home/mit/programs/python/lib/python2.6/site-packages
$ ln -s /home/mit/bin/libxml2/lib/python2.6/site-packages/* .

----------
ftp://xmlsoft.org/libxslt/

$ ./configure --prefix=/home/mit/bin/libxslt
--with-libxml-prefix=/home/mit/bin/libxml2

$ make
$ make install

$ cd /home/mit/programs/python/lib/python2.6/site-packages
$ ln -s /home/mit/bin/libxslt/lib/python2.6/site-packages/* .

---------
$ cd ~/temp/lxml-2.2.6/

$ python setup.py install
--with-xml2-config=/home/mit/bin/libxml2/bin/xml2-config
--with-xslt-config=/home/mit/bin/libxslt/bin/xslt-config
--------

I got errors by testing the lxml in the following:
 
$python

Try passing the --auto-rpath option. Or, even better, use --static-deps=true.

How can I use --static-deps=true. Could give me an example please?

I got a recipe from a site online 
(http://pypi.python.org/pypi/z3c.recipe.staticlxml
) and modified it slightly.  Strangely, just after I posted my
question, I decided to try starting my buildout over in a different
directory as a final attempt and it worked perfectly.  I'm not sure
what the difference was, but it's working fine now.

Thanks for your help!

The "--static-deps" option requires FTP access to the servers that serve 
the libxml2 distribution. Seems like you don't have that.

I gave FTP access now, but the installation failed with a "bad value":

You didn't read the error message. Pass "-fPIC" in your CFLAGS environment 
variable.

Here are two approaches:

>>> from StringIO import StringIO
>>> from lxml import etree
>>> parser = etree.XMLParser(remove_pis=False)
>>> xString = """<?xml version="1.0" encoding="utf-8" ?>
... <?xml-stylesheet href="../xsl/index.xsl" type="text/xsl" ?>
... <root>
... </root>
... """
>>> xTree = etree.parse(StringIO(xString), parser)
# The ElementTree way
>>> xTree.getroot().getprevious()
<?xml-stylesheet href="../xsl/index.xsl" type="text/xsl" ?>
>>>
# The XPath way
>>> xTree.xpath('/processing-instruction()')
[<?xml-stylesheet href="../xsl/index.xsl" type="text/xsl" ?>]
>>> procInstruction = xTree.xpath('/processing-instruction()')[0]
>>> procInstruction.text
'href="../xsl/index.xsl" type="text/xsl" '

XML and related technologies don't define an API for access to the
innards of a PI, so you'll have to use text processing tools to parse
the pseudo attribute/value pairs.

Best wishes,
Chuck

Hi, 

Wednesday 19 May 2010

> Library is perfect , but I have a small problem.
> Can someone give me an advice of how to get  href = ...... - path to xsl
> file from the following xml-file :

Try this one:

------------------
tree = etree.XML("""<?xml version="1.0" encoding="utf-8" ?>
<?xml-stylesheet href="../xsl/index.xsl" type="text/xsl" ?>
<root>
</root>
""")
root = tree.getroottree()
stylesheet = root.xpath("/processing-instruction('xml-stylesheet')")[0]
print stylesheet.text
------------------

Probably there are other methods. :)

Note, a processing instruction just knows a target (here: xml-stylesheet) and 
its content (everything in between "<?xml-stylesheet" and "?>"). A processing 
instruction has no concept of attributes.

As such, you can get only text which you have to parse by yourself. This can 
be done by a regular expression. For example:

------------------
import re
m=re.search('href\s*="([a-zA-Z0-9./\-\\+%]+)"', stylesheet.text)
print m.groups()
('../xsl/index.xsl',)
------------------

Depending on what you expect in the href "pseudo-attribute", you have to 
improve the pattern in the above regular expression.


Hope that helps,
  Tom

I'd swap the variable names here.

getprevious() will do just fine.

lxml.etree special cases the xml-stylesheet PI, though, so you can use 
get() and set() on it, and ask it to parse the stylesheet.

Hey developers :)
we're already excited about using lxml in our project, though can't
quite get it to work.
First of all: We (me and another guy) are both running Ubuntu 10.04
x64 and Python 3.

It began when easy_installing the package:

--

It looks like python (v3?) is complaining about v2 features?


Anyway, importing works (at least, it seems so):

$ python3
>>> from lxml import etree
>>>

However, we can't get our code to work:

--
import socketserver
from lxml import etree
#from xml.etree import ElementTree as etree

import settings

class CloudiaServer(socketserver.ThreadingMixIn, socketserver.TCPServer):
	pass

class RequestHandler(socketserver.StreamRequestHandler):
	def handle(self):
	
		for event, element in etree.iterparse(self.rfile):
			if event != 'end':
				continue
			
			print(element.tag)
			print(str(element.attrib))
			print(element.text)
			
			element.clean()
	
if __name__ == '__main__':
	server = CloudiaServer((settings.host, settings.port), RequestHandler)
	server.serve_forever()
--

As soon as our client connects and sends b'<foo
bar="quux">text</foo>', the server process outputs:

--
Exception happened during processing of request from ('127.0.0.1', 39620)

Does this maybe have something to do with essentially parsing a byte stream?

Excuse me, I forgot to add that replacing lxml with xml.etree, which
can be seen at the beginning of the code, works like a charm. (Of
course, only if you comment out the element.clean() line.)

Hmmm, looks like these two files are not used in the test suite.

Anyway, unless you really want to use them, you'll be fine with all the rest.

That's because you are passing a byte string as path. Might be a bug in 
Py3, don't know. Passing a unicode string instead will help.


> Does this maybe have something to do with essentially parsing a byte stream?

Unless "self.rfile" *is* the byte stream - no. XML is a sequence of bytes 
anyway. In case you mixed up the interface and self.rfile actually contains 
the data instead of a filename, wrap it in a BytesIO instance.

So, are those two files actually part of the test suite or do they
belong to the library and just aren't tested in the test suite for
Python 3? Either way, this is a bug which should be reported, isn't
it?

Path? Filename? Doesn't iterparse expect a file-like object to read()
from? See http://codespeak.net/lxml/tutorial.html#event-driven-parsing.
self.rfile is such a file-like object with read access to the bytes
coming in through the socket (as described here:
http://docs.python.org/release/3.1.1/library/socketserver.html).

Anyway, xml.etree does its thing perfectly here and takes the bytes
stream representing ASCII characters (as of now, will be UTF-8 later
on) without complaining (but we need proper namespace support so it's
not an option). As lxml promises to be 99% compatible to xml.etree,
something must be wrong here.

Should I file a bug report?

Subject: [lxml-dev] Using XMLSchema to validate a document with multiple
	namespace pairs in schemaLocation attribute
Message-ID: <AANLkTikCaNuGUTn4aNxk4ruy3sv3IKdX7Lba9frZhJq9@mail.gmail.com>

We have been trying to use the XMLSchema validation capabilities in
order to validate the result that we get from a WMS server. We are
having problems because the document that we are trying to validate
lists multiple schemas in the schemaLocation attribute. Is there
currently a way to accomplish this with lxml/libxml2? I have attached
an example of what we are attempting.

lxml: 2.2.2
libxml2: 2.7.3

Thank you,
Aron

The latter.

Sure, thanks for doing that.

Both.

Ok, so I misinterpreted the error trace. The respective code in lxml.etree 
needs to be somewhat flexible and ended up a bit too fragile. So, if you 
pass a "non-standard" file-like object, it might end up raising an 
exception like this.

Here's a fix. Take care to use Cython 0.12.1 when you build from patched 
lxml 2.2.x sources.

Subject: [lxml-dev] Building Python2.6 Windows eggs
Message-ID: <AANLkTinwCI8ddzWs3vlRj2jTDootvqpmCwXDOYarly4c@mail.gmail.com>

I've been unable to build lxml under windows using mingw, having
followed the instructions from:

 * http://plone.org/documentation/kb/using-buildout-on-windows
 * http://codespeak.net/lxml/build.html#static-linking-on-windows

The full error message is attached, but this seems to be the same
undefined refernece problems people have run into before (e.g.
http://osdir.com/ml/python.lxml.devel/2007-07/msg00039.html).

Any idea what I'm doing wrong? Or do I need visual studio?

It would be great if someone could build a python 2.6 Windows egg and
upload it to pypi!

Hey Laurence,

there is one in version 2.2.4. I was also searching my ass of and then 
accidentally clicked on version 2.2.4 :-).

http://pypi.python.org/pypi/lxml/2.2.4

Subject: [lxml-dev] Confused as to use a class or a function: Writing XML
	files using lxml and Python
Message-ID: <AANLkTikLAjDnvMZ_hayoW_yOpiR82sXFAaru571-7Fhw@mail.gmail.com>

Hi.

I need to write XML files using lxml and Python.

However, I can't figure out whether to use a class to do this or a function.
The point being, this is the first time I am developing a proper software
and deciding where and why to use a class still seems mysterious.

I will illustrate my point.

For example, consider the following function based code I wrote for adding a
subelement to a etree root.

from lxml import etree
>

> root = etree.Element('document')
>

> def createSubElement(text, tagText = ""):
>
etree.SubElement(root, text)
>
# How do I do this: element.text = tagText
>

> createSubElement('firstChild')
>
createSubElement('SecondChild')
>

As expected, the output of this is:

<document>
>
<firstChild/>
>
<SecondChild/>
>
</document>
>

However as you can notice the comment, I have no idea how to do set the text
variable using this approach.

Is using a class the only way to solve this? And if yes, can you give me
some pointers on how to achieve this?

I'm not sure what you mean by "class or function", but you likely want to 
read the lxml tutorial as well as the ElementTree tutorial. Both are linked 
from the home page.

I've encountered the same problem. As far as I can tell, the problem
lies with the libxml2 version that is used. This bug apparently is
fixed in the libxml2 2.7.7 (from the release notes: "598785 Fix
nanohttp on Windows"), but there are no windows binaries available for
that version yet.
Apparently the bug was introduced in libxml2 2.7.4 (with "59501 avoid
select and use poll for nanohttp"?)

The compiled windows versions of lxml seem to be affected from lxml
2.3 and up. I've tried building later versions of lxml with older
libxml2 (using the instructions from the lxml website), and this seems
to work. So I'm pretty confident that I'm right about the cause of the
problem. I wouldn't know how to compile libxml2 itself though.

Hope this helps, or at least clarifies the issue.

greetings,

Steven

Thanks Steven. Which compiler do you use for building lxml on Windows?
(I didn't have any luck with MinGW.)

Subject: [lxml-dev] Accessing text of an element when using itemparse
Message-ID: <20100525164615.GA3900@Pinson>

Hello,

When using itemparse, during 'start' event, is the text of an element accessible ? Or text can only be accessed during 'end' event ?



from sys import stdout
from lxml.etree import iterparse

if  __name__ == '__main__':
  context = iterparse("in.xml",events=('start','end'))
  for event, element in context:
    if event=='start' and (type(element.text) is unicode or type(element.text) is str):
      stdout.write(element.text.encode('utf-8'))



I get different results with this code and the same one replacing "if event=='start'" by "if event=='end'" : is it normal ?

Best regards,

Alex Bernier

No. Any content may or may not be available at this point, there is no

Yes.

Thanks for the fix! I'm apparently too dumb to apply the .diff using
patch (there was always some strange error occuring), so I patched
apihelpers.pxi manually. :D
When building the patched 2.2.6 sources, which I downloaded from
http://pypi.python.org/packages/source/l/lxml/lxml-2.2.6.tar.gz),
using Cython 0.12.1 I receive the following error:

I tried the same with the newest SVN sources (lxml 2.3 r74722) and it
worked (both, building and the bugfix). For anyone who cares I
uploaded the egg: It's available on
http://codethief.eu/kram/_/lxml-2.3dev-py3.1-linux-x86_64.egg

P.S. Any plans to migrate to a distributed revision control system
like Git or preferably (in my opinion) Mercurial? That'd make many
things a lot easier. Just take github.com and bitbucket.org which
expose a much nicer user interface than SVN does. :)

This is only peripherally related, but XInclude hasn't worked for me (as
in dumps core) with lxml since upgrading to libxml2 2.7.4. If the
windows binaries get rebuilt, might be two good reasons to link against
2.7.3.

Haven't filed a bug report yet, as it's not a critical part of my system
so I haven't yet been able to free up time to come up with a good test
case.

The next binaries will hopefully use libxml2 2.7.7. No idea if this is 
fixed there, though.

No such planning, no. I actually got used to using svk for lxml. Works ok 
in most cases, lacks a bit of ease compared to Mercurial, but keeps the 
current repo as is.

I've been able to test against 2.7.4, 2.7.6 and 2.7.7, and XInclude is
broken on all of them for me. Same code worked on 2.7.3 (and same
version of lxml across 2.7.3 to 2.7.4 upgrade), so I'm pretty sure
that's the magic version.

I suspect the changes made for this bug fix, since it's effecting the
right part of the code, and the timing is right:
https://bugzilla.gnome.org/show_bug.cgi?id=584220

But like I said, mostly I need to come up with a simple test case so I
can report it to the libxml2 folks.

Subject: [lxml-dev] Force element content to be string
Message-ID: <20100531145102.51434veknbsgx3n4@webmail.ssl-gateway.de>

Hi all!

I have a bit of XML which I want to parse via lxml.objectify.

from lxml import objectify
node = objectify.fromstring('''
<Item>
   <ASIN>0747532745</ASIN>
   <ItemAttributes>
     <Author>Joanne K. Rowling</Author>
     <Manufacturer>Bloomsbury Publishing</Manufacturer>
     <ProductGroup>Book</ProductGroup>
     <Title>Harry Potter and the Philosopher's Stone</Title>
   </ItemAttributes>
</Item>
''')

I have the following problem: node.ASIN is evaluated to integer value  
747532745 but should be a string ('0747532745').

There is no way for me to influence the incoming XML, so any py:pytype  
magic or adding a schema is out of the question. Is there a way to  
ensure that ASIN elements are always evaluated to a string?

Cheers,
Seb.

Just add the type attribute after parsing and remove it before serialisation.

Alternatively, you can register your own Element type for the ASIN tag. 
There should be something about that in the objectify docs.

Thanks for the tip. I wrote my own class lookup

from lxml import etree
class MyLookup(etree.CustomElementClassLookup):
     def lookup(self, node_type, document, namespace, name):
         if name == 'ASIN':
             return objectify.StringElement

lookup = MyLookup()
parser = etree.XMLParser()
parser.set_element_class_lookup(lookup)
node = objectify.fromstring(xml, parser)

which now returns the right element type.

node = objectify.fromstring(xml, parser)
objectify.annotate(node)
print objectify.dump(node)

Item = None [_Element]
   * py:pytype = 'str'
     ASIN = '0747532745' [StringElement]
       * py:pytype = 'int'
     DetailPageURL = 'http://www.amazon.de/Harry-...' [_Element]
       * py:pytype = 'str'
     ItemAttributes = None [_Element]
       * py:pytype = 'str'
         Author = 'Joanne K. Rowling' [_Element]
           * py:pytype = 'str'
         Manufacturer = 'Bloomsbury Publishing' [_Element]
           * py:pytype = 'str'
         ProductGroup = 'Book' [_Element]
           * py:pytype = 'str'
         Title = "Harry Potter and the Philosopher's Stone" [_Element]
           * py:pytype = 'str'

How do I make it fall back to objectify.ObjectifyElementClassLookup?

Seb.
