[lxml-dev] lxml \ libxslt \ libxml2 leads to apache 2 crash on freebsd/amd64

[Dmitri Fedoruk]

Hello once again,

I've upgdaded my code to be lxml2.0-compatible.

> Entity 'hellip' not defined
Parsing of the incoming data fails when I have html entities in it.

Literally I have this code:

xmlParser = etree.XMLParser( no_network = False, resolve_entities = False )
storedDoc = etree.parse( StringIO.StringIO(reply['data']), xmlParser )

I tried to turn  resolve_entities = True, did not help either. The
point is that all entities are defined in the files included in the
DTD file, and I do not want to validate the data in the runtime - I
have strict time limitations. It worked fine win 1.3.x without special
parser, just with
storedDoc = etree.parse( StringIO.StringIO(reply['data']) )

So, is there any chance to deal with entities in my incoming data
without validating?

> function takes at most 1 positional arguments (2 given)
That was the very string that leads to problems, I had to add the
'encoding' keyword.
return etree.tostring(result_tree, encoding = 'utf-8')

Nevertheless the upgrade did not help.

As I have already said, this happens with only several given
stylesheets. May this be the data\stylesheet problem?

Cheers,
