[lxml-dev] Help with an error message

[Konstantin Ryabitsev]

Hi, everyone:

I'm having trouble with the following case. One of my automatic import
scripts takes data from one source and submits it to another as an XML
feed. Recently, it started failing because one of the entries contains
a null. The testcase is such:

from lxml.etree import Element
sourcestr = 'Contains a null: \x00'
unistr = unicode(sourcestr, 'utf-8')
elt = Element('foo').text = unistr

Running it will cause the following error:

Traceback (most recent call last):
  File "foo.py", line 6, in <module>
    elt = Element('foo').text = unistr
  File "etree.pyx", line 741, in etree._Element.text.__set__
  File "apihelpers.pxi", line 344, in etree._setNodeText
  File "apihelpers.pxi", line 648, in etree._utf8
AssertionError: All strings must be XML compatible, either Unicode or ASCII

Can someone suggest the best way to deal with this?

Kind regards,
