That character is not allowed, so your file is not a well-formed XML document (i.e. it's not XML). http://www.w3.org/TR/REC-xml/#charsets Stefan

Compilation/Installation problems with Mac 10.6 and 10.7
by Jake Lyles 16 Mar '12

Hi all, My latest attempt at installing lxml on Mac is on Mac OSX Lion 10.7.3 I installed with `pip install lxml`. When I open up a python prompt and run: `from lxml import etree` I get the _htmlParseChunk error message: "ImportError: dlopen(/Users/jacob/code/gc/crawler/env/lib/python2.7/site-packages/lxml/etree.so, 2): Symbol not found: _htmlParseChunk Referenced from: /Users/jacob/code/gc/crawler/env/lib/python2.7/site-packages/lxml/etree.so Expected in: flat namespace in /Users/jacob/code/gc/crawler/env/lib/python2.7/site-packages/lxml/etree.so" Any pointers would be welcome. Thanks! -Jake

XSLT - xsltMaxDepth setting
by Fran Boon 09 Mar '12

09 Mar '12

I have an issue with a stylesheet which uses a lot of recursion (converting complex polygons from WKT to GeoJSON) which goes over the 3000 default limit. I can get Xalan to work simply by increasing the stack size but don't know how to get it to work in lxml (which is where I really need it working as my application, Sahana, is a Python one). I read this thread with interest but didn't see where it had got to: http://comments.gmane.org/gmane.comp.python.lxml.devel/5727 Is there any way that I can increase this size from a Python call to lxml? (I did look through the source code, but couldn't see anything) Many thanks, Fran.

Cythoning lxml fails on master
by Simon Sapin 08 Mar '12

Hi, I just tried installing lxml from git master, but Cython fails with hundreds of errors like these: src/lxml/iterparse.pxi:123:33: 'xmlDoc' is not a type identifier src/lxml/schematron.pxi:166:53: Constructing Python tuple not allowed without gil I’m running Cython 0.15.1 and CPython 2.7.2 and 3.2.2 (same result with both.), and installing (while in the git checkout directory) with pip install -e . I could kind of make it work by taking the *.c and *.h files from the latest release. This is good enough for me to work on cssselect, but running the whole test suite segfaults at test_html_prefix_nsmap (lxml.tests.test_etree.ETreeOnlyTestCase) (I’m not surprised by this segfault. The real problem is Cython errors above.) Regards, -- Simon Sapin
