[lxml-dev] Reparenting a node
by Lawrence Oluyede 30 Jan '23

30 Jan '23

I have a doc A and a doc B, I'd like to put a node extracted from A in the document B but I always get a ValueError: ValueError: Element is not a child of this node. I didn't find any "setparent" in the API. How can I do this? -- Lawrence, oluyede.org - neropercaso.it "It is difficult to get a man to understand something when his salary depends on not understanding it" - Upton Sinclair

[lxml-dev] Checking whether a node is a comment/element
by Geoffrey Sneddon 11 Jan '23

11 Jan '23

Hi, What's the best way to check whether a given node is a comment or an element? For the former, I'm currently using isinstance(node, etree._Comment), which is rather obviously sub-optimal. -- Geoffrey Sneddon <http://gsnedders.com/>

[lxml-dev] lxml 2.0.5 released
by Stefan Behnel 11 Jan '23

11 Jan '23

Hi all, lxml 2.0.5 is on PyPI. This is a bug-fix-only release of the stable 2.0 series. Have fun, Stefan 2.0.5 (2008-05-01) Bugs fixed * Resolving to a filename in custom resolvers didn't work. * lxml did not honour libxslt's second error state "STOPPED", which let some XSLT errors pass silently. * Memory leak in Schematron with libxml2 >= 2.6.31.

Hi all, I added the lxml project to launchpad, the Ubuntu Bug-Tracker. It also has a FAQ engine and a couple of other goodies. https://launchpad.net/lxml It's easy to sign up for launchpad, BTW, no 90%-footnotes-contract. Have fun, Stefan

[lxml-dev] Building LXML Trunk
by Sidnei da Silva 31 Aug '22

31 Aug '22

Hi, I've tried to build lxml from trunk today, on Win32. Got the following error: src\lxml\etree.c(880) : error C2059: syntax error : ')' src\lxml\etree.c(881) : error C2059: syntax error : ')' src\lxml\etree.c(882) : error C2059: syntax error : ')' src\lxml\etree.c(883) : error C2059: syntax error : ')' Any clue? Smells like a Pyrex issue? -- Sidnei da Silva Enfold Systems http://enfoldsystems.com Fax +1 832 201 8856 Office +1 713 942 2377 Ext 214

[lxml-dev] setuptools issues with python2.6 maint
by Michael Bayer 04 Oct '09

04 Oct '09

My apologies for dumping a bad build on the list here, but googling returned absolutely nothing for this one. I haven't had this issue before so it may be related to my usage of the latest python 2.6 mainentance branch which I got from http://svn.python.org/projects/python/branches/release26-maint . It builds fine if I run a straight distutils build without setuptools being installed. Otherwise I get the below - tested against 2.1.5, 2.2, and 2.2.2, any ideas are appreciated. root@stageassets lxml-2.2.2]# /usr/local/bin/python setup.py install Building lxml version 2.2.2.

[lxml-dev] current trunk includes static build for libiconv
by Stefan Behnel 03 Sep '09

03 Sep '09

Hi, since there were problems also with libiconv on MacOS recently, I added libiconv to the list of libraries that "--static-deps" builds. I'd be happy to get some feedback on this to see if it actually works for those who reported problems. http://codespeak.net/lxml/build.html#subversion http://codespeak.net/lxml/build.html#building-lxml-on-macos-x Note that the trunk builds as lxml version "2.3dev" now. Copying over the buildlibxml.py script to another lxml version should also work. http://codespeak.net/svn/lxml/trunk/buildlibxml.py Stefan

I heard libxml2/lxml is a PITA to build on windows so being inexperienced I'll not bother attempting it before ruling out alternatives. Is there a build bot with dist zips of the latest revisions available anywhere for windows ?
