[lxml-dev] lxml has its page on launchpad
by Stefan Behnel 10 Apr '23

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] Checking whether a node is a comment/element
by Geoffrey Sneddon 09 Apr '23

09 Apr '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] 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] 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.

[lxml-dev] Building LXML Trunk

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

thread-specific data for xslt callbacks
by Bob Kline 13 Oct '17

13 Oct '17

I need to make some thread-specific data available to my xslt function callbacks. I think I've sort of reverse-engineered a way to do it, by creating my own parser class, stuffing the data I need into an instance of that class, using the parser instance to parse the XSL/T filter, and then in the extension function following the context argument's context_node to its root tree, which in turn gets me back to my own parser object (and my thread-specific data). Is there a more elegant way to do it that I just haven't yet stumbled across in reading through the API docs? Thanks! -- Bob Kline http://www.rksystems.com mailto:bkline@rksystems.com

Re: [lxml] Fwd: Reg Libxml2 upgrade

Hi Swarnalatha, the previous releases were build with 2.9.3, due to 2.9.4 having a bug regarding schema validation. Unfortunately, 2.9.3 has it's own bugs, too. You can see some previous discussion here: https://bugs.launchpad.net/lxml/+bug/1706375 That discussion was then moved to this mailing list – unfortunately all of its web-accessible archives seem to be broken :(. If you have a newsreader, you can have a look at nntp://news.gmane.org/gmane.comp.python.lxml.devel. The thread title is "Should (Linux) binary wheels include libxml2/libxslt". If you need a quick fix, you can just compile lxml yourself with your own version of libxml2 – that's what we ended up doing.

Please give them a try to see if they work for you. I'm planning to use them in the next binary releases. ftp://xmlsoft.org/libxml2/ On most non-Windows systems, you can build lxml statically with these versions by setting these environment variables: LIBXML2_VERSION=2.9.5-rc2 LIBXSLT_VERSION=1.1.30-rc2 STATIC_DEPS=true (Note that the build will not automatically pick up pre-release versions, unless you explcitly specify the versions above.) If the build fails with a missing "lzma_*" symbol, you can either uninstall the lzma-dev headers, or try the latest lxml master (and pip-install Cython). Stefan

Fwd: Reg Libxml2 upgrade
by Swarnalatha Kannan 28 Aug '17

28 Aug '17

Team, We are using lxml (lxml-3.3.4.win-amd64-py2.7) in my project which gets shipped with libxml2 2.9.0. We would like to upgrade libxml2 to 2.9.4 to mitigate security vulnerabilities (*CVE-2016-4448* ). For this upgrade we have to update lxml which has 2.9.4 libxml2. But latest lxml for 2.7 python 64 bit windows is having 2.9.3. Let me know how to solve the issue? Thanks. Python version used: python-2.7.12.amd64.msi
