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

by Stefan Behnel 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, 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

Q: lxml Windows wheels
by Heiko Nardmann 14 Apr '16

14 Apr '16

I have some trouble using the offered Windows wheels; the following is what I get from pip: Could not find a version that satisfies the requirement lxml (from versions: ) So I had a look at the WHEEL file inside the ZIP lxml-3.6.0-cp32-none-win32.whl to see which requirements are stated inside. Is it okay that 'Tag' is set to 'cp27-none-linux_x86_64' inside that file? Might this be the reason why no version can be found? Maybe someone can enlighten me with respect to wheels? I have to admit that I'm completely new to wheels and quite new to Python packaging but I wouldn't expect metadata with "Linux" inside a Windows wheel? Thx in advance! Kind regards, Heiko Nardmann

cannot load Schematron stylesheet: "<string>:0:0:ERROR:XSLT:ERR_OK: unknown error"
by Rainer Hoerbe 08 Apr '16

08 Apr '16

I am able to reproduce an erroneous behavior with python 2.7 and 3.4l + xml 3.6.0. Processing is correct when using xsltproc directly: import lxml.etree as ET sf = 'rules/schtron/rule04E.xsl' xslt = ET.fromstring(open(sf).read()) transform = ET.XSLT(xslt) # at this point transform.error_log.lasterror contains "<string>:0:0:ERROR:XSLT:ERR_OK: unknown error" The stylesheet is: https://github.com/rhoerbe/saml_schematron/blob/master/rules/schtron/rule04… and has been generated from this schematron: https://github.com/rhoerbe/saml_schematron/blob/master/rules/schtron/rule04… The code works with other (simple?) stylesheets. Are there any restrictions in lxml that prevent the processing of ISO-schematron stylesheets? Or is this a bug that should be filed? Regards, Rainer

soupparser
by Никола Димитров 05 Apr '16

Hello everyone ! Currently working on a project involving scraping and parsing Intranet resources. 'Till now I have used BeautifulSoup, but decided to shave every ms possible thus the switch to lxml. Still, handling most of the encoding issues will be a pain, so naturally I wanted to benefit from bs4's encoding capabilities. Now to do so I have to: >>> from lxml.html.souppareser import fromstring But I am presented with an ImportError; the module BeautifulSoup is not found Of course that super easy to fix, but my question is: Am I missing something ? What's the bigger picture here, so to say or is it just a bug ? On my Window$ computer at the office the module is named bs4, same for the Linux and BSD computers at home. Obviously, I am using BeautifulSoup4 (4.4.1 to be exact). Thank you ! Nikola
