[lxml-dev] Checking whether a node is a comment/element
by Geoffrey Sneddon April 10, 2023

April 10, 2023

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 Jan. 30, 2023

Jan. 30, 2023

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 Jan. 11, 2023

Jan. 11, 2023

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.

[lxml-dev] confusing xpath performance characteristics
by jholg＠gmx.de Aug. 24, 2012

Aug. 24, 2012

Hi, I ran into some performance characteristics of lxml/libxml2 xpath that I find rather confusing: I try to find the @type attribute of a certain element in an XML Schema (which contains lots of complexType definitions with lots of elements in them; unfortunately I can't post the schema): >>> timeit.Timer(stmt="""xpath(schema)""", setup="""from lxml import etree, objectify; schema=etree.parse('NDM.xsd').getroot(); xpath = etree.XPath('//xs:element[@name="equity"]/@type', namespaces=… [View More]

[lxml-dev] Evaluate XSLT directives inside custom XSLT extension elements
by Marat Dakota Jan. 25, 2010

Jan. 25, 2010

Hi, I have a problem I couldn't find the way to solve. Sadly if it's not possible. That's the code from XSLT extensions tutorial: <xsl:template match="*"> <my:python-extension> <some-content /> </my:python-extension> </xsl:template> Everything's working cool, but I need a bit more: <xsl:template match="*"> <my:python-extension> <something><xsl:attribute name="test"><xsl:value-of select="111" /></xsl:… [View More]

[lxml-dev] Instructions to build on Windows 64-bit?
by Sridhar Ratnakumar Jan. 12, 2010

Jan. 12, 2010

I noticed that the lxml PyPI page provides 64-bit Windows installers [http://pypi.python.org/pypi/lxml/2.2.4 ; lxml-*amd64.exe]. I assume they are statically linked with the libxml/xslt libraries. In the interest of providing 64-bit binaries in PyPM [pypm.activestate.com], may I know how these binaries are built? I tried buildlibxml.py which fails at several steps; and the compiled libraries provided at ftp.zlatkovic.com are 32-bit only. -srid

[lxml-dev] Looking for performance tips for soupparser
by Yannick Gingras Jan. 10, 2010

Jan. 10, 2010

Hi, first of all, I have to say that I really like soupparser. Thanks a lot for it. I use it a lot data mining on a somewhat large document collection that I often revisit to try new ideas. Soupparser is fast but I put a lot of strain on it so I was looking for ways to speed things up. My first idea was to use beaker to cache the root Element object of every document to disk. Unfortunately, Element instances are not pickleable so I have to look for something else. Would any of you … [View More]

[lxml-dev] Is there a 'Generic' XML-to-Relational Database Program?
by Dattatreya Mellacheruvu Dec. 31, 2009

Dec. 31, 2009

Hi All, 1. Is there a python (UTILITY) program that converts 'any' XML to Relational Database program (which uses, say, lxml)? So, the utility program should not only parse the xml, but also understand the most general 'hierarchical' structure of the elements, create tables (say in sqlite) accordingly and insert the data. I have seen many relational DB to xml programs, but I haven't come across one that does the opposite. 2. Is there a UTILITY (program) whtat diplays the most general … [View More]
