[lxml-dev] Checking whether a node is a comment/element
by Geoffrey Sneddon 10 Apr '23

10 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

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.

Question about inheritance in cssselect.py
by Dani Litovsky Alcala 23 Dec '22

23 Dec '22

lxml v.4.9 cssselect.py:CSSSelector.__init__ calls on `etree.XPath.__init__(self, path, namespaces=namespaces)` to initialize the parent class. Is there a reason why `super()` or even `super(CSSSelector, self)__init__...` is not used? I bring this up as if I attempt to monkey patch (private project) `etree.XPath.__init__` the current code causes an error ``` TypeError: super(type, obj): obj must be an instance or subtype of type ``` while replacing it with the suggested use of `super()` fixes my error.

can I tell lxml to ignore xmlids?
by Martin Mueller 31 Oct '22

31 Oct '22

Duplicate xmlids have way of creeping into my 60,000 documents. The ids keep the document from parsing, which is helpful in drawing attention to errors, but it makes it harder to correct the errors. I work with documents in the TEI namespace, and I have a very kludgy workaround: I comment out the reference to the schema and change ‘xml:id ‘ to ‘xmlom’. Then I can loop through the document and fix errors with a script. There must be a more elegant way to do this. Is there away of telling lxml: “never mind the duplicate IDs. Just carry on”. Then I can toggle between a script that cares or doesn’t care about duplicate IDS.

Turn three-line block into single?
by Gilles 31 Oct '22

31 Oct '22

Hello, Before I resort to a regex, I figured I should ask here. To find and remove possible duplicates, I need to turn each block into a single line: FROM <wpt lat="46.98520" lon="6.8831"> <name>blah</name> </wpt> TO <wpt lat="46.98520" lon="6.8831"><name>blah</name></wpt> Do you know of a way to do this in lxml? Thank you.
