[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

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?

Schema validation fails after replace() call?
by Jens Tröger June 11, 2016

June 11, 2016

Hello, I'm not quite sure if I'm asking a question, or sharing an observation. Is it possible that an lxml.etree instance validates before a replace() call, but not after? The error messages I get from the lxml validation are almost 200 of the same: <string>:440:0:ERROR:SCHEMASV:SCHEMAV_CVC_IDC: Element 'deviation': No match found for key-sequence ['WtC2eoepX'] of keyref 'deviationstyle-refer'. Looking at the actual XML I can positively confirm that the IDs and IDREFs exist and are valid, before and after the replace() call. The new subtree is equivalent to the old one, but there are elements in the whole tree that refer to elements in the replaced subtree. I suspect that this causes the problem. Interestingly: - xmllint validates the new tree when written to a file, and - if I serialize the entire tree (including the new replaced subtree) and parse it back, it validates. This is intended behavior, an odd side effect, or a bug? Thanks! Jens -- Jens Tröger http://savage.light-speed.de/

Unable to find element with xpath
by Stein Rune Risa May 7, 2016

May 7, 2016

I have an XML document that looks like this: https://drive.google.com/file/d/0B4basSIXW5iGNUVfb01ZQkJQUzQ/view?usp=shari… I've previously used lxml for parsing html documents and would like to use it for XML documents as well. I am interested in finding all the "Lap" elements in the XML file and have written some simple python code: sourcefile = f1=open('NAME_AND_PATH_OF_XML', 'r') sourceXML = sourcefile.read() root = etree.fromstring(sourceXML) laps = root.xpath('//Lap') print len(laps) For some reason it cannot find "Lap" in the XML. The XML seems to be valid when I open it with a browser. Any suggestions? Best regards Ziggy999

Question regarding splitting documents
by Pedro Andres Aranda Gutierrez May 5, 2016

May 5, 2016

Hi folks, I'm attaching a small sample program. My intent is to split the HTML snippet into smaller html documents using the <h4> tags as the splitting points. Any clues? Thanks, /PA -- Fragen sind nicht da um beantwortet zu werden, Fragen sind da um gestellet zu werden Gerog Kreisler
