[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?

Tested value modified in validation error message
by Bob Kline July 15, 2022

July 15, 2022

Before I file a ticket, I wanted to check here to find out if this is a known problem (I searched the bug tracker, but didn't see any matches). Our customer is using a commercial XML editor and the editor's implementation of the DOM API sometimes garbles whitespace inside text nodes when serializing XML documents for the document's xml property. This causes schema validation errors when we send that serialization off to be validated against the document type's schema using lxml. The problem we have run into with lxml is that the message property of the error object which comes back in the schema object's error_log has altered the value being validated. So, for example, if the text content of an element in the serialized DOM is "Processing\ncomplete" and the value it was supposed to match in the enumerated valid values is "Processing complete" then the message attribute for the corresponding object in the error_log has Element 'ProcessingStatusValue': [facet 'enumeration'] The value 'Processing complete' is not an element of the set {'Ready for English peer review', 'Ready for English scientific review', 'Ready for English OCCM review', 'Ready for Spanish peer review', 'Ready for Spanish OCCM review', 'Ready for publishing', 'Ready for translation', 'Processing complete'}. In effect saying "the value 'Processing complete' does not match the value 'Processing complete'." Took a very long time for us to figure out that the error message was wrong, and that it should have said ... The value 'Processing\ncomplete' is not an element of the set .... -- Bob Kline https://www.rksystems.com mailto:bkline@rksystems.com

Does findall() return elements in document order?
by Eero Holmström Nov. 5, 2021

Nov. 5, 2021

Hello, I have a simple question: Does the findall() method of lxml return elements in document order? So far, I find empirically that it does, and I have not seen an exception to this rule. But the documentation does not mention anything about the ordering of the elements being returned. Does the implementation still guarantee, that elements are returned in document order? Thanks for your help, Eero

Wheels for Python 3.10 on Windows and macOS
by safihre＠sabnzbd.org Nov. 5, 2021

Nov. 5, 2021

Could you provide binary wheels for Windows and macOS for Python 3.10 through PyPi? All our CI is failing (Windows) or taking ages (macOS) because it has to compile lxml from source. Thank you!
