[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?

Memory leak when parsing XML files in sequence?
by Maarten van Gompel (proycon) May 3, 2013

May 3, 2013

Hi, I stumbled across what I think it a memory leak within the lxml module. I am parsing literally millions of mostly small XML files, in sequence. In the following, simplified, fashion: index = glob.glob('/path/to/dir/with/huge/number/of/xml/files/*xml') for f in index: d = lxml.etree.parse(f) The problem is that (almost) every iteration, memory usage is increased. But note that d gets overwritten everytime and the reference to the previous document should be lost (I don't … [View More]

[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]

Attribute encoding.
by Evgeny Turnaev Dec. 3, 2011

Dec. 3, 2011

Hello. Is there any reason why attributes of Element returned as bytestring if only contains ascii? In my application i need it to be unicode always. Is there a way to force lxml return element attribute as unicode? What is the preferred way of getting attributes as unicode? 1. value = elem.attrib['foo'] if isinstance(value, str): encoding = elem.getroottree().docinfo.encoding value = value.decode(encoding) 2. value = elem.attrib['foo'] if isinstance(value, str): value = value.… [View More]

License for lxml.cssselect
by Laurence Rowe Nov. 23, 2011

Nov. 23, 2011

I just wanted to confirm that lxml.cssselect was under the BSD license. Reading https://github.com/lxml/lxml/blob/master/LICENSES.txt and https://github.com/lxml/lxml/blob/master/doc/licenses/BSD.txt implies that it is BSD licensed and copyright by Infrae, though it was originally contributed by Ian Bicking according to the changelog (https://github.com/lxml/lxml/blob/master/CHANGES.txt#L1429). The reason I'm asking is that for Diazo I need the location path compatibility that discontinued in … [View More]
