[lxml-dev] etree.cleanup_namespaces() removes namespaces that are used in ns-prefixed attribute values
Hi, would that be a bug or is it just not supported/sanely supportable?
root = etree.fromstring('<root xmlns:xsd=" http://www.w3.org/2001/XMLSchema" xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"><x xsi:type="xsd:integer">42</x></root>') print etree.tostring(root, pretty_print=True) <root xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"> <x xsi:type="xsd:integer">42</x> </root>
etree.cleanup_namespaces(root) print etree.tostring(root, pretty_print=True) <root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <x xsi:type="xsd:integer">42</x> </root>
Note how the XML Schema namespace as used in xsd:integer has been removed.
print etree.__version__ # oldschool ;-) 3.7.2

Hi Holger, since the xsd: prefix is only part of a value (instead of a name), I think this is expected. --dirk Am 02.05.2019, 17:02 Uhr, schrieb Holger Joukl <Holger.Joukl@lbbw.de>:

A missing feature, I'd say. C14N (2.0, will be in lxml 4.4) allows defining a set of elements and attributes where qualified tag names should be detected (and adapted) in their text. That might be a good approach here, too. https://github.com/lxml/lxml/blob/3f0db5d57940eebd418fe86bcbdad39ffe23211d/s...
