• gh-54873: Backported namespaces prefixes support for xml.sax.expatreader from PyXml (0.8.4) #118317

[freddrake]

The xml.sax.expatreader module pre-dates prefix reporting from Expat, and should be modified to support the feature_namespace_prefixes feature instead of complaining that Expat doesn't support prefixes.

[NicolasDelaby]

the PyXML sax parser support this feature.
May be it can be backported into stdlib ?
