   ^~~~~~~~~~~~~~~~~~~

It’s deprecated because:

• It uses global parser state (not thread-safe).
• It’s less flexible than the newer xmlReader and xmlParserCtxt APIs.
• It doesn’t handle modern XML features (entities, encodings) as cleanly.

Patch reference attached.

imm: old Simple API for XML interface is deprecated [#3387]

xmlSAXUserParseFile() is deprecated. Replace it with a wrapper based on
xmlCreateIOParserCtxt() to ensure safer and more controlled parsing.
