XML parsing advice

XML parsing advice

[Eric Abrahamsen]

I've been asking around on #emacs about this but thought I'd try here as
well: I've recently wanted to parse and edit XML files (both for EPUBs
and the TMX translation memory format). The wiki[1] seems to indicate
that things are largely broken: xpath.el and xpath-parser.el rely on
very out of date libraries. Dom.el works, but apparently can't put its
dom document back into XML.

I need to go the whole round trip: parsing a file, editing nodes and
attributes, and then saving the tree back to an XML file. I can start
doing this myself, but wanted to check if anyone had any better interim
solutions.

Thanks!
Eric

Recent Emacsen can be compiled with libxml2.  Currently this only
provides access to the parser (see libxml-parse-xml-region and
libxml-parse-html-region), but we could extend it to provide access to
other parts of the libxml2 API.

Sounds good to me! Seems like it would make more sense to use the C
libraries than re-implement xpath in elisp...

Should I open a "bug report" and make a feature request?
