** XML and HTML parsing
*** If Emacs is compiled with libxml2 support (which is the default),
two new Emacs Lisp-level functions are defined: `html-parse-string'
(which will parse "real world" HTML) and `xml-parse-string' (which
parses XML). Both return an Emacs Lisp parse tree. See the Emacs
Lisp Reference Manual for details.
two new Emacs Lisp-level functions are defined:
`xml-parse-html-string-internal' (which will parse "real world" HTML)
and `xml-parse-string-internal' (which parses XML). Both return an
Emacs Lisp parse tree.
FIXME: These should be front-ended by xml.el.
