i dont think we ever came to a consensus on xml parsing in ffmpeg.

some ideas:
1. dependency on xml lib like libexpat
2. rewrite small xml parser for libavutil
3. parse xml as text with a bunch of hacks like mplayer does.
4. include regex in ffmpeg

so yes , please submit a patch with libexpat support.
we'll go from there.
