Oops, this is a problem. Parsing XML would require regex or an XML parsing 
library. Actually, I first wrote this patch using libexpat, but I thought it 
was not worth adding a dependency when I could just use regex.

Now, I think it could be useful: I have a colleague working on adding Smooth 
Streaming playback support to FFmpeg, and for now he uses libexpat to parse 
the manifest. Other adaptive streaming formats such as DASH and HDS have XML 
manifests too, so it could definitively be of use.

What do you think about this? Should I send a patch adding libexpat to FFmpeg 
and the libexpat version of my patch?
