Parsing DIDL-Lite xml strings

[lohr free fr]

Hello,
  I have strings with DIDL-Lite xml. I need to parse them (validate, get some elements (title, duration, 
uri)).

If I understand well, gupnp_didl_lite_parser_parse_didl() does two tasks:
1) parse the xml string
2) query the media server about availability of the described media

I only need the first half of the job. Is there a way for that?
(I know that the media servers won't reply to me at the time I process the strings).
What is the easiest way to get elements within a DIDL-Lite xml string?

Best regards
Christophe
