The C program assumes that the "interesting" elements are one level below the document root. Therefore, the additional level introduced by <statuses> inhibits the program from reaching the correct elements.
Notice that xmlNodePtr provides access to other xmlNode fields so that you can check the tag name and decide whether to go down another level. -W -----Original Message----- From: Gabriel Duarte <[email protected]> Hello! I'm new to libxml, following the instructions and reading examples I could parse a XML file perfectly, but now I got a problem I can't solve by my self. I got this following XML file: <?xml version="1.0" encoding="UTF-8"?> <status> <created_at>Sat Jan 02 20:44:54 +0000 2010</created_at> <id>7309338854</id> <text>TESTE_AGAIN</text> <source><a href="http://apiwiki.twitter.com/" rel="nofollow">API</a></source> <truncated>false</truncated> <in_reply_to_status_id></in_reply_to_status_id> <in_reply_to_user_id></in_reply_to_user_id> <favorited>false</favorited> <in_reply_to_screen_name></in_reply_to_screen_name> <user> <id>13672792</id> <name>Gabriel Duarte</name> <screen_name>biiielduarte</screen_name> <location>Rio de Janeiro</location> <description>Just me!

A possible way to do that would be to make a DTD with some FIXED attribute values declared, to add the "xmlns:scenario=..." and so forth. Another might be to use entities in a wrapper, <!DOCTYPE wrapper [ <!ENTITY include SYSTEM "myfile.xml"> ]> <wrapper>&example;</wrapper> With libxml, you may also be able to do this with xinclude.
