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"?>

ÂÂ<created_at>Sat Jan 02 20:44:54 +0000 2010</created_at>

The output is:

I can parser and print the output perfectly, but when I try to use another file:

<?xml version="1.0" encoding="UTF-8"?>

The output is:

created_at : Sat Jan 02 20:44:54 +0000 2010 id : 7309338854 text : TESTE_AGAIN source : <a href="" href="http://apiwiki.twitter.com/" target="_blank">http://apiwiki.twitter.com/" rel="nofollow">API</a> truncated : false in_reply_to_status_id : (null) in_reply_to_user_id : (null) favorited : false in_reply_to_screen_name : (null) user : geo : (null)

It's almost the same file, only differs at the <statuses> node. I don't know whats is happening. I need help to finish my project...

The program that parses these XML files is:

#include <stdio.h>

#include <libxml/xmlmemory.h>

#include <libxml/parser.h>

void parseCD(xmlDocPtr doc, xmlNodePtr cur)

{

ÂÂ ÂxmlChar* content; ÂÂ

ÂÂ Â Â Â

ÂÂ Âcur = cur->children;

ÂÂ Â Â Â

ÂÂ Âwhile(cur != NULL)

ÂÂ Â{

ÂÂ Â Â Âif(cur->type == XML_ELEMENT_NODE)

ÂÂ Â Â Â{ Â Â Â Â Â Â Â Â Â Â ÂÂ

ÂÂ Â Â Â Â Âcontent = xmlNodeListGetString(doc, cur->xmlChildrenNode, 1);

ÂÂ Â Â Â Â Âprintf("%s : %s\n",cur->name,content);

ÂÂ Â Â Â Â ÂxmlFree(content);

ÂÂ Â Â Â Â Â/*free(content);*/ Â /* windows */

ÂÂ Â Â Â Â Âcontent = NULL;

ÂÂ Â Â Â Â Â}

ÂÂ Â Â Â Â Âcur = cur->next;

ÂÂ Â Â Â}

ÂÂ Â Â Â

}

int main()

{

ÂÂ ÂxmlDocPtr doc;

ÂÂ ÂxmlNodePtr cur;

ÂÂ Âdoc = xmlParseFile("TwittXML.xml");

ÂÂ Âcur = xmlDocGetRootElement(doc);

ÂÂ Â Â Â

ÂÂ Âcur = cur->children;

ÂÂ Âwhile(cur != NULL)

ÂÂ Â{

ÂÂ Â Â Âif(cur->type == XML_ELEMENT_NODE)

ÂÂ Â Â Â{ Â Â Â Â Â Â Â Â Â Â ÂÂ

ÂÂ Â Â Â Â ÂparseCD(doc,cur);

ÂÂ Â Â Â}

ÂÂ Â Â Âcur = cur->next;

ÂÂ Â}

ÂÂ Â Â Â

ÂÂ ÂxmlFreeDoc(doc);Â

ÂÂ Âreturn 0;

}

Thanks!
