[xml] libxml2 -- can't get value of the node

[rachit goel <panthers0072001 yahoo co uk>]

hi 
 
 i am using  "xmlReadFile(filename, "utf-8", XML_PARSE_DTDVALID )"  to read a xml file and then traverse the tree. This is what my aml file looks like
 
 <document>
 <name>Windows</name>
 <date>Menus and Toolbars</date>
 <descrip>Customize the appearance of toolbars and menubars in applications</descrip>
 </document>
 
 now when traversing the tree to get the values of the nodes in name , date , descrip i use this code 
 
 static void
 print_element_names (xmlDocPtr doc,xmlNodePtr a_node, unsigned char** values , int *char_count)
 {
     xmlNodePtr cur_node = a_node;
     xmlChar *nam = "name" ;
     xmlChar *dat = "date" ;
     xmlChar *des = "descrip" ;
     xmlChar *docu = "document" ;
      gint count
 ;     
 
     count = 1 ;
 
 
     do
     {
            if (cur_node->type == XML_ELEMENT_NODE) 
             {
                     g_printf("\n 1 node : %s  value[1] = %s  , \n size = %d \n\n ", cur_node->name ,  xmlNodeGetContent(cur_node->children) , 0);//char_count[count]);
 
                      if(xmlStrcmp(cur_node->name,docu) == 0)
                     {
                             print_element_names (doc, cur_node->ch
 ildren ,
 values , char_count) ;
                     }
                     else
                     {
   116:                          values[count] = xmlNodeGetContent(cur_node->children);
                             char_count[count] = xmlStrlen((xmlChar *)values[count]) ;
                             g_printf("\n2  node : %s  value[1] = %s  , \n size = %d \n\n ", cur_node->name ,  values[count] ,
 char_count[count]);
                                 count = count + 1 ;
                             }
             }
     cur_node = cur_node->next ;
     }while(cur_node != NULL) ;
                 printf("\n print: after for\n");
 }
 
 the printf's are just for debugging. What actually happens is that in first recursiive call at cur_node->name = "name"
 values[count] = xmlNodeGetContent(cur_node->children); 
 (this is line no. 116 in my file)
 gives me an error 
 
 0x08049d2e in print_element_nam
 es
 (doc=0x8acd9a0, a_node=Variable "a_node" is not available. 
 ) at interface.c:116
 
 the code has been taken from tree example itself.
 
 can u plz tell me what is wrong here and how can i correct it thanks.
 Also is there a better way of getting the values of the node.
