[Glade-users] libxml and treeview - how to read in more than one entries from an xml file

[atmadarshini_dd at yahoo.com (Atmadarshini devi dasi)]

Hi there

I am working with glade, gtktreeview and libxml. What i am trying to do is that from an xml file, I am trying 
to put things into my treeview. My treeview for instance has three columns such as Lastname, Firstname, 
cellphone. 

my xml file looks like this:

<addressbook>
    <contact>
        <lastname> Grey </lastname>
        <firstname> Jack </firstname>
        <cellphone> 03445656565</cellphone>
    </contact>
     <contact>
         <lastname> White</lastname>
         <firstname>Mary </firstname>
         <cellphone> 5656546456</cellphone>
     </contact>
</addressbook>

Now I want for instance "Grey, Jack and 03445656565" to come into the first row and "White, Mary and 
5656546456" to come into the second row.

I am able to get "Grey, Jack and 03445656565" into the first row but when i try for the second row, "Grey, 
Jack and 03445656565" gets repeated instead of the second contact being read.

How do i go about doing that....I think i need some kind of loop but I am not sure. I am attaching my code 
below. please tell me what code i can use to be able to access the other contacts in the xml file and then be 
able to show them in the tree view. All help will be greatly appreciated.

/*this function belows gets the contacts from the addressbook*/

int addressbook_get_addresses_from_xml_file(char *filename)
{  
     xmlDocPtr doc;
    xmlNodePtr cur, child;
    
address = (AddressBook*)malloc(sizeof(AddressBook));    


    if (filename == NULL)
        filename = "addressbook.xml";

    /* Parse our addressbook file */
    

    if(!(doc = xmlParseFile(imsua_addpath(filename))))
    {
        g_warning("Error opening addressbook file: %s", imsua_addpath(filename));
        xmlFreeDoc( doc );
        return FALSE;
    }

    if(!(cur = xmlDocGetRootElement(doc)))
    {
        g_warning("Addressbook document has no root element");
        xmlFreeDoc( doc );
        return FALSE;
    }

    if(xmlStrcmp(cur->name, (const xmlChar *) "addressbook" ))
    {
        g_warning("XML document of the wrong type, root node != addressbook");
        xmlFreeDoc( doc );
        return FALSE;
    }

    cur = cur->xmlChildrenNode;
    

    /* Traverse through document looking for our addressbook */
    while(cur)
    {
        if (cur->type == XML_ELEMENT_NODE)
        {    
            if(child = cur->xmlChildrenNode)
            {
                if(!xmlStrcmp(cur->name, (const xmlChar *)"contact")){

                cur = cur->xmlChildrenNode;

                strcpy(address->lastname, child->content);
                printf("Last Nmae: %s\n", address->lastname);
                }

                    //address->homephone = atoi(child->content);
