[Glade-users] reading from an xml file into text entry boxes

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

Hi guys

I am having a problem. I am a new learner trying to program using C and create my user interface using glade. 
I have lets say a window with 2 text entry boxes for now. I have an xml file and I want to read the entries 
from the xml file and place them into the text entry box. How do i go about doing this? I am able to read 
from the xml file and place the entried on the console window but when i try to read them into the text entry 
box, i get an error. I am not sure how to assign the values from my xml file to the text entry boxes. Am 
pasting my code below.

XML file

<addressbook>
  <lastname>Dasi</lastname>
  <firstname>Atma</firstname>
</addressbook>

so when i click a button, i want to see for instance Dasi in the first textbox and Atma in the second text 
box. I have named my first text box as lname_entry and second textbox as fname_entry.

my code is as follows:

# include "includes.h"
#include "addressbook.h"
AddressBook *address; //AddressBook is a structure
GtkWidget *address_window; //address_window is the window with the textboxes

void addressbook_set_addresses_dialog()
{
    lname_entry_widget = lookup_widget(GTK_WIDGET(address_window), "lname_entry");
        GtkWidget *fname_entry_widget = lookup_widget(GTK_WIDGET(address_window), "fname_entry");
gtk_entry_set_text(GTK_ENTRY(lname_entry_widget), address->lastname);
gtk_entry_set_text(GTK_ENTRY(fname_entry_widget), address->firstname);
}
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 *)"lastname")){
                    strcpy(address->lastname, child->content);

                    printf("Last Name: %s\n", address->lastname);
   
}

                if(!xmlStrcmp(cur->name, (const xmlChar *)"firstname")){
                    strcpy(address->firstname, child->content);

                    printf("First Name: %s\n", address->firstname);}

            }

        }
        
        cur = cur->next;
    }

  
    return TRUE;
}

I call addressbook_get_addresses_from_xml_file("addressbook.xml") when the button is clicked and i call 
addressbook_set_addresses_dialog() when the window is activated to show

I am not sure what the difference between gtk_entry_set_text and gtk_entry_get_text is. Can someone please 
help? I am in need of urgent help...

Thanks
