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.

Code: (Plaintext)

I would guess that it might be because you are using the same xmlNodePtr (cur) to go through every item in your xml file.
You could try using an array, like this:

Code: (C)
1	xmlNodePtr cur[3];

and then use a different cur[n] item instead of reusing cur.
Also, it would be easier to use xml properties instead of multiple elements,
for example:

Code: (XML/HTML)
1 2 3 4	<addressbook> <contact lastname="Grey" firstname="Jack" cellphone="03445656565"/> <contact lastname="White" firstname="Mary" cellphone="5656546456"/> </addressbook>

then use

Code: (C)
1 2 3 4 5 6	if(!xmlStrcmp(cur[n]->name, (xmlChar)"contact")) { strcpy(address->lastname, (char)xmlGetProp(cur[n], (xmlChar)"lastname")); strcpy(address->firstname, (char)xmlGetProp(cur[n], (xmlChar)"firstname")); / and so on */ }

Hope this helps you.
