XmlFindSubNode

Description

This function returns a named sub node of a particular XML node.

Syntax

xmlnode xmlFindSubNode ( xmlnode parent, string subnode, int index )

Required Arguments

• parent: This is an xmlnode that you want to find the subnode under. This could be a node returned from another call to xmlFindSubNode.
• subnode: This is the name of the subnode you wish to find.
• index: This is the index of the node you wish to find. For example, to find the 5th subnode with a particular name, you would use 4 as the index value. To find the first occurence, use 0.

Example

If you wanted to find the 'instructions' node in a map file like this:

<map>
      <options>
            <instructions>Start at the begining and keep going until the end!</instructions>
      <options>
</map>

You could use the following code:

maproot = getLoadedMapXMLRoot ();
optionsnode = xmlFindSubNode ( maproot, "options", 0 );
instructionsnode = xmlFindSubNode ( optionsnode, "instructions", 0 );
