Required Arguments

  • parent: This is an xmlnode that you want to find the child node under.
  • tagName: This is the name of the child node you wish to find (case-sensitive).
  • index: This is the 0-based 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.

If you wanted to find an instructions node in an xml file like this:

<root version="2.0">
      <options>
            <instructions>Start at the beginning and keep going until the end!</instructions>
      </options>
</root>

You could use the following code to print the text in the instructions node to the chatbox:

local rootNode = xmlLoadFile ( "test.xml" )
local optionsNode = xmlFindChild ( rootNode, "options", 0 )
local instructionsNode = xmlFindChild ( optionsNode, "instructions", 0 )
local instructions = xmlNodeGetValue ( instructionsNode )

outputChatBox ( instructions )
