Code Examples

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")
if (not rootNode) then
    return
end


local optionsNode = xmlFindChild(rootNode, "options", 0)
if (optionsNode) then
    local instructionsNode = xmlFindChild(optionsNode, "instructions", 0)


    if (instructionsNode) then
        local instructions = xmlNodeGetValue(instructionsNode)
        outputChatBox(instructions)
    end
end


xmlUnloadFile(rootNode)
