This function returns a named child node of an XML node.
Syntax
xmlnode xmlFindChild ( xmlnode parent, string tagName, int index )
OOP Syntax Help! I don't understand this!
- Method: xmlnode:findChild(...)
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.
Returns
Returns an xmlnode if the node was found, false otherwise.
Example
Click to collapse [-]
ServerIf 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 ) xmlUnloadFile(rootNode) outputChatBox ( instructions )
