 LoadXML( )-   You can use the load( ) method of the URLLoader and URLRequest classes to load data of an XML file, text file...When the load event is completed,you can wrap your function call with arguements (to parse mulitple xml files) to a function  .The function also takes the complete load event as its parameter to get the data from it.

ParseXML( )- You can store the data in an XML structure and you can parse it using the children() and attributes() method of XML class.
Do not keep the same name for your xml file and the root tag in it.
