/*
XmlSearch v.1.1
Author:Max Garfinkel
Last Revision: 05/07/2007
new methods added
 
Finds and returns attributes and node values from an xml object
 
public function are:
 
matchAttribute(xml:XML, attributeName:String, attributeValue:String):Boolean
returns true if there exists an attribute of attribute name with the value of attribute value in the xml.
 
getAttributes(xml:XML, searchterm:String, attributeName:String, recursive:Boolean):Array
returns array of 0-* elements containing the attributes attributeName, of node searchterm.
If recursive flag is set to false array will be of 0-1 length.
 
getNodeContent(xml:XML, searchterm:String, recursive:Boolean):Array
returns an array of 0-* elements containing the contents of node searchterm.
If recursive flag is set to false the array will be of 0-1 length.
 
getNodeContentXML(xml:XML, searchterm:String, recursive:Boolean):Array
returns an array of 0-* elements containing the contents of node searchterm.
If recursive flag is set to false the array will be of 0-1 length.
The data is returned as xml blocks within the array.
