XPath is a very powerful tool for finding information in an XML document. This function uses PHP code via SmartPill to allow you to use XPath expressions for parsing out values stored in an XML string. If you'd like to know more about XPath, there's a good tutorial here: http://www.w3schools.com/xpath/default.asp.
