/*
* _xml2array - an abstraction layer on xml_parse_into_struct that returns a
* nice nested array. based on dudus at onet dot pl's:
* http://www.php.net/manual/en/function.xml-parse-into-struct.php#49154
* changes made are:
* - nicer formatting of code
* - set xml parser options to make array keys lowercase / ignore whitespace
* - stuffed attributes into a child array of the same name
**/
/*
* @param: $raw_xml - string containing xml to feed into xml_parse_into_struct()
* returns nice nested php array containing xml data.
