/**
 * Convert XML Element To Array
 *

 * as a nested associative PHP array, to make it easier to work with. It's called recursively
 * to deal with an entire document. Adapted from
 * http://www.ibm.com/developerworks/xml/library/x-xml2jsonphp/
 *
 * @param string $xml_element A single element, possibly containing children
 * @param int $recursion_depth The depth of the call stack
 * @return array All the tags in the XML element converted into an associative array
