note 49334 added to function.xml-parse-into-struct

This is my first time contributing but I found all the examples either didn't work or were beyond my comprehension. I also wanted to maintain the XML multi-dimensionality so I could do loops based on keys I was expecting rather than numbers or some other whatnot. This script is probably way inefficient, but should give you a multidimensional array with a depth that will match the XML source. Great for situations when you aren't sure what you'll be getting back. Its also only based on the values array of xml_parse_into_str() using the 3 tag types (open, complete, and close) -- hopefully it will make more sense to other noobs. Basically it just constructs a string ($php_prefix) that is tweaked if it hits an "open" or "close" tag and evaluated if it hits a "complete" tag.
