If you're dealing with valid XML, it may be a good idea to parse it
using one of PHP's XML extensions, do the manipulations you want with
DOM/SimpleXML API, and then serialize it back to XML.

preg_replace will only work from the front, although you can use the
$limit parameter to get the "n times" functionality.
