php - What to use for XML parsing / reading in PHP4

Question

Unfortunatly I have to work in a older web application on a PHP4 server; It now needs to parse a lot of XML for calling webservices (custom protocol, no SOAP/REST);

Under PHP5 I would use SimpleXML but that isn't available; There is Dom XML in PHP4, but it isn't default any more in PHP5.

What are the other options? I'm looking for a solution that still works on PHP5 once they migrate.

A nice extra would be if the XML can be validated with a schema.

Answer 1

There is a simpleXML backport avaliable: http://www.ister.org/code/simplexml44/index.html

If you can install that, then that will be the best solution.
