Come together with the global Drupal community in Rotterdam, 28 Sept – 1 Oct 2026. Sessions, contribution, connection, and Early Bird savings until 8 June.Hi,
I would like to use Magpie instead of Simplepie, because I would like to use productfeeds which are not rss 2.0, atom or other newsfeeds.
I found this code that can help may be:
<?php
/*
* Project: XML for MagpieRSS: a simple RSS integration tool
* File: xml_fetch.inc, a simple functional interface
to fetching and parsing XML
* Author: Bram Brambring <bram@brambring.nl>
* License: GPL
* Script requires an installation of MagpieRSS
* Tested with magpie 1.72
* The lastest version of MagpieRSS can be obtained from:

Is it possible to integrate this code in feedparser?
How can this be done?
