I got this example from Beginning PHP 4. Unfortunately, I cant get to
wrox's site to see if there were any errata updates for this piece of
code, but for the life of me, I dont know whats wrong with it. All its
displaying is '-'. If anyone could direct me to where its broken, Ill
be very grateful..

<?php
if (!($fp = fopen("http://freshmeat.net/backend/fm.rdf";, "r")))
die("Cant fetch");
$item_counter = 0;
$in_item_tag = 0;

$fm_headline_data = array();
function startElementHandler($parser, $element_name, $element_attribs) {
global $item_counter, $in_item_tag, $fm_current_tag_state,
$fm_headline_data;
