lines 100,101,102 have to do with a cache file, if you want to use a cache file you must create an xmlcache directory and point the script to it in the line (101)
Text Formatted Code
$cacheFile = fopen("xmlcache/".$cacheName,"w");
Alternatively you can just specify the first two parameters when you call parseurl!
eg.
Text Formatted Code
parseURL("http://www.flamingbird.com/public_html/backend/geeklog.rdf",10,false);
Hope this helps
