Re: PHP & XML Parsing

Hello Fabian, This was very helpful. Thanks for letting me know about this little glitch. It almost resolves the problem that I was having. Now I no longer get xml errors. However, I'm not able to output the XML either. Any suggestions would be appreciated. The updated code is available here: http://www.airdiv-cupe.org/portal/newsfeed_new_parser.php And I've included the full script in the email (at the very bottom of this message). Thanks.

Hello, In looking for a good script to parse XML files I stumbled across the

following

tutorial (which looks very good): http://www.wirelessdevnet.com/channels/wap/features/xmlcast_php.html I have set this script up here: http://www.airdiv-cupe.org/portal/newsfeed_new_parser.php and I keep getting the following error (even after making a number of

changes):

XML error: not well-formed at line 16 And I'm not sure how to troubleshoot this problem. I'm assuming that it is referring to line 16 on the XML file, in this

case:

http://cupe.ca/xml/cupenews.rdf My parsing definitions are as follows $itemTitleKey = "^rdf^item^title"; $itemLinkKey = "^rdf^item^link"; $itemDescKey = "^rdf^item^description"; Any help would be appreciated.
