Hello - Below you'll find a Perl script and XML code. The .pl file reads from the .xml file, then turns the XML info into an HMTL document. The script works, but it works too well. I'm trying to extract the information from between the <! CDATA [ ] > tags. But instead it retrieves everything (the <!CDATA[ ]> and the info within it). How can I have the script pull just the info from within the brackets?

XML: 

<!CDATA[ Test tittel ]> - <!CDATA[ test ingres ]> - <![CDATA[ http://w
+ww.test.com/test ]]>
