Hi All

I'm new to cocoa and working on an xml parser.
I would like to parse xml files like the following example

<poi>
   <description>bla bla</description>
   <image>imag1</image>
   <url>http://www.blabla.com</url>
</poi>
<poi>
   <description>bla bla2</description>
   <image>imag2</image>
   <url>http://www.blabla2.com</url>
</poi>
<poi>
   <description>bla bla3</description>
   <image>imag3</image>
   <url>http://www.blabla3.com</url>
</poi>

I came up with some code from the apple documentation (http://developer.apple.com/documentation/Cocoa/Conceptual/XMLParsing/XMLParsing.html#/
/apple_ref/doc/uid/10000186), but somehow only the first poi is 
processed. There are no errors or warnings in the code.

Thanks in advance!
