The expressions in XML::LibXML and XML::XPath are XPath expressions. They
are very powerful in that you can generally craft an XPath expression to get
exactly what you want, making most extractions a one-liner.
Your code loops around a 'product-announced' element, which doesn't exist in
your file. Does that have something to do with it?
Since you say you're new to XML parsing, perhaps you'd like to see an
example of an alternate solution. The following is XML::LibXML code, and
XML::Xpath code would be vi
