Re: how could i captured selected data of the input ?

You could use XML::Twig to parse the data for you, dumping it into a datastructure. Then you've got easy access to individual elements. If you want to get a snapshot of the output that XML::Twig is giving you, just print the datastructure using Data::Dumper. XML::Simple would do the trick too, but I like the reliability of XML::Twig better. See the POD for information on its simplified interface.

I second the vote for XML::Twig, unless you are already comfortable with some other form of XML querying (like XPath etc.) in which case there are many XML modules on CPAN: http://search.cpan.org/search?query=XML&mode=all
