extracting href data in XML

kanz0r has asked for the wisdom of the Perl Monks concerning the following question:

hello fellow monks, I am working with XML parser using XML::Twig module and I ran into trouble extracting href or id value.
For example,

-<NBA> 
   <HomeTeam href="Celtics"/> 
   <VisitorTeam href="Bulls"/>
   ........................ 
   <Stadium id="FleetCenter">
</NBA>
[download]

what is right way to extract value within "" and assign $HomeTeam = Celtics, etc...
any assistance would be appreciated, thanks!

Here is a example. Remember that perl is casesensitive. use strict; use warnings; `use strict; use warnings; use XML::Twig; my $tw = XML::Twig->new( TwigHandlers => { 'NBA/HomeTeam' => \&nba } ) +; $tw->parse(<<__XML__); <NBA> <HomeTeam href="Celtics"/> <VisitorTeam href="Bulls"/> <Stadium id="FleetCenter">blabla</Stadium> </NBA> __XML__ $tw->flush; sub nba { my ( $twig, $nba ) = @_; $nba->set_att( href => 'MyHomeTeam' ); $twig->flush; }` [download] Boris	[reply] [d/l]

still can't figure one thing out, why i can't use the following code just to get the data "Celtics" `$hometeam -> ('att') -> ('href');` [download]	[reply] [d/l]

Because `att` is a method, that you call with the syntax `$hometeam ->att('href');`?	[reply] [d/l]
