Honestly, I think the simplest solution is XML::XPath.
my $xp = XML::XPath->new( ioref => $input );
my $mp = $xp->find('/meta-parameter');
for my $n ($mp->get_nodelist) {
if( $xp->findvalue('@type' => $n) eq "stored-procedure" ) {
warn "found: " . $xp->findvalue( '@id' => $n );
}
}
For regulars of this type, I usually multi-stage it so I can be sure I matched the right thing.
if( m/<([^>]*meta-parameter[^>]*stored-procedure[^>]*)>/ ) {
my $tag = $1;
if( $tag =~ m/id=['"](.+?)['"]/ ) {
my $id = $1;
# argueably not the most robust thing in the whole wide world,
# but you get the idea
}
}
