Looking at the documentation of XML::DOM, it shows the use of `->getElementsByTagName`. The simplest approach would then be something like: `my $signals = $doc->getElementsByTagName('signal'); my @by_id = grep { my $sigid= $_->getAttributeNode('sigid'); if( $sigid ) { $sigid == 3464 } else { 0 # no sigid attribute, no match } } map { $signals->item($_) } 0..$signals->getLength()-1` [download] I still recommend using an XPath query.
