Re: How to parse a xml file using XML::DOM??

You can also use Perl's power to search for a value in a list:

#!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };

use XML::DOM;


my $doc = 'XML::DOM::Parser'->new->parsefile(shift);
say $_->getAttribute('id') for grep 3464 eq $_->getAttribute('sigid'),
    $doc->getElementsByTagName('signal');

If your XML file is really huge, you might need to switch to a pull or SAX parser. I'm not sure whether XML::DOM provides such an interface.

($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord
}map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,

As it says, XML::DOM is not a streaming or event parser, it's a document parser. So, it stores the entire XML in memory and works the tree. Not very useful for the task at hand, is it? :-)	[reply]
