Hi,

Trying this but only "aaa" outputs not "bbb". What's fix? I'm new to
XML and Perl - help appreciated.

xml file:

<?xml version='1.0'?>
<config>
<attrbs>
<attrb>aaa</attrb>
<attrb>bbb</attrb>
</attrbs>
</config>

perl file:

#!/usr/bin/perl -w
use strict;
use XML::Twig;

my $twig= XML::Twig->new( twig_roots => {'/config/attrbs' =>
\&do_attrb});
$twig->parsefile( "xmlt1.xml");
$twig->purge();

sub do_attrb {
my($a1) = $_->find_nodes("attrb");
print $a1->text, "\n";
}

output:

aaa

find_nodes returns a list of nodes, so the first line here
assigns the first element of that list to $a1.

I think you want
my @attrb= _->find_nodes("attrb");
print map { $_->text } @attrb;

Does that help?
