Re: Struggling with XML

This does the trick...

use 5.010;
use Data::Dumper;
use XML::LibXML 1.70;

my $xml = XML::LibXML->load_xml(IO => \*DATA);
my @results;
foreach my $dict ($xml->findnodes('//dict'))
{
    my $key = $dict->getAttribute('key');
    next unless $key ~~ [qw( subnet gateway cidr netmask )];
    push @results, {} if $key eq 'subnet';

    my $value = $dict->findvalue('.//value');    
    $results[-1]{ $key } = "$value";
}

print Dumper \@results;

tobyink thank you very much. There's a couple of things I'll need to study to ensure I've fully understood everything but I think I'm pretty much there with you assistance. Much appreciate all your input.	[reply]

This I like though due to the fixed stack we have to work with I cannot use Perl later than 5.8.8 and also cannot use LibXML 1.70. I appreciate that is a whole topic of conversation in itself but those are the boundaries. I do appreciate the help though as this is very helpful in getting me going with Perl. However, I've done a little bit with the code to make it work with 5.8.8 and I'm almost there but currently only outputting subnet and I need gateway, cidr and netmask too. ... my $ua = LWP::UserAgent->new(); my $req = HTTP::Request->new('GET', $url); my $res = $ua->request($req); my $parser = XML::LibXML->new(); sub smart_match { my ($target, $param) = @_; if (ref $param eq 'Regexp') { return ($target =~ qr/$param/); } else { return ($target eq $param); } } my $xml = $parser->parse_string( $res->content() ); my @results; foreach my $dict ($xml->findnodes('//dict')) { my $key = $dict->getAttribute('key'); #next unless $key eq [qw( 'subnet', 'gateway', 'cidr', 'netmas +k' ) ]; next unless smart_match( $key, qw( subnet gateway cidr netmask + ) ); print Dumper($key); push @results, {} if $key eq 'subnet'; my $value = $dict->findvalue('.//value'); $results[-1]{ $key } = "$value"; } print Dumper \@results; [download] Which outputs: `$VAR1 = 'subnet'; $VAR1 = 'subnet'; $VAR1 = 'subnet'; $VAR1 = 'subnet'; $VAR1 = 'subnet'; $VAR1 = [ { 'subnet' => '10.11.14.0' }, { 'subnet' => '10.11.15.0' }, { 'subnet' => '10.15.8.0' }, { 'subnet' => '10.7.17.224' }, { 'subnet' => '10.11.24.0' } ];` [download]	[reply] [d/l] [select]

Meh... I replied to the wrong node. See Re^2: Struggling with XML. `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply]
