in reply to 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; __DATA__ <root> <dict key="status"> <value>success</value> </dict> <dict key="data"> <list> <dict key="subnet"> <value></value> </dict> <dict key="gateway"><value></value> </dict> <dict key="cidr"><value></value> </dict> <dict key="netmask"><value></value> </dict> <dict key="subnet"><value></value> </dict> <dict key="gateway"><value></value> </dict> <dict key="cidr"><value></value> </dict> <dict key="netmask"><value></value> </dict> <dict key="subnet"> <value></value> </dict> <dict key="gateway"> <value></value> </dict> <dict key="cidr"> <value></value> </dict> <dict key="netmask"> <value></value> </dict> <dict key="subnet"> <value></value> </dict> <dict key="gateway"> <value></value> </dict> <dict key="cidr"> <value></value> </dict> <dict key="netmask"> <value></value> </dict> <dict key="subnet"> <value></value> </dict> <dict key="gateway"> <value></value> </dict><dict key="cidr"> <value></value> </dict><dict key="netmask" ><value></value> </dict> </list> </dict> <dict key="exitCode"> <value>0</value> </dict> </root>

    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;
    Which outputs:
    $VAR1 = 'subnet'; $VAR1 = 'subnet'; $VAR1 = 'subnet'; $VAR1 = 'subnet'; $VAR1 = 'subnet'; $VAR1 = [ { 'subnet' => '' }, { 'subnet' => '' }, { 'subnet' => '' }, { 'subnet' => '' }, { 'subnet' => '' } ];

      Meh... I replied to the wrong node. See Re^2: Struggling with XML.

      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.
