Hi

So, um, why not use those rules? Then work with the resulting hash?

*tip* ?node_id=3989;BIT=XML%3A%3ARules-%3Enew;HIT=xml ... Re: XML::LibXML drives me to drinking

This might be something like what you were attempting

#!/usr/bin/perl --
use strict;
use warnings;
use XML::Rules;
use Data::Dump qw/ dd /;

my $rawxml = q{<?xml version="1.0" encoding="UTF-8"?>
<root>
<summary>
  <item>
    <value>1.0</value>
  </item>
</summary>
<detail1>
  <item>
    <value>2.0</value>
  </item>
</detail1>
<detail2>
  <item>
    <value>3.0</value>
  </item>
</detail2>
<value> 11 </value>
</root>
};

dd( XML::Rules->new( rules => [], )->parse( $rawxml ) );
dd( XML::Rules->inferRulesFromExample( $rawxml ) );
dd( XML::Rules->new( rules => XML::Rules->inferRulesFromExample( $rawx
+ml ), )->parse( $rawxml ) );


my ( $summary, $detail1, $detail2 ) ;

my $xr = XML::Rules->new(
    qw/ stripspaces 8 /,
    rules => {
      'detail1,detail2,item,root,summary' => sub { return; },
      'value' => [
            '/root/summary/item' => sub {
                ( $summary, $detail1, $detail2 ) = (); #reset
                $summary = $_[1]->{_content};
                return;
            },
            '/root/detail1/item' => sub {
                $detail1 = $_[1]->{_content};
                return;
            },
            '/root/detail2/item' => sub {
                $detail2 = $_[1]->{_content};
                warn "$summary $detail1 $detail1\n";
                return;
            },
            sub { die "unexpected 'value' at ".join('/','',@{$_[2]}) }
+,
        ],
    },
);

my $ret = $xr->parse( $rawxml );
dd( $ret );
