Re: XML::Parser - Code Reference Error?

I think you meant..

my $tmp = $parse->parse($address);
[download]

the $parse object needs a method
Also, the parse method seems to return a array reference, not a hash.

use strict;
use warnings;
use XML::Parser;
use Data::Dumper;
my $parse = new XML::Parser(Style => 'Objects');
my $address = "<LOC><HNO></HNO><STN>Eagle Way</STN><MCN>Gotham City</M
+CN></LOC>";
print Dumper $parse->parse($address);
[download]

this produces..

C:\tmp>test.pl
$VAR1 = [
          bless( {
                   'Kids' => [
                               bless( {
                                        'Kids' => []
                                      }, 'main::HNO' ),
                               bless( {
                                        'Kids' => [
                                                    bless( {
                                                             'Text' =>
+ 'Eagle Way'
                                                           }, 'main::C

                                                  ]
                                      }, 'main::STN' ),
                               bless( {
                                        'Kids' => [
                                                    bless( {
                                                             'Text' =>
+ 'Gotham City'
                                                           }, 'main::C
+haracters' )
                                                  ]
                                      }, 'main::MCN' )
                             ]
                 }, 'main::LOC' )

You might want to consider XML::Simple. It has a much simpler interface

use strict;
use warnings;
use XML::Simple;
use Data::Dumper;
my $address = "<LOC><HNO></HNO><STN>Eagle Way</STN><MCN>Gotham City</M
+CN></LOC>";
my $ref = XMLin($address);
print Dumper $ref;
[download]

This produces...

C:\tmp>test.pl
$VAR1 = {
          'MCN' => 'Gotham City',
          'HNO' => {},
          'STN' => 'Eagle Way'
        };

I've never worked with an array reference before. So how would I print the 'Text'=>'Eagle Way' from that array reference? So it looks like this data structure is a multidimensional array? I'm having a hard time understanding it. What does Data::Dumper mean by 'bless'?	[reply]

`my @array = (1, 2, 7, 10); my $array_ref = \@array; print $array[2]; # prints 7 print $array_ref->[2]; # prints 7 (difference is the -> )` [download] bless basically means that it's not just a reference, it's a reference to an object of some class. Read the documentation for Data::Dumper - it's a great tool to see how these complex data structures are built.	[reply] [d/l]

So I'm trying to print from this array reference, but I'm missing something. `#!/usr/local/bin/perl -w use strict; use CGI::Carp qw(fatalsToBrowser); use XML::Parser; use CGI; use Data::Dumper; my $q = CGI->new(); print $q->header(); my $parse = new XML::Parser(Style => 'Objects'); my $address = "<LOC><HNO></HNO><STN>Eagle Way</STN><MCN>Gotham City</M +CN></LOC>"; my $tmp = $parse->parse($address); print $tmp->[0][1];` [download] So I'm taking the array reference created by $parse->parse($address) and storing it in $tmp. Then I'm trying to print from the array reference but I get an error saying that $tmp isn't an array refernce. What am I missing?	[reply] [d/l]

Problems? Is your data what you think it is?
