Help in XML::Simple

I'm looking for a simple way to process results returned from a
website via XML. I was thinking XML::Simple should be simple... but
apparently I'm even simpler than it is!


I'm having trouble figuring out how to get at the four items it
returns. Looks like $tags contains a hash which is actually a data
structure named $VAR1, which appears to define a hash, but how do I
make it work? It looked empty, but Dumper shows the contents and they
look like exactly what I want... but how do I access it???



use XML::Simple;
use Data::Dumper;
$content="
12
Decline

RE-PRESENTED CHK
99220
";
$tags = XMLin($content);
print "\n\nDumper:\n";
print Dumper($tags);



RESULT
______________________________ Results:


Dumper:
$VAR1 = {
'authcode' => 'LREADY USED',
'pnref' => '99220',
'respmsg' => 'Denied',
'result' => '12'___
'result' => '12'
};

You should have here:

use strict;
use warnings;

> use XML::Simple;
> use Data::Dumper;
> $content="

Change the above line to:

my $content ...

> 12
> Decline
>
> RE-PRESENTED CHK
> 99220
> ";
> $tags = XMLin($content);

Ditto:

my $tags = ...

This is not what I get when I run your program. You have changed the
authcode from 'LREADY USED' to 'RE-PRESENTED CHK', and I do not get two
'result' entries. Please post exact code and output from your program
so you don't confuse those trying to help you.

The $VAR1 is a name picked by the Data::Dumper module. This is
explained in the documentation for Data::Dumper, although perhaps not
so clearly as it could be. Have you read the documentation for
Data::Dumper? If you want a more explicit output format, you can use
the following:

print Data::Dumper->Dump([$tags], [qw(tags)]);

as explained in the documentation for Data::Dumper.

XMLin returns a reference to a hash. There are examples of how to
access the data in the documentation for XML::Simple. Have you read the
documentation for XML::Simple?

As an example in your case, the authcode entry is ${$tags}{authcode}.

Or, since that syntax makes me wince, $tags->{authcode}
