G'day Roboz,
Firstly, the data structure you present is invalid. In the code below, I've added a closing brace to 'Mineral' => { .... Also, you show $Var1 as being a reference to a hashref: I don't know if that's correct or another typo - the following code assumes it is correct.
This code shows how you might go about achieving what you're after. I'll leave you to make adjustments for whatever typos may exist.
#!/usr/bin/env perl
use strict;
use warnings;
my $SOAPresult = \{
'Thing' => [
{
'Animal' => {
'ThingName' => 'Dog',
'ThingID' => '123'
}
},
{
'Veg' => {
'ThingName' => 'Carrot',
'ThingID' => '42'
}
},
{
'Mineral' => {
'ThingName' => 'Talc',
'ThingID' => '007'
}
}
]
};
my $SOAPresult_deref = $$SOAPresult;
my @types = qw{Animal Veg Mineral};
for my $type (@types) {
foreach my $e ( @{ $SOAPresult_deref->{Thing} } ) {
next unless exists $e->{$type};
print "Wildcard = $type\n";
print "$e->{$type}{ThingName}\n";
}
}
Output:
$ pm_ref_var_access.pl
Wildcard = Animal
Dog
Wildcard = Veg
Carrot
Wildcard = Mineral
Talc

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
