This looks familiar ... ;)

Have been introduced to Data::Dumper yet? Here is what it makes of the XML 'tree' that is built by XML::Simple: 
use Data::Dumper;

my $data = do {local $/;<DATA>};
my $xml  = XMLin($data);

print Dumper $xml;

Yields: 
$VAR1 = {
   'label' => 'gene_of_interest',
   'id' => '3'
};
From this we see that label and id are the 'top level' keys, there is no 'gene' key. However, had the XML been a bit more proper ... 
use strict;
use warnings;
use XML::Simple;

my $data = do {local $/;<DATA>};
my $xml  = XMLin($data);

# ... and you use the correct syntax ;)
print $xml->{gene}->{id}, "\n";
print $xml->{gene}->{label}, "\n";

__DATA__
<?xml version="1.0" ?>
<genes>
<gene id = "3" label = "gene_of_interest" />
</genes>

Then all is well. :)
