I understand you've got your script working but I just wanted to point out a potential problem with this line:

my $config = XMLin();

Calling XMLin() with absolutely no parameters is a bit of a 'red flag'. In your case, you want the XML file to be found automatically, so leaving the first parameter undefined is OK; but you're expecting the <profile> elements to be 'folded' into a hash keyed on the contents of the 'name' attribute. Unfortunately, if config file is edited and there's only one <profile> element in it, things will go horribly wrong. I'd recommend:

my $config = XMLin(undef, 
  keyattr    => { profile => 'name'}, 
  forcearray => [ 'profile' ],
);
