About XML::Simple—In XMLin

• Use the RootName option to set the root to AdXML. I'll assume you set the ref to the root to $AdXML.
• Use the ForceArray option on Preroll, Midroll and Postroll.
  • You probably want

    use XML::Simple;
    my $xs = XML::Simple->new;
    my $AdXML = $xs->XMLin($adfile, ForceArray=>1, RootName=>'AdXML');
    [download]

  That way, no matter whether there's one or some other number of instances, $AdXML->{Midroll} etc. will always be an array ref (not a hash ref). (not tested.)
• With this approach, the number of ads, the arbitrary order of the ads, and the arbitrary order of their attributes is not an issue.
• If you didn't know about ForceArray, you probably don't know about KeyAttr either. Read the docs on it; as they say, it's important and you'll want to understand it.
