XML::Simple is your friend: 
my $ref = XMLin([<xml file or string>] [, <options>]);

 Never mind, that won't work from STDOUT, you'll have to tie first, as explained in the RRDTool::OO documentation:

Dumps the RRD in XML format to STDOUT. If you want to dump it into a file instead, do this: 
    my $pid;

    unless ($pid = open DUMP, "-|") {
        die "Can't fork: $!" unless defined $pid;
        $rrd->dump();
        exit 0;
    }

    waitpid($pid, 0);

    open OUT, ">out";
    print OUT $_ for <DUMP>;
    close OUT;

Just replace the last couple of lines by 
    use XML::Simple;
    my $data = join '', <DUMP>;
    my $ref = XMLin($data);

and you'll have the data structure in $ref.
