    Using XML::Compare: 
    #!/usr/bin/perl 

use strict;
use warnings;
use XML::Compare tests => 2;

my $xml1 = '<xml><abc> abcd </abc></xml>';
my $xml2 = '<xml><abc> abcd e </abc></xml>';

my $same = eval { XML::Compare::same( $xml1, $xml2 ); };
if ($same) {
    print  "same" ;
}
else {
    print "different: $@";
}

    I usually just run 
    xmllint --c14n "$xml" | xmllint --format -

    on both files and use standard diff on the results. But it really depends on the type of XML files and typical changes that occur in them.
