Here is a perl program that does a similar thing:
(what I've done is strip out the #! /usr/bin/env perl and pasted the 
rest here. When I have tried to attach perl scripts in the past, they 
get scrubbed away)
****

use XML::Parser;

$parser = new XML::Parser( Style => 'Tree' );
my $tree = $parser->parsefile( shift @ARGV );

use Data::Dumper;
print Dumper( $tree );

****
This creates an output similar to what you've done. Since it's a perl 
program, it could be modified to further parse out details. This output 
is typically many lines long.
