If I have no need for the "goodies" of other XML parsers, I use XML::Bare.
It's fast, to the point and doesn't try to do too much.

See http://darkpan.com/files/xml-parsing-perl-gripes.txt for my rant on the topic.

That said,

% perl -MXML::Bare -le'
   $x   = XML::Bare->new(file => $ARGV[0]);
   $xml = $x->parse;
   print $_->{hash}->{value} for @{ $xml->{changelog}->{patch} };
' test.xml

I think the above is close to what you need?
