This rules out XML::Rules for things like: "eliminate all sections 
marked with attribute "klass" whose value is 12.

Processing XML (or in my case, XHTML) is not always based on the gi.

Whereas with treebuilder, I can do

my @node = $tree->look_down(klass => 12);
$_->delete for @node;


if-then is my last resort for complexity management.
