Some kind of diff would be a (hrm..) simple extension of the idea.
I didn't think it would be that interesting, but here it would find a use. (-: I have a too big hobby module already, anyway. :-)
Update: What I meant was, a grep thing which understood XML syntax and e.g. allow one grep pattern over the value of an attribute and another grep pattern over the CDATA for that same element.
I don't really know what would be useful (I don't really need it for what I am thinking of doing) and I doesn't have time now anyway.
