Hey Eric
Thanks very much for the explanation.. I'll play with the Selector class..
Cheers

Gotcha, just misunderstood your question.
The search applies to the current document. If you want it to only
apply to a portion of the document you would need to put an identifier
on that portion and prepend that identifier to your search criteria.
You might be able to use a DOM fragment but you would have to use the
Selector objects directly instead of using the $$() function. So
something like:
s = new Selector('.item');
items = s.findElements(dom_fragment);
I have never tested the above code but it seems it should work. The
only catch is that using the selector object will only allow you to
use the basic selector syntax. You cannot specify element
relationships. For example the following would not work:
s = new Selector('#news .item');
news_items = s.findElements(dom_fragment);
If you want to specify relationships and use a dom_fragment you would
probably need to do something like this (borrowed from the $$()
implementation):
function $$WithFragment(expression, fragment) {
return expression.strip().split(/\s+/).inject(
[fragment], function(results, expr) {
var selector = new Selector(expr);
return results.map(
selector.findElements.bind(selector)).flatten();
});
})
Of course none of the code is tested but that should give you the
general idea.
