.filter() no longer modifies the object that calls it

Imagine a table of form fields. I've been extracting the data from these fields by using .filter("[@name^='foo']") to get a particular row, and then looping over .filter("[@name$='bar']") to get the column. With the original version of jQuery, I have to do .end().filter("[@name$='bar2']") or I get an empty set. With the updated jQuery, that .end() returns the Document, which causes the chained .filter() to be meaningless.

If this turns out to be a problem that jQuery Update isn't meant to fix, I'd love to hear an alternate solution to my problem that works with or without it.
