Jack Slocum who manages a great extension library for Yahoo! UI has released is working on a new library for CSS/XPath selection of the DOM named DomQuery. The first figures says it is fast, extremely fast.

To make it even more interesting, jQuery has released a new version of the library where api-size and speed has been the main focuses, but it still doesnt match DomQuerys speed. DomQuery made me start looking into Yahoo UI. Its a good competition benefitting all of us working with interface development. I am sure the jQuery community will make the best out of this competition. There is already a debate between John Resig and Jack Slocum about the results and how to interpret them.
