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.

I don’t think domQuery is released. Jack said, “Unfortunately the 0.40 [yui-ext] codebase is still unstable (I am working on it), but you can grab the DomQuery source from here.”
Thanks for the update Rob. I updated the post accordingly.
