Recently, David Smith wrote about querySelectorAll support in upcoming version of WebKit (the rendering engine for Safari, amongst others).

Basically, querySelectorAll is a way to get the document to evaluate a CSS selector, and then return the matching node(s). Having native support for this is no less than fantastic!

Example code can look like this:

I’ve done some coding and performance tests, and it even surpasses cleverly crafted XPath selections. My take is that every web browser implementer should implement this. Now!

Hold off on Firefox 3 and Opera 9.5, this feature is to good to wait longer for.
