Seems like if you have to do huge DOM queries on every page, maybe the app could use a redesign/optimization in general. XPath looks good, but you could also just have your server-side code spit out an array of IDs in a script element and loop over that with getElementById. Basically move the hassle of finding certain DOM elements onto the server's shoulders where you've got plenty of speed. I guess I don’t understand the big need for speed in this dept.

The faster way is to use document.all. Most of the browsers implemented <b>document.all</b> now. Please check the fastness by yourself with the following link: http://www.geocities.com/keelypavan/DOMFasterMethods.html . Please click on the second button first as Alex's method is resetting ids. I tested in IE 6, Firefox 1.5, opera 8.54 and in all these browsers document.all method took almost 0ms. I know it's not a W3C standard but when all the browsers implemented that, I don;t see any other reason why we should stop using that. Pavan Keely Hi all,
