I actually thought that was the case now, but it's still faster not to perform additional checks if not needed. Plus, what happens if you have: <div id="bam" /> <span id="bam" /> What if you need to retrieve the span tag? If it's checking #bam first, won't it only find the <div /> element? (And yes, I know the HTML spec says that IDs should be unique, but occasionally you're dealing w/dynamically generated server content that's out of your control.) -Dan
