>From reading the spec, it wasn't immediately clear to me which of the following two cases applies to element.querySelectorAll (and similarly to element.querySelector): 1. The nodes returned are the nodes that match document.querySelectorAll AND are contained within the subtree rooted at the element. 2. The nodes returned are the nodes that match the group of selectors if the selection algorithm is run only on the subtree rooted at the element. Put as an example (which is probably clearer), with the following document: <html> <body> <div id="foo"> <a href="javascript:alert(document.getElementById('foo').querySelector('bod y a'));">test</a> </div> </body> </html> If case (1) applies, then the querySelector should match the anchor tag and the dialog should show [object HTMLAnchorElement]. If case (2) applies, then since there is no "body" tag within the <div id="foo">, nothing will match and the alert dialog will show null. None of the browser versions I currently have installed support querySelector yet, so I couldn't check against their implementations. Any clarification would be appreciated.
