View Full Version : Node emptier

02-10-2004, 11:03 PM
From a different challenge involving time-sensitive text, I came up with this little goodie.

function clearNode (node) {
while (node.childNodes.length > 0) {
return node;

I'd like to make this a method of the Node prototype, but I haven't figured out *quite* how to do it yet. Comments? Improvements?

Didn't normalise have the irritating property that it crashes some version of ie? I think I remember something like htat happening. Anyway, the Node object is only exhibited by Opera and Mozilla for the moment, so you'de not going to find a way to do that. Make it a global function instead.

Are you looking to remove useless whitespace text nodes from a node tree? Cos Alex Vincent wrote a nifty method for that - http://www.codingforums.com/showthread.php?s=&threadid=7028

Except don't let it run in mac/ie5, because in that browser HTML structures become unstable when stripped of whitespace.
