David, That's a wonderful example for me and for the knowledge base in this group. I learnt several things about the DOM as well.
The loop I used in my second post to this thread (http://tech.groups.yahoo.com/group/svg-developers/message/57931) ran surprisingly fast for 3000 nodes.

Then you could just merely toggle the visibility of that group. This would save during run-time but cost at startup time. If you had more than two functions, like say dozens, then this technique would become unwieldy. > > Hope this helps, > David > > [Non-text portions of this message have been removed] > ----- To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" ---- Yahoo!
