I have a div tag with an id of mainBlock. How can I remove everything inside the DIV tag using DOM and javascript? Thanks.

or....

Iterate through all the children removing each from the parent.

The former is easier and liklely quicker.

Hi Bear,
Thanks that worked fine. I thought for sure I had tried that though earlier and then (after thinking it failed) started trying other things. Anyways thanks again.

That div tag I was talking about. Sometimes it may or may not be on the page what is the easiest/best way to determine it's on the page or not? Thanks.
