processed html

I am interested in getting the processed html source (after all scripts were processed).
For example if the html source contained this section

<script>
var query = window.location.search.substring(1);
var ListComp = getQueryVariable(“ListedComp”, query);
if(ListComp == null) {
ListComp=’All’;
}
var strurl = ‘/about/listed/lc_B.html?ListedComp=’+ListComp;
document.write (“<a href=”+strurl+”>B</a> &nbsp;”);
</script>

I want this to be replaced by what is actually in the document (just the <a> tag).

is anyone familiar with such a tool ?
it seems as if Gecko & MSHTML should be able to do this however i did not see any documentation regarding this.

thanks,
elewinso.
