Remove Tags Except...
Instructions: create an otherwise empty page (with header and body) with a table with 1 column. In that column, type tagnames. These tagnames are the tagnames you want Remove Tags Except to skip when stripping HTML from the current document. Save that file, then open this command and choose (via CHOOSE) and load that file via the LOAD button. Hit GO and the page will be stripped of all tags except the ones you specified. You can create multiple exclusion files which you might use for differing projects. This will NOT strip out comments as Clean Up HTML does that.
