You could probably do some sort of custom tag. First, get the
location of <body, then look for the next instance of > and replace
everything up to that point with nothing. Then look for </body and
replace everything from there to the end 'len()' of the template with
nothing. Then I'd replace all line breaks with nothing, and look for
any occurrence of <br> and replace with a single line break and all
instances of <p> and replace with a double line break. Then you'd
have to systematically loop though and look for any other instance of
< and the following occurrence of > and replace that string with
nothing. You could also replace all tabs with nothing, maybe replace
all instances of (space space) with space | space), then delete all
instances of (| space) which should leave the template with all
single spaces. You could also look for instances of & then a
following instance of ;, look to see if there are any spaces between
the two and if not. it should mean it's a character code, and delete
the string.
Once all that is done, you should have a reasonable facsimile of what
the page would have looked like. If you're trying to keep the
formatting, lord knows what you'd have to do with tables and forms
though.
