Emile,

> replaced = target.replace(stripped,"<html>%s</html>" % stripped)

Brilliant! That's just the type of clever solution I was looking for.

Thank you!

Malcolm

I'd do it this way:

target = '      spam and eggs      '
stripped = target.strip()
replaced = target.replace(stripped,"<html>%s</html>" % stripped)
