Re^2: HTML stripper...

It's invalid because there's no space before -->

That's bogus. There's no need for space to be there. Nor does there have to be space as the first character following a COM sequence (COM being --).

OTOH, your pattern falsely considers  to be a valid comment, while it doesn't consider  --> to be valid.

This matches HTML comments:

  <!(?:--(?:[^-]*(?:-[^-]+)*)--\s*)*>

although if you are truely pedantic, you'd replace the \s with the set of characters the HTML DTD defines as white space characters.

Firstly, I've added an update to my post, please read that. Secondly, rather than just stating "That's bogus ...", perhaps you could cite a reference. -- Ken	[reply]
