But those are all enclosed in HTML tags, even with something as sucky as MS

There's your true problem.

An HTML tag can span multiple lines, regardless of where it comes from.

Even my hand-coded HTML will occasionally end up with a multi-line HTML
tag... Well, okay, maybe not, but I could if I wanted to :-)

You need to http://php.net/implode all your HTML into one big long string
*before* you strip_tags:

$html = implode('', $html);
$html = strip_tags($html);

If you really need the multi-line HTML turned into an array after that, you
can do:

$html = explode("\n", $html);

But you probably are storing this stuff in a file or database, and it's just
as easy to fwrite the large string as to mess with it as an array.
