Title	Test Details Cleaning HTML
Expression	<\/{0,1}(?!\/|b>|i>|p>|a\s|a>|br|em>|ol|li|strong>)[^>]*>
Description	following a bit of work this morning trying to get something to strip out arbitrary html but leave 'known' tags in place, we have come up with the following which may be useful. This uses the 'negative lookahead' construct using '?!' It looks for an angle bracket and perhaps a backslash, as long as it is *not* followed by one of the terms in the ?! section. The brackets in this section do not return a value, they are part of the construct. This regexp can therefore be used to replace all unknown tags with blanks. Obviously you can add other 'good' html tags to the list.
Matches	<table>...</table>
Non-Matches	blah blah blah.
