I usually do something like this (untested):
str = REreplaceNoCase(str, "<(/?)(b|i|strong|p)", "#chr(5)#\1\2", "all");
str = REreplaceNoCase(str,"</?[^>]*>","","all");
str = replace(str, chr(5), "<", "all");
Wrap it up in a UDF that takes the list of allowed tags as a
parameter, and you can use it all over the place.
