hiliting all instances of a string in a field

[Trevor DeVore]

Has anyone written a function that will find all instances of a string 
in the htmlText of a field EXCEPT if it appears in a tag such as 
<a></a>?  I need to hilite all instances of the string in the field.  I 
figure I'm either missing a really obvious function already in Rev that 
will do it or I need a fancy regular expression.
