Is that a question?
                  ^

You can use String.prototype.replace() passing a reference to a RegExp 
instance with alternation and global flag set while giving precedence to the 
alternatives that match substrings that you wish to ignore, and a reference 
to a Function instance for replacer function.  Then return from that 
function the match for them, and the highlighted match for the rest.

That said, at your current position in the learning curve you should not 
attempt to parse provably non-regular languages like HTML using regular 
expressions.

Yes.  Please do not shout.  And do not use the borked, spammed, and
troll-infested Google Groups for posting; use a decent newsreader.
