Ok, no one said I was an expert at regular expression. I am trying to write a regular expression to search for whole words (so anything bracketed by a non letter or number....so punctuation, space, etc...). The trick is also matching the start and end of line. So far, I haven't been able to figure out how to say "start of line OR punctuation character". Right now, I am just doing multiple searches (see below), and it works great, it just looks clumsy and amateurish (and all things considered, when it comes to regular expressions, I am an amateur).
Please tell me there is a more elegant way to write this search, by which I mean, write it in one expression.
expr = new RegExp('[^a-zA-Z0-9]'+searchString+'[^a-zA-Z0-9]',"gi"); exprST = new RegExp('^'+searchString+'[^a-zA-Z0-9]',"gi"); exprEND = new RegExp('[^a-zA-Z0-9]'+searchString+'$',"gi"); exprALL = new RegExp('^'+searchString+'$',"gi");
