Rob,
My problem is that I have no way of knowing where the keyword may
appear. It might be tabular data (<TD>) or in descriptive paragraph
(<p>).
So if my keyword is RED, then...
BEFORE
<p> the red fox </p>
AFTER
<p>the <span>red</span> fox</p>
I'll have an array of keywords as well. var arrayx["one", "two"
"three"]
