Highlighting a word in a HTML string.

Question

Hi all,

I am trying to find a way to highlight a word in a string e.g.

1. Test <a href="string">string</a>

2. Test string

In 1. the "string" in the "href" must not be highlighted except maybe the "string" in the innerText, but in 2. "string" has to be highlighted.

Is there a regular expression or something I can use?

Thanks in advance,

Lee
