Find in HTML page, move mouse and click it

[sonic]

Hello,

I have a string, what i want is to search for it in an Webpage, if it's found i want the URL be clicked/copied.

Any ideas on how to manage this?

Example:

Str test="find this"
Webpage to search in: http://www.test.com/testpage.htm
Search for the string test in this page and copy the URL/click it with a left button

TIA
