Find In Page searching another html page?

Hi there,

It is possible to perform a find in page search that looks at a specific link, opens the page in a new window and finds the text within that document??

Basically I regularly use an html page in work that has a list of people and their telephone numbers.

I want to be able to type in a searchbox on my main page and it open the target page and find the name I am looking for?

Is this possible or can you only Find In Page on the same page or another frame?

Tearing my hair out........

Thanks
