Is this functionality possible?
<p>Does anyone know if the following is possible please? (and the best way to do it)</p>

<ul>
<li><p>code that searches through a pages content</p></li>
<li><p>finds any names that are defined in a seperate text file</p></li>
<li><p>if it finds any matches it adds a hyperlink to the name</p></li>
<li><p>the hyperlink opens a tooltip on hover, pulling in relevant data from the seperate text file</p></li>
</ul>

<p>Any ideas/help greatly appreciated. </p>
