So I am just starting to learn how to code so please excuse the total stupidity of my question.

I'm trying to work with the API of a service and set up an XML search. They are telling me that I need to use an assigned URL (which I have) to request XML results. The XML document will will validate against their DTD (which I also have). They have also provided the following info (which makes little sense to me):

In order to accurately track job clicks, publishers are required to insert the "onMouseDown" attribute to all job link anchor tags and add the corresponding JavaScript source to all pages that display data from the API.:
< href="..." onMouseDown="xml_sclk(this);">View Job</a>

and

<script type="text/javascript" src="http://api.simplyhired.com/c/jobs-api/js/xml-v2.js"></script>

How do I set this up?
