Link a visible node in a table to another

[cube27]

I am working on a website that creates a table utilizing xsl and xml. The table is about courses that are being taught, with info such as when, where, time, etc. That was done fine, now they want a description of the course. Problem is there is no room left in the web page. The boss man came up with a smart idea of having the description node linked to the class name node (which is visible in the table) in such a way as mousing over the class name would pop up a bubble with the course description. I’ve searched and searched, and cannot find anything to help me. Is this even possible? Thanks for any advice.

Is the final result page (X)HTML? If so, you could use the title attribute.

I'm not sure off the top of my head how to generate tooltips in generic XML.

Yes, the final result is an (X)Html page. The description of the course (as well as all the nodes) is in Excel form that is converted into XML by a VBA script. This is so the secretary can do it up, push one button, and get me an updated XML, to spread the work load and to keep the table on the web page current. If this will let me link to an unseen node (description), this is the ticket. Will try. Thanks again
