Was wondering if anyone has any thoughts on the best way to accomplish something a little different and slightly unusual.

I have a master page which lists two columns of text in hyperlink format.  They are listed as Practice Areas and Industry Groups.  

The first data list url uses a parameter named PA=x

The second data list uses a parameter named IG=x. 

Both urls point to the same child page, just different url parameter name and values are used.

Unfortunately, I dont have much control over the custom module which displays the data in this manner.

I'd like to use <xmod:select> to evaluate and inject a dynamic meta tag page title (depending upon the name and value of the url parameter passed).

Is it possible to have a <xmod:select> tag evaluate the url parameter name, (not value) in some manner and then define a different list source depending upon the evaluation results?

For example, if the url parameter name is IG, use one list data source to lookup the IG name. 

If the parameter name is PA, use a different list datasource to lookup the Practice Area name. 

Any thoughts are appreciated.

Thanks..
Mark
