Help with URL Parameters and HTML DataSet please.

Question

Hello everybody!
Looking at the example page: "Using URL Parameters to Control Data Regions", towards the bottom it gives an example of "Set by Product Name", from an XML DataSet using the following sample code:
    //Data set for the second example. var ds2 = new Spry.Data.XMLDataSet("../../demos/products/products.xml", "products/product");    //If the URL parameter 'product' has a value, set the XPath that includes a filter and then load the data. if (params.product){    ds2.setXPath("products/product[name = '"+params.product+"']");    ds2.loadData(); }
Can anyone please explain how to amend this to work with a HTML Dataset rather than XML?
The first example on the page (Set by RowID) works unchanged for the HTML DataSet, but I don't know what I should replace the 'setXPath' line with.
I see this has been asked before, but I'm afraid I can't find any answer that works (or, more often, that I can understand properly!)
Grateful for any suggestions.

Wow! Thanks Ben.
I hadn't thought about using Stacked Containers.
I'll test this out tonight and let you know how I get on.
Cheers,

A few days later and at last I've been able to test your suggestions.
I think I must be doing something wrong as the links and content don't work at all:
http://www.myosanthe-bernhard-huber.com/html/stack1.php
I know that the stacked containers do work (http://www.myosanthe-bernhard-huber.com/html/stack0.php), so I guess there are some errors in the coding somewhere.
Would you mind reviewing, please?
The important thing for me (in this case, anyway) is to get the called page's content using its 'Ref', and I'm not sure what benefit there is in using stacked containers as opposed to master-detail containers.
The master-detail method works reasonably well for me at
http://www.myosanthe-bernhard-huber.com/html/fotoalbum.php and sub-pages.
Perhaps I am betraying my lack of knowledge, but as I said in my original post, I think that I just need the HTMLDataSet equivalent to:
    //Data set for the second example.
var ds2 = new Spry.Data.XMLDataSet("../../demos/products/products.xml", "products/product");
   //If the URL parameter 'product' has a value, set the XPath that includes a filter and then load the data.
if (params.product){
   ds2.setXPath("products/product[name = '"+params.product+"']");
   ds2.loadData();
which as you can see uses an XMLDataSet, but does exactly what I need.

Thanks again for your help, Ben.
