XML transformation based on parameters

Hi All,

I'm using latest version of Stylus Studio, to develop a XSLT (based on
Saxon 9.0.1.5 processor) to do the following simple (should be)
transformation.

>From XML:

<GetCatalog>
   <ListOfCatalog>
        <Catalog>
           <Id> <param name="same/new">foo</param> </Id>
        </Catalog>
   </ListOfCatalog>
</GetCatalog>

The destination must depends on "name" attribute of param element. If
name="same" the following XML must be returned:

<GetCatalog>
   <ListOfCatalog>
        <Catalog>
           <Id> foo </Id>
        </Catalog>
   </ListOfCatalog>
</GetCatalog>

Otherwise:

<GetCatalog>
   <ListOfCatalog>
        <Catalog>
           <Id> newvalue </Id>
        </Catalog>
   </ListOfCatalog>
</GetCatalog>

In both cases <param> element has to be removed.

Now, I have two issues. First of all the management of this
"parameters".Secondly, every xml elements (GetCatalog, ListOfCatalog,
etc etc) could change: only tag "param" will be the same.

Thanks a lot in advance,
emiliano
