Group by parameter value

Question

Hi,
How can I group by a parameter value?
For instance, I have the following:
<?for-each-group:Opportunity[there is a filter here];./ResponsibleDepartment?>
This grouping works fine if I enter field values such as "ResponsibleDepartment" (as in the above exmaple), "Product", and "User". Each of these values refer to actual field names. I would like instead to use a parameter, but unable to use a parameter as in the following:
<?for-each-group:Opportunity[there is a filter here];./$ParamGroupBy?>
(the parameters that the user can choose are the actual field names).
This results in error. Can I not use a parameter in this way in a group?

Hey Sorry. Didnt test it.
If its going to be a xdoxslt variable then you can do it as
<?xdoxslt:set_variable($_XDOCTX,'grp', 'DEPT')?>
<?for-each-group:/ROOT/EMPLOYEE; ./*[name()=xdoxslt:get_variable($_XDOCTX,'grp')]?>
<?NAME?>
<?SALARY?>
<?end for-each-group?>
For the sample xml
<ROOT>
<EMPLOYEE>
<NAME>Name1</NAME>
<DEPT>Sales</DEPT>
<SALARY>1000</SALARY>
</EMPLOYEE>
<EMPLOYEE>
<NAME>Name2</NAME>
<DEPT>Development</DEPT>
<SALARY>1200</SALARY>
</EMPLOYEE>
</ROOT>
I am not sure how it can be done for xsl variables.
You can refer http://blogs.oracle.com/xmlpublisher/2006/05/dynamic_sorting_or_sort_by_par_1.html for more details on its usage.
The blog has usage details of xsl variables too in this context.
