Diferentiating the last element..

["Eduardo Dominguez" <edmz@xxxxxxxxxxxxxx>]

I have a small dtd for definig libraries of functions. This
is an excerpt from a test file:

  <function name="setUserId" description="blah here">
   <parameter name="$id" description="desc here" datatype="string" />
   <parameter name="$value" description="blah blah" datatype="int" />
  </function>

What I need to do, is to create skeleton files from the description
of the library. For example (in php):

/** 
 *blah here
 *
 *@para $id desc here
 *@para $value blah blah
 */
 setUserId( $id, $value )
 {

 }


My problem is i want to print the parameters, and as you might know
the last parameter must not be followed by a comma (",") thus my 
need to identificate when I am at the last "parameter" element.

Is this possible, and if so, how ?

thanks in advance.
