Detailed Description

Supports the sorting of a node set by an XPath expression of the following types: numeric, string, time, P6FLOAT, and P6INT64.

This is used in support of the XSLT sorting feature. To get this interface the caller must do a queryInterface on the p6IDOMNodeset of an existing node set component. As a code example:

 p6IDOMNodeset*     pSet;
 p6IDOMNodesetSort* pSort;
 
 if (P6SUCCEEDED( err = pSet->queryInterface( VALIDATEIF( p6IDOMNodesetSort, &pSort ))))
 {
      err = pSort->reverseOrder();
     pSort->release();
 }
