Using XSLT with the DOM or SAX

Microsoft® XML Core Services (MSXML) makes XSLT services available from the Document Object Model (DOM). This integration of XSLT with the DOM makes XML applications simpler and more powerful. XSLT becomes a general service for locating and manipulating XML data in Web pages, server-side applications, and stand-alone applications.
