Sorry, Gururaj, but that answer seems wrong to me for two reasons.
1. Firstly, ProcessingInstructions are inherited from Nodes, so your answer
appears like a recasting of this:

And probably would have the same result.
Secondly, appending a child adds the PI at the end of the document, which is
not what Sambasivarao wants. Instead,
you do something like this:
String data = "type=\"text/xsl\" href=\"cdcatalog.xsl\"";
ProcessingInstruction pi =
doc.createProcessingInstruction("xml-stylesheet",data);
doc.insertBefore((Node)pi,doc.getFirstChild());
That's my guess, based on testing something similar with Xerces C++ as the
base. The result: the PI was inserted before the element. I can't really see
any difference with a Java implementation.
