can anybody tell me how to output an xml file using xquery, which contains processing instructions?
for instance to include the prolog of the xml document like:
<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?>
<!DOCTYPE mymodel SYSTEM "http://www.test.com/model.dtd">

Thanks!
David

XQuery the language won't allow you to create specific <?xml PIs or DOCTYPE declarations; but the serializer may.

The Stylus Studio built-in processor doesn't support those serialization properties; Saxon should:

declare namespace saxon="http://saxon.sf.net/";
declare option saxon:output "encoding=ISO-8859-1";
declare option saxon:output "standalone='no'";
declare option saxon:output "doctype-system=http://www.test.com/model.dtd";

You won't see PI or DOCTYPE when run in XQuery editor, but if you generate Java code (XQuery > Generate Java Code) and run it, you will see the DOCTYPE is generated; you probably need to serialize the result in a way different from what the generated Java code is doing to also see the XML PI.

Hope this helps,
