[MarkLogic Dev General] Adding XML declaration

[Ron Hitchens]

   You can't, really.  The XML declaration is a
processing instruction that indicates how to interpret
the textual representation of XML that follows.  In XQuery,
you're already "inside" and you're creating XML data
structures directly - as opposed to generating a text
file that represents a serialization of XML.

   If, for some reason, it's necessary to place the
XML declaration at the beginning of a serialized XML
that you're producing, you can prepend it to a textual
representation of your XML, but that is technically
different than "adding" it to the XML.

   Try something like this (note that this is actually
producing a sequence of two items rather than a text
file):

xquery version "1.0-ml";

let $prolog := '<?xml version="1.0" encoding="UTF-8"?>'
let $newXML:=
element result
 {
  element header
  {
    element topic1 { "xyz"},
    element topic2 { "abc" },
    element topic3 {
      element subTopic { attribute checked {"true"}, text {""} }
    }
  }
}

return ($prolog, $newXML)
