Bruce CantorSubject: adding dtd reference to xml output via Xquery

I am trying to add the dtd reference on some xml out, but failing.

As far as I can see I should use the ddtek:serialize function to add the information , but I am having trouble getting it to work.
The docs says that cdata-section-elements are Modifiable but I cannot grab the concept of adding it, so that is actually comes out in the result.

This is the reference I would like to add: <!DOCTYPE cXML SYSTEM "http://xml.cXML.org/schemas/cXML/1.2.014/cXML.dtd">

I tried like this, and it does not fail, but it does not work either:


<cXML payloadID="{concat($timestampInMilisec,'@eet.group-',$environment )}" timestamp="{$timestamp}" xml:lang="{$SAPDoclang}">
Response information
, "indent=yes, omit-xml-declaration=yes, cdata-section-elements = DOCTYPE"

How do I add the reference in xquery, please?

Solution found (if anybody else has the same problem ):

Add doctype-system = http://xml.cXML.org/schemas/cXML/1.2.014/cXML.dtd as a serialization option.

Problem is that the above code returns escaped xml tags, like this:

<?xml version="1.0" encoding="UTF-8"?>&lt;!DOCTYPE cXML SYSTEM "http://xml.cXML.org/schemas/cXML/1.2.014/cXML.dtd"&gt;&#xD;
&lt;cXML payloadID="1675325426156@eet.group-Local" xml:lang="en-US" timestamp="2023-02-02T09:10:26.156+01:00"&gt;&#xD;
&lt;Status xml:lang="en-US" code="200" text="OK"/&gt;&#xD;

Does anyone know how to make the result include 'normal' XML tags?

If I use the ddtek:parse function around the serialize it will return 'normal' looking XML, but then the dtd reference goes missing:

<?xml version="1.0" encoding="UTF-8"?>
<cXML payloadID="1675325557316@eet.group-Local" xml:lang="en-US" timestamp="2023-02-02T09:12:37.316+01:00" version="1.2.014">
<Status xml:lang="en-US" code="200" text="OK"/>

ddtek:serialize produces text not XML.

Please post a complete xquery example of your code.

The following query shows two methods to output a DTD declaration

1) in the main query output
2) in a secondary output using ddtek:serialize-to-url

declare option ddtek:serialize "indent=yes, doctype-system='http://xml.cXML.org/schemas/cXML/1.2.014/cXML.dtd'";
let $xml := <root/>
return (
"indent=yes, doctype-system='http://xml.cXML.org/schemas/cXML/1.2.014/cXML.dtd'")
