Where are you seeing "DTL response = <ID scope='Message'>3</ID>"?

What you see is the "representation", the "export" of your XML enabled class rendered by...whatever you are using to view/display it, the quotes are not part of the content.

How are you using/consuming your target (DTL response)? Some XML (SOAP? REST?) message? If so, I believe that you won't find single quotes when you will use it.

This is just guessing, because you don't provide any context/detail.

Hi John,

for JSON the correct property parameter is %JSONFIELDNAME, documented here.

Adding %JSONFIELDNAME = "TheName" to the Name property in my sample above, the JSON result is:

{"Slide":[{"TheName":"Name1"},{"TheName":"Name2"},{"TheName":"Name3"}]}

Following your enthusiasm I implemented a little test 😁

Class Community.Array.Base Extends (%RegisteredObject, %XML.Adaptor, %JSON.Adaptor)
{

Property Slide As list Of Community.Array.Slide(XMLPROJECTION = "ELEMENT");

ClassMethod test()
{
	Set Base=##class(Community.Array.Base).%New()
	For i=1:1:3 {
		Set Slide=##class(Community.Array.Slide).%New()
		Set Slide.Name="Name"_i
		Do Base.Slide.Insert(Slide)
	}
	Do Base.XMLExport(,",indent")
	Write !,"JSON: ",!
	Do Base.%JSONExport()
}

}

Class Community.Array.Slide Extends (%RegisteredObject, %XML.Adaptor, %JSON.Adaptor)
{

Property Name As %String;

}

The output is:

USER>Do ##class(Community.Array.Base).test()
<Base>
  <Slide>
    <Name>Name1</Name>
  </Slide>
  <Slide>
    <Name>Name2</Name>
  </Slide>
  <Slide>
    <Name>Name3</Name>
  </Slide>
</Base>
 
JSON:
{"Slide":[{"Name":"Name1"},{"Name":"Name2"},{"Name":"Name3"}]}

Is this what you need?

We are not InterSystems support team, we are a Developer Community. 😊

You can download it from WRC (Worldwide Response Center) portal, the official InterSystems Support.

If your system is under support/maintenance you should have access to it.

If you your system is not covered by support/maintenance, you are not entitled to updates.

For testing purpose you may use/download IRIS Community Edition.

I've never done it but it should work, the correct syntax is MSH:4, not MSH-4. 

Instead of using array use list, possibly with XMLPROJECTION = "ELEMENT", something like:

Property Slide As list Of Q.Interface.Fragment.IMS.Slide(XMLPROJECTION = "ELEMENT");

This way you get what you need.

What platform? Windows? Linux, what distro?

Many ways to do it, my way:

USER>Set input=25
 
USER>Set ln=10
 
USER>Set $Piece(Pad,"0",ln-$Length(input))="0"
 
USER>Set Padded=Pad_input
 
USER>Write
 
Pad="00000000"
Padded="0000000025"
input=25
ln=10

I'm trying to convert date - 2023-09-28T20:35:41Z to BST/GMT format.

Please note that BST and GMT are not "format" and (may) have different values.
From your answer to @Robert Cemper it seems you need to covert to BST value (not GMT) and to "yyyymmddhhmmss" format.

To answer your question, is BST your system local timezone?

If you don't like the default behavior, change it. 😊

You can change it system wide from Management Portal, System Administration -> Security -> System Security -> System-wide Security Parameters
There you can change "Inactive limit" to 0 (zero), this way accounts never expire.

You can also change it for any individual user accounts in Management Portal, System Administration -> Security -> Users -> (select the user)
There you can enable the checkbox "Account Never Expires".

Instead of the $SYSTEM "shortcut", use the actual full syntax:

JOB ##class(%SYSTEM.OBJ).Export("RICHS.int","c:\AAA\richh.rtn")

HS.FHIR.DTL.vR4.Model.Resource.Encounter is a %RegisteredObject, it cannot be used as interoperability request/response.

An interoperability response/request MUST be a persistent class.

To loop/list all files within a directory, possibly with wildcard filter, you can use the FileSet class query in %Library.File class, see documentation on Query Directories and Drives, List the Contents of a Directory.

You have a superclass with some logging method. Now every time the logging method is called from a child class it logs the name of the superclass instead of the Child class?

No

If so the issue is that $CLASSNAME returns the name of the class where the method is located not where a method is called from.

Wrong, it returns the class name where it is called from.

Your first sample method works just fine, no need for method generator.

I suggest you to make a quick test.

I don't understand what you refer with "the name of the item which created it", can you provide an example of what you expect as result?

$CLASSNAME($THIS) returns the actual class name of $this instance, not a superclass or the class where is executed (possibly a superclass).
