Hi,

I am currently involved in a project to upgrade a 2.0.1 MQSI implementation to WMQI 2.1.

In 2.0.1 if you have the following MRM-defined XML for example:

<Person>
<Name>Kuli</Name>
<Age>29</Age>
</Person>

Then the Name can be referenced as:

Body.Person.Name

In 2.1, if I import the same message set using the -x XML param to include the XML physical layer to the MRM-domain message (or indeed if I create it manually, or via DTD-importing), the trace shows me that name is now referenced as:

Body.Name

How do I get the root node of the XML in the data tree?

I refer you to page 72 of the 'Working with Messages manual' as follows, which seems to confirm my findings:

----------------------------------------------------------------------------------------------------------------

Referencing simple types

A simple type does not have an identifier that uniquely defines it in ESQL,
therefore if you want to interrogate or update a simple type, you must reference it
in relation to other known objects in the message.
If you are working with the following XML message:

<Mess1><Elem1>abc</Elem1><Elem2>abc<Child1>def</Child1></Elem2></Mess1>

you can model this using the following objects:

Message

The message Identifier property is set to Mess1 , the Type property is set to
tMess1 .

Type

The compound type Identifier property is set to tMess1 , the Type Composition
property is set to Sequence . The compound type contains the following
objects:

Simple Type

STRING

Element

The element Identifier property is set to Elem1 , the Type property is
set to simple type STRING .

Element

The element Identifier property is set to Elem2 , the Type property is
set to compound type tElem2 .

Type

The compound type Identifier property is set to tElem2 , the Type Composition
property is set to Ordered Set , the Type property (the compound type’s
base type) is set to null . This compound type contains the following object:

Element

The element Identifier property is set to Child1 , the Type property is
set to simple type STRING .

If you want to set the value of Elem1 to xyz , use the following ESQL:

SET OutputRoot.MRM.Elem1.*[1 ]=’xyz ’;

Any help would me much appreciated!
