message definition
within the tag Quantity , a wildcard attribute and a wildcard element are defined.
That part of the message definition file is like this .
Quantity xs:anyType
- Wildcard Attribute
- WIldcard Element
Input
In the input , Value present in Quantity tag is 1. <Quantity>1</Quantity>
testing
Now, i am trying to get the value of Quantity using the following esql code.
| Code: |
| SET Environment.refer = FIELDVALUE(InputRoot.MRM.*:Data.*:Request.*:Operator.*:Quantity); |
But, nothing is being returned. Environment tree is not constructed.
I also tried this 2nd code.
| Code: |
| SET Environment.refer = InputRoot.MRM.*:Data.*:Request.*:Operator.*:Quantity; |
Now, the Environment tree is constructed with the pre-defined child refer.But, again nothing is present in it.
How should we access the part of the MRM message that is having wildcards defined within it ? |

There's an easy way to answer this question, and all similar ones. Look at the message tree ( using the debugger or a Trace node ). It will clearly show you the path from the root to any element in the tree. That is the path you need to use in your ESQL.
Hint : You do not need to use .* if you know the name of the element which you are trying to access. |

Kimbert, Thanks for the reply.

I am debugging the code and checking the message tree sturcture.
I re-checked the path from the ROOT to the QUANTITY element,
and giving the same path within the code.

Here, the elements are namespace-defined.
For time being,i have replaced the namespaces with * in the code.
Even while trying the below code also, The Quantity tag is found empty.
| Code: |
| SET Environment.refer = InputRoot.MRM.*:Data.*:Request.*:Operator; |
The only difference with Quantity tag when compared to other elements is
"it has a wildcard element and a wildcard attribute defined within it".
How can we access these sought of elements ? |

| The fact that the model contains a wildcard should not make any difference at all. Please post the Trace node output - at least then we can check that your path looks OK. |
