Access Json element in Flow Variable - Mule 3.7

Question

Can we access a json element inside flow variables in Mule?

Eg: My flowVar value is { "Input1": { "Value1": "UNITED STATES" } }

How can I access the element 'Value1' using MEL in mule?

Thanks, ROA

Right answer is

#[flowVars.theVariable.Input1.Value1]

but get here you need a lot what to do. You have to create variable appropriately to match your description. Also name of the variable is missed but you need it anyway. Here is code

    <flow name="AccessFlowVariable">
        <poll doc:name="Poll">
            <fixed-frequency-scheduler frequency="10000000"/>
            <logger message="Flow started" level="INFO" doc:name="Logger"/>
        </poll>
        <dw:transform-message doc:name="Transform Message">
            <dw:set-variable variableName="theVariable"><![CDATA[%dw 1.0
%output application/java
---
{ "Input1": { "Value1": "UNITED STATES" } }]]></dw:set-variable>
        </dw:transform-message>
        <logger message="#[flowVars.theVariable.Input1.Value1]" level="INFO" doc:name="Logger"/>
        <logger level="INFO" doc:name="Logger"/>
    </flow>

and here is result
