Can we access a json element inside flow variables in Mule?
Eg: My flowVar value is {

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

Answer 1

try the below expression,
#[json:/Input1/Value1]

Answer 2

You can use dw function or json path expression to achieve this.
examples:
[dw('payload.Request.name')]
[json:Request/name]

Answer 3

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

Let says if you have stored this json in flow variable (xyz) then you can access it using the bellow syntax:
