Unable to capture value form request using Xpath

[amit me]

Hi I am trying to capture the value from Request using Xpath but it is not working. I have captured the simulation json which has XML body for a post request but when I tried to capture value from XML body it not working. Kindly help.

Request- response pair has below items:

Request from postman:

URI: www.test.com

Method: Post

Body: xml= <root><id>8</id></root>

In simulate.json:

"body": [

{

"matcher": "glob",

"value": "*"

}

Using below xpath in response in simulate.json:

"response": {

"status": 200,

"body": "<id>{{   Request.Body \"xpath\"  \"/root/id\" }}</id>",

 But after running it gives result as <id></id>. Please help here.
