Create Bulk XML from template for POST request.

Hello,

I want to send bulk xml to my soap request body. I want to know is there any way to generate them dynamically through Gatling/Scala
This is how I am doing

private val request=exec(
  http("Post request to create")
    .post("/endPoint")
    .headers(Utils.soapHeaders)
    .body(ElFileBody("requestbody/ids.xml"))
    .check(status.is(Utils.successStatus))
)
private val feedId = Iterator.continually(
  Map(
      "id" -> Random.alphanumeric.take(13).mkString,
      "transactionId" -> Random.alphanumeric.take(14).mkString
    )
  )

val scnPostVehicleAsn=Utils.createScenario("soapService", feedId, request)


and requestbody/ids.xml has the template with dynamic values ${transactionId} & ${id}.

So Is there any way to dynamically generate xml based on template, I am not looking for repeat functioanlity .
 Just generate xml once before execution and pass it and later I will make rest calls to validate them

Ok I figured it out myself. I have created a list of random number and passed it to xml directly

val randomNumbers = List.fill(number)(prefix.concat(Random.alphanumeric.take(13).mkString))

{ randomNumbers.map( i => i}

Then,

val file = new File(System.getProperty("user.dir") +"/performance-tests/src/test/resources/requestBody/ids.xml")
val bw = new BufferedWriter(new FileWriter(file))
bw.write(VehicleAsns.toString())
bw.close()
