How do i save a XML file that is been sent to my web API

Question

i have a post web API which receives an XML file and with this files it triggers a process model. but unfortunately when we get the file we just get the XML file content. it's like we where getting just the content of the XML and this is a signed file that should not be modified that's why i hesitate on just cutting the text and paste it in a new file.

my web API 
 
 This is what we are getting in the body of the httprequest 
 
 is there a way on turning this into the sent xml file again ? 
 
 just for letting you know the a!httpresponse.formData is empty because we are not using the xx-www-form-urleenconded

If you are looking for document as an attachment to the web API request, use following. 
 - While creating a WebAPI use the "Document Upload" template as shown below. While creating the WebAPI object it will ask for a folder to save the document.

a!localVariables(

 /*Check whether the request body contains a document*/
 local!success: not(isnull(http!request.body)),

 if(
 local!success,

 /*If a document was uploaded, return a successful response*/
 a!httpResponse(
 statusCode: 200,
 headers: {},

 /*Print the document id, name, and extension of the uploaded document*/
 body: concat(
 "Upload Successful: ",
 document(http!request.body, "id"),
 " - ",
 document(http!request.body, "name"),
 ".",
 document(http!request.body, "extension")
 )
 ),

 /*If no document was uploaded, return an error code*/
 a!httpResponse(
 statusCode: 400,
 headers: {},
 body: "400 Document Not Provided"
 )
 )
)
