Answer 1

Use ws.js

Here is how to fetch the file attachments:

const ws = require('ws.js')
const { Http, Mtom } = ws

var handlers =  [ new Mtom(), new Http()];
var request = '' +
                '' +
                  '' +
                      '' +
                  '' +
                '' +
              ''

var ctx = { request: request
          , contentType: "application/soap+xml"
          , url: "http://localhost:7171/Service/mtom"
          , action: "http://tempuri.org/IService/EchoFiles"
          }

ws.send(handlers, ctx, function(ctx) {
  //read an attachment from the soap response
  var file = ws.getAttachment(ctx, "response", "//*[local-name(.)='File1']")
  // work with the file
  fs.writeFileSync("result.jpg", file)
})

Two limitations:

• No basic auth provided out-of-box, patch required https://github.com/yaronn/ws.js/pull/40
• If the file name is an url, you need to apply another patch at mtom.js. Replace:

.

xpath = "//*[@href='cid:" + encodeURIComponent(id) + "']//parent::*"

with:

xpath = "//*[@href='cid:" + id + "']//parent::*"
