Parse push notification messages

[e10jon]

I am able to subscribe to push notifications and receive events via a callback url. The problem is, when those XML events come in, how do I parse them into library objects?

Example XML is below. I would like to be able to do something like const message = new EWS.Message(rawXml) but I can't figure it out.

<?xml version="1.0" encoding="UTF-8"?>
<soap11:Envelope xmlns:soap11="http://schemas.xmlsoap.org/soap/envelope/">
  <soap11:Header>
    <t:RequestServerVersion xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" Version="Exchange2013_SP1" />
  </soap11:Header>
  <soap11:Body>
    <m:SendNotification xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">
      <m:ResponseMessages>
        <m:SendNotificationResponseMessage ResponseClass="Success">
          <m:ResponseCode>NoError</m:ResponseCode>
          <m:Notification>
            <t:SubscriptionId>EgBoaXRleDIuZmxob3VzZS5pbnQQAAAAp6l9rcjsFU6mlII+hEsD+vKtJTm15NkIEAAAALo1KNrW4vpPpUP1v28hRgY=</t:SubscriptionId>

            </t:ModifiedEvent>

              <t:FolderId Id="AQMkAGRhMjgzNWJhLWUyZDYtNGZmAGEtYTU0My1mNWJmNmYyMTQ2MDYALgAAA3xncVSjc8ZHvGV7TiOhh38BAH9j2HIkphtJl9b7SUJ48kcAAAIBDQAAAA==" ChangeKey="AgAAAA==" />
              <t:ParentFolderId Id="AQMkAGRhMjgzNWJhLWUyZDYtNGZmAGEtYTU0My1mNWJmNmYyMTQ2MDYALgAAA3xncVSjc8ZHvGV7TiOhh38BAH9j2HIkphtJl9b7SUJ48kcAAAIBCAAAAA==" ChangeKey="AQAAAA==" />
            </t:ModifiedEvent>
          </m:Notification>
        </m:SendNotificationResponseMessage>
      </m:ResponseMessages>
    </m:SendNotification>
  </soap11:Body>
</soap11:Envelope>

Separately, I had to hard-code the following XML string response to send to EWS such that the push subscription would remain open. Is there a way to do this via the library?

<?xml version="1.0"?>
<s:Envelope xmlns:s= "http://schemas.xmlsoap.org/soap/envelope/">
  <s:Body>
    <SendNotificationResult xmlns="http://schemas.microsoft.com/exchange/services/2006/messages">
      <SubscriptionStatus>OK</SubscriptionStatus>
    </SendNotificationResult>
  </s:Body>
</s:Envelope>

I was able to figure out the parsing like this:

const domParser = new EWS.DOMParser()
const xmlDoc = domParser.parseFromString(xmlString)
const xml2Js = new EWS.xml2JsObject()
const jsObj = xml2Js.parseXMLNode(xmlDoc.documentElement, true)

console.log(jsObj)

there is no built in method to parse this. you are on right track here
