accessing serialized contents of a file

Question

I am accessing the xml file from the S3 bucket using

var params = {
  Bucket: "bucketName", 
  Key: "xmlFileName.xml"
 };

 s3.getObject(params, function(err, data) 
 {
   if (!err) 
   {
       console.log(data);
   }
}

If I open up the comment in the log I get

 2017-12-21T04:23:53.991Z   bf6be172-e606-11e7-97cb-2139c6f9555f    { AcceptRanges: 'bytes',

Im assuming the content of the body is the serialized contents of the Xml file...Now how do I store this in a variable?

Ive tried

data.body
data[0].body

both coming back as undefined.

Please advise

try finding out what data is. YOu can type "typeof data" in the javascript console — Anthony McGrath, Dec 21 '17 at 04:59

Try data.Body (capital letter). It's a Buffer so you'll need to convert it to a String before parsing the XML - try:

var xmlString = data.Body.toString()
