Retrieve File Attachment using Jscript

Summary

GetFileData call using Jscript

Content

Hello everyone -

I am trying to retrieve the file data from Jscript. I am using XMLHttpRequest to post the request XML of GetFileData and get back the binary data of the file attachment. I have provided the code snippet below.

I can get the binary data response from the XMLHttpRequest though my call to SOAP end point and submission of xml in the send method goes through fine. I am wondering what I am doing wrong?  Essentially, objXMLHttpRequest.responseText does not bring me the file data that I would expect in this call.

Thanks,
