A fellow emailed me wanting to get a PDF file out of a SOAP Envelope and write it directly out to the browser using Classic ASP.  Here's the code I used:

<%
Set m_Doc = Server.CreateObject("MSXML2.DOMDocument")
m_Doc.async = false
m_Doc.ValidateOnParse = false
'This could come from whereever, ADO, a file, another Web Service.
m_Doc.Load Server.MapPath(".") + "\\soapresponse.txt" 
    
'Yes, it's a // XPath, but that's the LEAST of our problems before we get into microperf
Set oNode = m_Doc.selectSingleNode("//GetImageAsBase64Result")
'This is the Magic that makes it possible.  Otherwise you'll get a string.
oNode.dataType = "bin.base64"
Response.ContentType="application/pdf"
Response.AddHeader "Content-Disposition", "filename=whatever.pdf"
Response.BinaryWrite oNode.nodeTypedValue
%>

This is given a SOAP Response like this:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GetImageAsBase64Response xmlns="http://localhost/">
<GetImageAsBase64Result>JVBERi0xLjI SNIP....etc...
