How do I take my SOAP UI call and use it in HTML?

Ok here's what the raw tab says:
POST "https://mywebsvr HTTP/1.1"
Accept-Encoding: gzip, deflate
Content-Type: text/xml; charset=UTF-8
SOAP Action:""
User-Agent: Jakarta Commons-HttpClient/3.1
Content-Length: 209
Authorization:Basic "encodedstring"
Host: "mywebsvr"

Here is what I would like to do:
send an xmlhttprequest to the server. So would I add all of these fields as headers to my xmlhttprequest ?
