Question

I face the common cross domain issue with xmlhttp.

I am trying to access WSDL web service using the SOAP protocol. I am not using php and so I can not use the

header('Access-Control-Allow-Origin: *');

I also can’t use JSONP as the response I get is not in JSON format but in XML format.
Is there any other way that I can resolve this issue.

Here is my code snippet.

var user1="user_name";
var pass1="******";
var url="http://ideone.com/api/1/service.wsdl";

var soap_msg="<?xml version='1.0' encoding='UTF-8' standalone='no'?>"+
"<SOAP-ENV:Envelope xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/'"+          
"xmlns:tns='http://ideone.com:80/api/1/service'    xmlns:soap='http://schemas.xmlsoap.org/wsdl/soap/'"+
"xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:wsdl='http://schemas.xmlsoap.org/wsdl/'"+
"xmlns:soap-enc='http://schemas.xmlsoap.org/soap/encoding/' "+
"xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' >"+
"<SOAP-ENV:Body><mns:getLanguages xmlns:mns='http://ideone.com:80/api/1/service' SOAP-  ENV:encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'>"+
"<user xsi:type='xsd:string'>"+user1 +"</user><pass xsi:type='xsd:string'>"+pass1+"</pass>"+    
"</mns:getLanguages></SOAP-ENV:Body></SOAP-ENV:Envelope>";
var oXmlHttp=  new XMLHttpRequest();
oXmlHttp.open("POST",url,true);
oXmlHttp.setRequestHeader("Content-Type", "text/xml");
oXmlHttp.setRequestHeader("SOAPAction", "http://ideone.com/api/1/service#getLanguages");
oXmlHttp.setRequestHeader("Access-Control-Allow-Origin", "*");
oXmlHttp.send(soap_msg);
var res=oXmlHttp.responseXML;

Thanks in advance.

Here’s a link from YUI that you will probably find useful.

http://developer.yahoo.com/yql/guide/yql-jsonp-x.html

They’ve written a callback which is essentially an envelope that allows for XML to be returned.
