[Javascript] problem with ResponseXml.

[KaNos]

Hello aspx world,
I consume a webservice with Javascript functions.
But the response is ok and, very strange, document is null.
How to resolve this problem thanks ??????



xmlHttpRequest.open("POST", myAddressLocation, false);
xmlHttpRequest.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
xmlHttpRequest.send(xmldocumentSoapRequest);
if (xmlHttpRequest.readyState == 4)
{
alert(xmlHttpRequest.responseText); // response ok

var xmldocumentSoapResponse = xmlHttpRequest.responseXML;

alert(xmldocumentSoapResponse.documentElement == null); // response is
true ?
}

The well formed webservice response with responseText.

<?xml version="1.0" encoding="utf-8"?>

Check xmlHttpRequest.getAllResponseHeaders(), what does that show, in
particular for the HTTP Content-Type header?
And if that is script with IE then check
xmlHttpRequest.responseXML.parseError.errorCode
If that is not 0 then check
xmlHttpRequest.responseXML.parseError.reason

Hello Martin,
The HTTP Header is :

Server: Microsoft-IIS/5.1
Date: Tue, 08 Aug 2006 15:54:04 GMT
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Cache-Control: private, max-age=0
Content-Type: application/soap+xml; charset=utf-8
Content-Length: 1289

And xmlHttpRequest.responseXML.parseError.errorCode is 0. So i think no
error.
Where is my problem ?
Thanks,

I think the problem is
Content-Type: application/soap+xml
which is probably technically correct but not recognized by
MSXML/XMLHttpRequest as an XML MIME type, it only looks for
application/xml or text/xml to decide whether to populate responseXML.

So you either need to change the server to send the generic XML
Content-Type application/xml or you need to try to solve that on the
client where with MSXML/IE you could do e.g.
xmlHttpRequest.responseXML.load(xmlHttpRequest.responseBody)
when you receive the response.

With Mozilla you can do
xmlHttpRequest.overrideMimeType('application/xml')
before you send the request to convince it to parse the response as XML
into the responseXML object even if the Content-Type the server sends is
not recognized as an XML MIME type.

Great Martin,
I've developed the webservice in C# with DotNet V2. Do uou know how can
i do to change the XML MIME type directly in the webservice source code ?
Real Thanks,

If your class implementing the web service inherits from the WebService
class then in the web service methods I think it should be possible to
do e.g.
Context.Response.ContentType = "application/xml";
I haven't tried that however. Let us know whether that approach works
for you.

Ok, I found a solution.
To the web service was a SOAP 1.2 request with the namespace
http://schemas.xmlsoap.org/soap/envelope/
just change it with a SOAP 1.1 request with
xmlns=http://www.w3.org/2003/05/soap-envelope and now it works fine.
Real thanks Martin.
