Wonder if someone can get me on the right track. I have a web service that
returns the xml representation of some data. This returned data is loaded
in the client (i.e. 6) into a msxml4 object. The data is then rendered to
html with a xsl transformation client side. This works great and how things
will stay. Now I need to get the data the other way to a web service.

When the user clicks on Save the client side xml is updated with the values
they have changed. I then need to post this back to another web service
that will expect this data. Now obviously I can not simply pas the xml as
string on the querystring because you run into encoding problems if the user
has entered in & > or < values for example, and yes I have to allow for
these.

So my question is how to send the xml back to a web service via Jscript and
get a xml response back from the service? Do I need to wrap it in a soap
package or something similar?

Any help would be appreciated.

Cheers
Keith

You can do a HTTP POST request where the XML is sent in the body of the
HTTP request:
var httpRequest = new ActiveXObject('Msxml2.XMLHTTP.4.0');
httpRequest.open('POST', 'whatever.asp', true);
httpRequest.onreadystatechange = function () {
if (httpRequest.readyState == 4) {
// process httpRequest.responseXML here
}
};
httpRequest.send(putMsxml2.DOMDocument.4.0Here);

If you really want to send the data to a web service then of course you
might need to use SOAP, then the web service behaviour should help you
on the client, seach http://msdn.microsoft.com/ for that.

Thanks Martin,

I got as far as you mentioned last night but my problem is getting my web
service to accept the incomming data. Nothing like a weekend learner curve!
