Consume web service in javascript

[forums UseR]

Hello,

Can anybody let me know how to consume web service in javascript...

The output of the webservice is another XML file. I am new to XPath. Can you also let me know how to use XPath to get the data out from the web service output, and show it in a simple table with 3 columns...

Here is the output from the web service:
Code:

<?xml version='1.0' standalone='yes'?>
<list>
  <sales>
    <soNum>123456789</soNum>
    <status>shipped</status>
    <soldTo>Xyz</soldTo>
  </sales>
  <sales>
    <soNum>987654321</soNum>
    <status>scheduled</status>
    <soldTo>Abc</soldTo>
  </sales>
</list>

Thanks
Srinivas

Thanks for your reply!

The reason is I am working on Yahoo widget, where the only option is to use Javascript.

Unless, if you have better thoughts of using a different language underneath the widget...

Hello,

I am using this blog to script the webservice call...,

I get a "window is not defined" error, in the "prototype.js" library at line 399.

Here is the code am using

<action trigger="onLoad">      
<!--
include("prototype.js");
include("ws.js");      
mainWindow.visible = true; 
function getSalesXml(name, container) {
  var call = new WS.Call('<url to the wsdl>'); 
  var nsuri = 'http://example';
  var qn_op = new WS.QName('<methodname>',nsuri);
  var qn_op_resp = new WS.QName('sayHelloResponse',nsuri);  
  call.invoke_rpc(
    qn_op,
    new Array(
      {name:'userId',value:<username>, name:'pwd',value:<password>}
    ),null,
    function(call,envelope) {
      var ret = 
        envelope.get_body().get_all_children()[0].
          get_all_children()[0].get_value();
      container.innerHTML = ret;
      $('soap').innerHTML = arguments[2].escapeHTML();
    }
  );
}
-->	
</action>	

Is there a problem with my code above.

thanks
Srinivas
