XML http request with a URL

I want to retrieve an XML from a URL and store it in a variable xmlDoc.

I have the following:

if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
                xmlhttp=new XMLHttpRequest();
            } else {// code for IE6, IE5
                xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
            }

            xmlhttp.open("GET","localhost:8080/rest/xml",false);
            xmlhttp.send();
            xmlDoc=xmlhttp.responseXML;

But I am not getting the XML file, is there something I need to add?

before sending, attach a callback like this.

  xmlhttp.onreadystatechange=function()
      {
      if (xmlhttp.readyState==4 && xmlhttp.status==200)
        {
        xmlDoc=xmlhttp.responseText;
        }else if (xmlhttp.readyState==4 && xmlhttp.status != 200)
        {
         alert("error-" + xmlhttp.responseText);
        }
      }

The open method is passing false as the last parameter, making this a synchronous request. The OP's original code is correct, except for one thing: the URL.

xmlhttp.open("GET","http://localhost:8080/rest/xml",false);

Or if you want to make the URL agnostic to the protocol of the current page:

xmlhttp.open("GET","//localhost:8080/rest/xml",false);
