Getting all headers with `getAllResponseHeaders()`

The above string is obtained by the following line of code:

headersStr = xmlHttp.getAllResponseHeaders();

Processing of this string to be displayed in a table is done by the following code:

var headers = headersStr.split(/\n/);
var s = "<table border='1' cellpadding='5'>" +
   "<tr><th>Header</th> <th>Value</th></tr>";
for (var i=0; i<headers.length; i++)
  if (headers[i].length > 0)
  {
    var header = headers[i].substring(0,headers[i].indexOf(":"));
    var value = headers[i].substring(headers[i].indexOf(":")+1,
      headers[i].length);
    s += "<tr class='yello'><td>" + header +
      "</td><td>" + value + "</td></tr>";
  }
s += "</table>";
var div = document.getElementById("headers2");
div.innerHTML = s;
