    I am trying to obtain a list of links on a webpage. I have the below code which outputs only one link

    I can obtain each link by changing elms[0] however i cannot loop to obtain them all

    Any assistance is welcome
     
<html>
<head>
<script type="text/javascript">
function loadXMLDoc()
{
var xmlhttp;
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","[URL]http://www.comp.dit.ie",false[/URL]);
xmlhttp.send();

document.getElementById("myDiv").innerHTML=xmlhttp.responseText;
//txt=document.getElementById("footer").innerHTML;
//document.write("<p>The text from the intro paragraph: " + txt + "</p>");
 
var elms = document.getElementsByTagName("a");
//for (int i=0; i<elems.length; i++){
//document.write("<p>The text from the intro paragraph: " + elms[i] + "</p>");
//document.write("<p>The text from the intro paragraph: " + elms.length + "</p>");
document.write("<p>The text from the intro paragraph: " + elms[0] + "</p>");
document.write("<p>The text from the intro paragraph: " + elms[1] + "</p>");
document.write("<p>The text from the intro paragraph: " + elms[2] + "</p>");

}
</script>
</head>
<body>
<div id="myDiv"><h2>Load Page Selection Data</h2></div>
<button type="button" onclick="loadXMLDoc()">Load Data</button>
</body>
</html>
