    Convert External XML Timestamp to Readable HTML Display with JScript

    Greetings all,

    I have an issue where I am having trouble converting an ISO8601 timestamp into a readable value. These timestamp values are located and grabbed from an external XML file and I need a simple way to convert it into a readable value before posting on an HTML page.

    Here is the code I'm initially pulling the data with:

    Code:
    <span id="Created0"></span>
    <span id="Created1"></span>
    <span id="Created2"></span>
    etc...
    
    <script>
    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","externallink=xml",false);
    xmlhttp.send();
    xmlDoc=xmlhttp.responseXML;
    
    var i=0,d;
    while (d=document.getElementById("Created"+i)) d.innerHTML=xmlDoc.getElementsByTagName("Created")[i++].childNodes[0].nodeValue;
    </script>
    And an example of the external code from the XML file:

    Code:
    <PostItems>
          <member>
            <Author>user:chayavic</Author>
            <Body>@joelboss just saved someone's Christmas. What have you done today? There's still time. #c2alerts</Body>

    It appears to grab and display the "Created" items perfectly, but how would I render them out of the ISO8601 format into something readable, say "December 13th, 8:32pm" before actually defining it as a span? (Or even AFTER it defines them, then just modifies the value?)

    Been banging my head against a wall trying to figure this one out Any help is appreciated!

    Take a look at the Date object.
    Code:
    var dateString = '2012-12-12T23:41:50.948Z';
    var date = new Date(dateString);
    alert(dateString+'\n\n'+date.toLocaleString());
