Question

this is a partial code:

function readXmlUsingXPath(i,guid, xpath) {
    var xmlDoc = loadXML("gameFeed.aspx?guid=" + guid);
    if (xmlDoc == null) { document.getElementById(guid).innerHTML = "UPDATING"; return }
    else { };
    i.innerHTML = xmlDoc.selectNodes(xpath)[0].text;
}

window.onload = function () {
    for (var i = 0; i < document.getElementsByTagName('jackpot').length; i++) {
        var guid = document.getElementsByTagName('jackpot')[i].getAttribute('data-g').split('|')[0];
        var xpath = document.getElementsByTagName('jackpot')[i].getAttribute('data-g').split('|')[1];
        readXmlUsingXPath(document.getElementsByTagName('jackpot')[i],guid, xpath);
    }
}

basicly, what i want to do is pass the element from the onload function, to the readXmlUsingXpath function, so i could change it.
but i get an unknown runtime error…

as asked, some sample html:

<li>
<a href="/gamepath/"><span>gameTitle</span>
<span><jackpot data-g="<%=game.Guid %>|<%=game.GamingProperties.JackpotFeedXpath %>">UPDATING . . .</jackpot></span>
</a>
</li>

ok, so i modified the code a bit,
and made it simpler.

now it works as its supposed to.

function loadXMLDoc(guid,xpath,i) {

    var xmlhttp;
    if (window.XMLHttpRequest) {xmlhttp = new XMLHttpRequest();}
    else {xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");}
    xmlhttp.async = true;
    xmlhttp.onreadystatechange = function () {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
            i.innerHTML = xmlhttp.responseXML.selectNodes(xpath)[0].text;
        }
    }
    xmlhttp.open("GET", "gameFeed.aspx?guid=" + guid, true);
    xmlhttp.send();
}

var tags = document.getElementsByTagName("pre");
for (var i = 0; i < tags.length; i++) {
    var data = tags[i].getAttribute('data-g').split('|'), guid = data[0], xpath = data[1];
    loadXMLDoc(guid,xpath,tags[i]);
}
