Hi, I am trying to parse the following XML with javascript:

<?xml version='1.0' encoding='UTF-8'?>
<ResultSet>
    <Result>
        <URL>www.asd.com</URL>
        <Value>10500</Value>
    </Result>
</ResultSet>

The XML is generated by a PHP script to get how many pages are indexed in Bing.

My javascript function is as follows:

function bingIndexedPages() {
    ws_url = "http://archreport.epiphanydev2.co.uk/worker.php?query=bingindexed&domain="+$('#hidden_the_domain').val();
    $.ajax({
        type: "GET",
        url: ws_url,
        dataType: "xml",
        success: function(xmlIn){
            alert('success');
            result = xmlIn.getElementsByTagName("Result");
            $('#tb_actualvsindexedbing_indexed').val($(result.getElementsByTagName("Value")).text());
            $('#img_actualvsindexedbing_worked').attr("src","/images/worked.jpg");          
        },
        error: function() {$('#img_actualvsindexedbing_worked').attr("src","/images/failed.jpg");}
    });
}

The problem I'm having is firebug is saying: 'result.getElementsByTagName is not a function'

Can you see what is going wrong?

Thanks
