Parsing XML in Javascript getElementsByTagName not working

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");
            $('#tb_actualvsindexedbing_indexed').val($开发者_JS百科(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

I actually just fixed it, what I was doing wrong was when I was trying to set the value of '#tb_actualvsindexedbing_indexed' I was not telling it to use the first entry of the xml, and was just passing it the entire object.

$('#tb_actualvsindexedbing_indexed').val($(result[0].getElementsByTagName("Value")).text());

Thanks for the help anyway.

result = xmlIn.getElementsByTagName("Result")[0]; $('#tb_actualvsindexedbing_indexed').val($(result.getElementsByTagName("Value")[0]).text());

element = element; elements = array of elements
