[jQuery] jquery code works with firefox but not ie.

[silk.odyssey]

I have the following code that works in firefox and google chrome
using jquery 1.2.6.

function setUpClient()
{
        $.post("http://localhost/gestivov2/include/ajax/getclients.php";, {},
        function(data){
        $('#left_items').empty();
                //alert(data);
                $("client",data).each(function(id) {
                        client = $("client",data).get(id);
                        $("#left_items").append("<li 
id='"+$("id",client).text()+"'><a
href='#'>"+$("name",client).text()+"</a></li>");
                });
        })
}

It doesn't work with internet explorer 7, 8 beta nor 6. If I uncomment
the alert code, the xml data gets displayed so it looks like the code
within the each block is not being executed. What am i doing wrong?
