Display simple XML data into an HTML page

i'm sorry if this is a very basic question but i'm really stuck here and i don't have much time. so i created an xml file with data in it and want to display it in html using javascript, but all i get is a blank page. this is my xml file:

<?xml version="1.0" encoding="UTF-8"?>

<text>
    <content>  a random text </content>
</text>

and that's my html file xml

    <script>
        document.write("begin");
        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","text.xml",false);
        xmlhttp.send();
        xmlDoc=xmlhttp.responseXML; 

        var x=xmlDoc.getElementsByTagName("text");
        document.write(x[i].getElementsByTagName("content")    [0].childNodes[0].nodeValue);
    </script>

</body>
</html>

maybe it uses httpRequest so it needs a server, but i tried apache and it did not work. thanks for helping me
