Safari 4 Java/XML/HTML problem

Hello,

So I have been making a website for a friend that requires posts to be loaded via an external XML sheet on the server. I am more or less using w3schools example (http://www.w3schools.com/xml/xml_to_html.asp). The problem is that it does not load using safari 4 or google chrome web browser. is there any reasons? I have been trying to google it but I am not sure exactly what I am looking for.

w3schools code that does not work in chrome or safari 4

<html>
<body>

<script type=“text/javascript”>
var xmlDoc=null;
if (window.ActiveXObject)
{// code for IE
xmlDoc=new ActiveXObject(“Microsoft.XMLDOM”);
}
else if (document.implementation.createDocument)
{// code for Mozilla, Firefox, Opera, etc.
xmlDoc=document.implementation.createDocument("","",null);
}
else
{
alert(‘Your browser cannot handle this script’);
}
if (xmlDoc!=null)
{
xmlDoc.async=false;
xmlDoc.load(“cd_catalog.xml”);

document.write("<table border=‘1’>");

var x=xmlDoc.getElementsByTagName(“CD”);
for (i=0;i<x.length;i++)
{
document.write("<tr>");
document.write("<td>");
document.write(
x*.getElementsByTagName(“ARTIST”)[0].childNodes[0].nodeValue);
document.write("</td>");

document.write("<td>");
document.write(
x*.getElementsByTagName(“TITLE”)[0].childNodes[0].nodeValue);
document.write("</td>");
document.write("</tr>");
}
document.write("</table>");
}
</script>

</body>
</html>

Thank you in advance for your help!
