This gives me an error:

var xmlDoc=loadXMLDoc("books.xml");
var books = xmlDoc.getElementByTagName("title");
for(var i = 0; i < books.length; i++){
document.write(xmlDoc.getElementsByTagName("title")[i].childNodes[0].nodeValue + "<br />");
document.write(xmlDoc.getElementsByTagName("author")[i].childNodes[0].nodeValue + "<br />");
document.write(xmlDoc.getElementsByTagName("year")[i].childNodes[0].nodeValue + "<br />");
}
</script>
</head>

However if I remove the line: var books = xmlDoc.getElementByTagName("title"); and replace books.length to say '3' it works.
My XML:

Might it just be that you left out the “s” in xmlDoc.getElementsByTagName(“title”)?
