xmlDoc.async = false;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode <> 0) {
   var myErr = xmlDoc.parseError;
   alert("You have error " + myErr.reason);
} else {
   nodePublishDate = xmlDoc.createAttribute("PublishDate");
   nodePublishDate.value = String(Date());
   nodeBook = xmlDoc.selectSingleNode("//book");
   nodeBook.setAttributeNode(nodePublishDate);
   alert(nodeBook.getAttribute("PublishDate"));
