xmlDoc=loadXMLDoc("books.xml");

x=xmlDoc.getElementsByTagName("book");

for(i=0;i<x.length;i++)
{
x.item(i).setAttribute("edition","first");
}

//Output book title and edition value
x=xmlDoc.getElementsByTagName("title");
for (i=0;i<x.length;i++)
{
document.write(x[i].childNodes[0].nodeValue);
document.write(" - Edition: ");
document.write(x[i].parentNode.getAttribute('edition'));

}
