������� myFunction(xhttp);
��� }
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
function myFunction(xml) {
var x, i, att, xmlDoc,
txt;
xmlDoc = xml.responseXML;
txt = "";
x = xmlDoc.getElementsByTagName('book');
for (i = 0; i < x.length; i++) {
att = x.item(i).attributes.getNamedItem("category");
txt += att.value + "<br>";
