示例
<!DOCTYPE html>
<html>
<body>
<p id="demo"></p>
<script>
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
myFunction(xhttp);
}
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
function myFunction(xml) {
var x, i, xmlDoc, txt;
xmlDoc = xml.responseXML;
txt = "";
x = xmlDoc.childNodes;
for (i = 0; i < x.length; i++) {
txt += "Nodename: " + x[i].nodeName +
" (nodetype: " + x[i].nodeType + ")<br>";
}
document.getElementById("demo").innerHTML = txt;
}
</script>
</body>
</html>
尝试一下
上面代码的输出将是:
Nodename: bookstore (nodetype: 1)
输出IE9及更早版本:
Nodename: xml (nodetype: 7)
Nodename: bookstore (nodetype: 1)
