示例
以下代码片段将
"books.xml" 加载到 xmlDoc 中并创建一个节点(<edition>),并将其追加到第一个<book>节点的最后一个子节点之后:
<!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, y, i, newElement, txt, xmlDoc;
xmlDoc = xml.responseXML;
newElement = xmlDoc.createElement("edition");
x = xmlDoc.getElementsByTagName("book")[0]
x.appendChild(newElement);
// Display all elements
xlen = x.childNodes.length;
y = x.firstChild;
txt = "";
for (i = 0; i < xlen; i++) {
if (y.nodeType == 1) {
txt += y.nodeName + "<br>";
}
y = y.nextSibling;
}
document.getElementById("demo").innerHTML = txt;
}
</script>
</body>
</html>
