示例
以下代码片段将
"books.xml" 加载到 xmlDoc 中,克隆第一个<book>节点,然后将其添加到节点列表的末尾:
<!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, cloneNode, i, xmlDoc, txt;
xmlDoc = xml.responseXML;
txt = "";
x = xmlDoc.getElementsByTagName('book')[0];
cloneNode = x.cloneNode(true);
xmlDoc.documentElement.appendChild(cloneNode);
y = xmlDoc.getElementsByTagName("title");
for (i = 0; i < y.length; i++) {
txt += y[i].childNodes[0].nodeValue + "<br>";
}
document.getElementById("demo").innerHTML = txt;
}
</script>
</body>
</html>
