示例
以下代码片段将
"books.xml" 加载到 xmlDoc 中,并向所有<book>元素添加 “edition” 属性:
<!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, z, i, xLen, newAtt, xmlDoc, txt;
xmlDoc = xml.responseXML;
x = xmlDoc.getElementsByTagName('book');
xLen = x.length;
for (i = 0; i < xLen; i++) {
newAtt = xmlDoc.createAttribute("edition");
newAtt.value = "first";
x[i].setAttributeNode(newAtt);
}
// Output all "edition" attribute values
txt = "";
for (i = 0; i < x.length; i++) {
txt += "Edition: " + x[i].getAttribute("edition") + "<br>";
}
document.getElementById("demo").innerHTML = txt;
}
</script>
</body>
</html>
