示例
以下代码片段将
"books.xml" 加载到 xmlDoc 中,并将具有命名空间的元素节点添加到每个<book>元素:
<!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, newel, newtext, xmlDoc, txt;
xmlDoc = xml.responseXML;
txt = "";
x = xmlDoc.getElementsByTagName("book");
for (i = 0; i < x.length; i++) {
newel = xmlDoc.createElementNS("p", "edition");
newtext = xmlDoc.createTextNode("First");
newel.appendChild(newtext);
x[i].appendChild(newel);
}
y = xmlDoc.getElementsByTagName("title");
z = xmlDoc.getElementsByTagNameNS("p","edition");
for (i = 0; i < y.length; i++) {
txt += y[i].childNodes[0].nodeValue +
" - " +
z[i].childNodes[0].nodeValue +
" edition." +
" Namespace: " +
z[i].namespaceURI + "<br>";
}
document.getElementById("demo").innerHTML = txt;
}
</script>
</body>
</html>
