示例
以下代码片段将
"books.xml" 加载到 xmlDoc 中,并从所有<book>元素中删除 "category" 属性节点:
<!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, attnode, old_att, xmlDoc, txt;
xmlDoc = xml.responseXML;
txt = "";
x = xmlDoc.getElementsByTagName('book');
for (i = 0; i < x.length; i++) {
while (x[i].attributes.length > 0) {
attnode = x[i].attributes[0];
old_att = x[i].removeAttributeNode(attnode);
txt += "Removed: " + old_att.nodeName +
": " + old_att.nodeValue + "<br>";
}
}
document.getElementById("demo").innerHTML = txt;
}
</script>
</body>
</html>
