替换节点

添加节点

创建新的元素节点

createElement() 方法创建新的元素节点：

例子 1

newElement = xmlDoc.createElement("edition");

xmlDoc.getElementsByTagName("book")[0].appendChild(newElement);

运行实例 »

点击 "运行实例" 按钮查看在线实例

例子解释：

假设 books.xml 已被加载到 xmlDoc 中
创建一个新的元素节点
将这个元素节点追加到第一个元素

例子 2

循环遍历并向所有元素添加一个元素：

for (i = 0; i < xLen; i++) { 
    newEle = xmlDoc.createElement("edition");
    newText = xmlDoc.createTextNode("第一版");
    newEle.appendChild(newText);
    x[i].appendChild(newEle);
}

创建新的属性节点

createAttribute() 用于创建新的属性节点：

例子 1

newAtt = xmlDoc.createAttribute("edition");
newAtt.nodeValue = "第一版";

xmlDoc.getElementsByTagName("title")[0].setAttributeNode(newAtt);
