XML DOM appendChild() method

Definition and Usage

The appendChild() method adds a node after the last child node of the specified element node.

This method returns the new child node.

Syntax:

appendChild(node)
Parameter Description
node Required. The node to be appended.

instance

In all examples, we will use the XML file books.xml, and the JavaScript function loadXMLDoc()

The following code snippet creates and appends a node to the first <book> element, and then outputs all child nodes of the first <book> element:

xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName('book');
var newel,newtext;
for (i=0;i<x.length;i++)
{
newel=xmlDoc.createElement('edition');
newtext=xmlDoc.createTextNode('First');
newel.appendChild(newtext);
x[i].appendChild(newel);
}
//Output all titles and editions
y=xmlDoc.getElementsByTagName("title");
z=xmlDoc.getElementsByTagName("edition");
for (i=0;i<y.length;i++)
{
document.write(y[i].childNodes[0].nodeValue);
document.write(" - Edition: ");
document.write(z[i].childNodes[0].nodeValue);
document.write("
"); }

以上代码的输出:

Everyday Italian - Edition: First
Harry Potter - Edition: First
XQuery Kick Start - Edition: First
Learning XML - Edition: First

注释:Internet Explorer 会忽略节点之间生成的空白文本节点(比如换行字符),而 Mozilla 不这么做。因此,在上面的例子中,我们仅仅处理元素节点(元素节点的 nodeType 等于 1)。
