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 | The node to be appended is required. |
Example
In all examples, we will use the XML file books.xml, and the JavaScript function loadXMLDoc().
Below is a code snippet that 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("<br />");
{}
The output of the above code:
Everyday Italian - Edition: First Harry Potter - Edition: First XQuery Kick Start - Edition: First Learning XML - Edition: First
Note:Internet Explorer will ignore the generated whitespace text nodes between nodes (such as newline characters), while Mozilla does not. Therefore, in the above example, we only handle element nodes (the nodeType of element nodes is equal to 1).
