XML DOM removeChild() method
Definition and Usage
The removeChild() method deletes a child node.
If successful, returns the deleted node, otherwise returns NULL.
Syntax:
elementNode.removeChild(node)
| Parameter | Description |
|---|---|
| node | Required. Specifies the child node to be deleted. |
Example
In all examples, we will use the XML file books.xml, as well as the JavaScript function loadXMLDoc().
The following code snippet deletes the last child node of the first <book> element:
//check if last child node is an element node
function get_lastchild(n)
{
x=n.lastChild;
while (x.nodeType!=1)
{
x=x.previousSibling;
}
return x;
}
xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName("book")[0];
deleted_node=x.removeChild(get_lastchild(x));
document.write("Node removed: " + deleted_node.nodeName);
Output:
Node removed: price
Note:Internet Explorer will ignore the generated whitespace text nodes between nodes (such as newline symbols), while Mozilla will not do so. Therefore, in the above example, we created a function to get the correct child element.
