XML DOM lastChildProperty

Document object

Definition and Usage

The lastChild property returns the last child node of the document.

Syntax

documentObject.lastChild

Tips and notes

Note:Firefox and most other browsers treat empty spaces or line breaks generated between nodes as text nodes, while Internet Explorer ignores blank text nodes generated between nodes. Therefore, in the example below, we will use a function to check the node type of the last child node.

The node type of an element node is 1, so if the last child node is not an element node, it moves to the previous node, and then continues to check whether this node is an element node. This process continues until the last element child node is found. In this way, we can get correct results in all browsers.

Example

//Get the name and value of the last child node function get_lastchild(n) { x=n.lastChild; while (x.nodeType!=1) { x=x.previousSibling; } return x; } xmlDoc=loadXMLDoc("books.xml"); x=get_lastchild(xmlDoc); document.write("Nodename: " + x.nodeName); document.write(" (nodetype: " + x.nodeType + ")<br>");

Output:
