Tips and Notes
Note: Firefox and most other browsers, the empty spaces between the nodes will generate or wrap as text nodes, while Internet Explorer will ignore whitespace text nodes between nodes generated.Thus, in the example below, we'll use a function that checks the node type of the last child node.
Node type element node is 1, so if the first child node is not an element node, it will move to the next node, and checks if this node is an element node. The whole process will continue until the first element child node is found. Through this method, we can get the right results in all browsers.
Tip: For more information about browser differences, please visit us in our XML DOM tutorial DOM browser section.
Examples
The following code fragment uses loadXMLDoc () to " the Books.xml " into xmlDoc, and get the last child node:
Examples
function get_lastchild(n)
{
x=n.lastChild;
while (x.nodeType!=1)
{
x=x.previousSibling;
}
return x;
}
xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.documentElement;
lastNode=get_lastchild(x);
for (i=0;i<lastNode.childNodes.length;i++)
{
if (lastNode.childNodes[i].nodeType==1)
{
//Process only element nodes
document.write(lastNode.childNodes[i].nodeName);
document.write(" = ");
document.write(lastNode.childNodes[i].childNodes[0].nodeValue);
document.write("
");
}
}
The code above will output:
