XML DOM item() Method

NodeList Object Reference NodeList Object

Definition and Usage

The item() method returns the node at the specified index in a node list.

Syntax

item(index)

Parameter Description
index The index

Tips and Notes

Note: Firefox, and most other browsers, will treat empty white-spaces or new lines as text nodes, Internet Explorer will not. So, in the example below, we have a function that checks the type of the nodes.

Element nodes has a nodeType of 1, so if the child node is not an element node, it moves to the next node, and checks if this node is an element node. This way, the result will be correct in all browsers.

Tip: To read more about the differences between browsers, visit our DOM Browsers chapter in our XML DOM Tutorial.

Example

The following code fragment loads "books.xml" into xmlDoc using loadXMLDoc() and loops through all child element nodes of the <bookstore> element:

Example

xmlDoc=loadXMLDoc("books.xml");

x=xmlDoc.documentElement.childNodes;

for (i=0;i<x.length;i++)
{
//Display only element nodes
if (x.item(i).nodeType==1)
  {
  document.write(x.item(i).nodeName);
  document.write("<br />");
  }
}

Output:

book
book
book
book
