XML DOM firstChild Property

Definition and Usage

The firstChild property returns the first child node of the specified node.

Syntax

Tips and Notes

Note: Firefox and most other browsers will treat spaces or newlines between nodes as text nodes, while Internet Explorer will ignore whitespace text nodes generated between nodes. Therefore, in the following example, we will use a function to check the node type of the first child node.

The node type for element nodes is 1. Thus, if the first child node is not an element node, it will move to the next node and continue checking if this node is an element node. This process will continue until the first element child node is found. By using this method, we can obtain correct results in all browsers.

Tip: For more information on browser differences, please visit our DOM Browsers section in our XML DOM tutorial.

Example

The following code snippet uses loadXMLDoc() to load "books.xml" into xmlDoc and displays the node name and node type of the first child node:

Example

// Get the first child node name and value
function get_firstchild(n)
{
  x=n.firstChild;
  while (x.nodeType!=1)
  {
    x=x.nextSibling;
  }
  return x;
}

xmlDoc=loadXMLDoc("books.xml");

x=get_firstchild(xmlDoc);
document.write("Nodename: " + x.nodeName);
document.write("nodetype: " + x.nodeType);

Output:

Nodename: bookstore nodetype: 1
