<h1>HTML DOM Nodes</h1>

<p class="intro">In the DOM, everything in an HTML document is a node.</p>
<hr />
<h2>Nodes</h2>
<p>According to the DOM, everything in an HTML document is a node.</p>
<p>The DOM says:</p>
<ul>
<li>The
entire document is a document node</li>
<li>Every HTML tag is an element node</li>
<li>The text in the HTML elements are text
nodes</li>
<li>Every HTML attribute is an attribute node</li>
<li>Comments are comment nodes</li>
</ul>
<hr />
<h2>DOM Example</h2>
<p>Look at the following HTML document:</p>
<table class="ex" id="table1" cellspacing="0" width="100%" border="1">
<tr>
<td valign="top">
<pre><html>
<head>
<title>DOM Tutorial</title>
</head>
<body>
<h1>DOM Lesson one</h1>
<p>Hello world!</p>
</body>
</html></pre>
</td>
</tr>
</table>
<p>The root node in the HTML above is <html>. All other nodes in the document
are contained within <html>.</p>
<p>The <html> node has two child nodes; <head> and <body>.</p>
<p>The <head> node holds a <title> node. The <body> node holds a <h1> and <p>
node.</p><hr />
<h2>Text is Always Stored in Text Nodes</h2>
<p>A common error in DOM processing is to expect an element node to contain
text. </p>
<p>However, the text of an element node is stored in a text node.</p>
<p>In this example: <b><title>DOM Tutorial</title></b>, the element node
<title>, holds a text node with the value "DOM Tutorial". </p>
<p>"DOM Tutorial" is <b>not</b> the value of the <title> element!</p>
<p>However, in the HTML DOM the value of the text node can be accessed by the
<b>innerHTML</b> property.</p>
<p>You can read more about the innerHTML property in a later chapter.</p>
