<p>Firefox, and some other browsers, will treat empty white-spaces or new lines 
as text nodes, Internet Explorer will not</p>
<p>The following code fragment displays how many child nodes the root element 
(of books.xml) has:</p>

<table width="100%" border="1" class="ex" cellspacing="0" id="table21">
  <tr>
    <td>
	<pre>xmlDoc=loadXMLDoc(&quot;books.xml&quot;);</pre>
	<pre>x=xmlDoc.documentElement.childNodes;
document.write(&quot;Number of child nodes: &quot; + x.length);</pre>
    </td>
  </tr>
</table>
<p>Example explained:</p>
<ol>
	<li>Load &quot;<a target="_blank" href="books.xml">books.xml</a>&quot; 
	into xmlDoc using <a href="dom_loadxmldoc.asp">loadXMLDoc()</a> </li>
	<li>Get the child nodes of the root element</li>
	<li>Output the number of child nodes. The result is different depending on 
	which browser you use. Firefox will alert 9 child nodes, while Internet 
	Explorer will alert 4.</li>
</ol>

<h2>Ignore Empty Text Between Elements</h2>
<p>To ignore empty text nodes between element nodes, you can check the node type. An element node 
has type 1:</p>

<table width="100%" border="1" class="ex" cellspacing="0" id="table27">
  <tr>
    <td>
<pre>xmlDoc=loadXMLDoc(&quot;books.xml&quot;);</pre>
<pre>x=xmlDoc.documentElement.childNodes;</pre>
<pre>for (i=0;i&lt;x.length;i++)
{ 
if (x[i].nodeType==1)
  {// only process element nodes 
  document.write(x[i].nodeName);
  document.write(&quot;&lt;br /&gt;&quot;);
  } 
}</pre>
    </td>
  </tr>
</table>

<p>Example explained:</p>
<ol>
	<li>Load &quot;<a target="_blank" href="books.xml">books.xml</a>&quot; 
	into xmlDoc using <a href="dom_loadxmldoc.asp">loadXMLDoc()</a> </li>
	<li>Get the child nodes of the root element</li>
	<li>For each child node, check the node type of the node. If the node type 
	is &quot;1&quot; it is an element node</li>
	<li>Output the name of the node if it is an element node</li>
</ol>
