<h2>Important Note</h2>
<p>To extract the text "Jani" from the XML, the syntax is:</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table8">
<tr><td>
<pre>getElementsByTagName("from")[0].childNodes[0].nodeValue</pre>
</td></tr>
</table>
<p>In the XML example there is
only one <from> tag, but you still have to specify the array index [0], because
the XML parser method getElementsByTagName() returns an array of all <from>
nodes. </p>

<h2>Parsing an XML String - A Cross browser Example</h2>

text=text+"<heading>Reminder</heading>";
text=text+"<body>Don't forget me this weekend!</body>";
text=text+"</note>";
