<h2>E4X Example</h2>
<p>As an example, we will work with an XML document that represents an order.</p>
<p>The XML document looks like this:</p>
<table class="ex" width="100%" border="1" cellspacing="0"><tr><td>
<pre><order>
<date>2005-08-01</date>
<customer>
<firstname>John</firstname>
<lastname>Johnson</lastname>
</customer>
<item>
<name>Maxilaku</name>
<qty>5</qty>
<price>155.00</price>
</item>
</order></pre>
</td></tr></table>
<p>If we had this XML document stored in a string called txt, we
could load it into an XML object variable called order, by writing the following
JavaScript statement:</p>
<table class="ex" width="100%" border="1" cellspacing="0" id="table1"><tr><td>
<pre>var order = new XML(txt)</pre>
</td></tr></table>
<p>Or we could assign the XML text directly to the XML object variable: </p>
<table class="ex" width="100%" border="1" cellspacing="0" id="table2"><tr><td>
<pre>var order = new XML()</pre>
<pre>order=<order id="555">
<date>2005-08-01</date>
<customer>
<firstname>John</firstname>
<lastname>Johnson</lastname>
</customer>
<item>
<name>Maxilaku</name>
<qty>5</qty>
<price>155.00</price>
</item>
</order></pre>
</td></tr></table>
<br />
<hr />
<h2>Working With the Data</h2>
<p>Calculate the price: </p>
<table class="ex" width="100%" border="1" cellspacing="0" id="table4"><tr><td>
<pre>var total=order.item.qty * order.item.price</pre>
</td></tr></table>
<p>Display the customers full name: </p>
<table class="ex" width="100%" border="1" cellspacing="0" id="table3"><tr><td>
<pre>document.write(order.customer.lastname)
document.write(",")
document.write(order.customer.firstname)</pre>
</td></tr></table>
<p>Add a new item: </p>
<table class="ex" width="100%" border="1" cellspacing="0" id="table5"><tr><td>
<pre>order.item+=
<item>
<name>Pavlova</name>
<qty>10</qty>
<price>128.00</price>
</item></pre>
</td></tr></table>
<p>Display the order id: </p>
<table class="ex" width="100%" border="1" cellspacing="0" id="table6"><tr><td>
<pre>document.write(order.@id)</pre>
</td></tr></table>
<p>Calculate the total price, when the order has many items: </p>
