            Data reader class to create an Array of <a ext:cls="Ext.data.Record" href="output/Ext.data.Record.html">Ext.data.Record</a> objects from an XML document
based on mappings in a provided Ext.data.Record constructor.<br><br>
<p>
<em>Note that in order for the browser to parse a returned XML document, the Content-Type
header in the HTTP response must be set to "text/xml".</em>
<p>
Example code:
<pre><code>var Employee = Ext.data.Record.create([
   {name: <em>'name'</em>, mapping: <em>'name'</em>},     <i>// <em>"mapping"</em> property not needed <b>if</b> it's the same as <em>"name"</em></i>
   {name: <em>'occupation'</em>}                 <i>// This field will use <em>"occupation"</em> as the mapping.</i>
]);
<b>var</b> myReader = <b>new</b> Ext.data.XmlReader({
   totalRecords: <em>"results"</em>, <i>// The element which contains the total dataset size (optional)</i>
   record: <em>"row"</em>,           <i>// The repeated element which contains row information</i>
   id: <em>"id"</em>                 <i>// The element within the row that provides an ID <b>for</b> the record (optional)</i>
}, Employee);</code></pre>
<p>
This would consume an XML file like this:
<pre><code>&lt;?xml version=<em>"1.0"</em> encoding=<em>"UTF-8"</em>?>
&lt;dataset>
 &lt;results>2&lt;/results>
 &lt;row>
   &lt;id>1&lt;/id>
   &lt;name>Bill&lt;/name>
   &lt;occupation>Gardener&lt;/occupation>
 &lt;/row>
 &lt;row>
   &lt;id>2&lt;/id>
   &lt;name>Ben&lt;/name>
   &lt;occupation>Horticulturalist&lt;/occupation>
 &lt;/row>
