</span> * @author Ed Spencer
 * &lt;p&gt;Small helper class to make creating {@link Ext.data.Store}s from XML data easier.
 * A XmlStore will be automatically configured with a {@link Ext.data.reader.Xml}.&lt;/p&gt;
 * &lt;p&gt;A store configuration would be something like:&lt;pre&gt;&lt;code&gt;
var store = new Ext.data.XmlStore({
    // store configs
    storeId: 'myStore',
    url: 'sheldon.xml', // automatically configures a HttpProxy
    // reader configs
    record: 'Item', // records will have an &quot;Item&quot; tag
    idPath: 'ASIN',
    totalRecords: '@TotalResults'
    fields: [
        // set up the fields mapping into the xml doc
        // The first needs mapping, the others are very basic
        {name: 'Author', mapping: 'ItemAttributes &gt; Author'},
        'Title', 'Manufacturer', 'ProductGroup'
    ]
});
 * &lt;/code&gt;&lt;/pre&gt;&lt;/p&gt;
 * &lt;p&gt;This store is configured to consume a returned object of the form:&lt;pre&gt;&lt;code&gt;
&amp;#60?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
&amp;#60ItemSearchResponse xmlns=&quot;http://webservices.amazon.com/AWSECommerceService/2009-05-15&quot;&gt;
    &amp;#60Items&gt;
        &amp;#60Request&gt;
            &amp;#60IsValid&gt;True&amp;#60/IsValid&gt;
            &amp;#60ItemSearchRequest&gt;
                &amp;#60Author&gt;Sidney Sheldon&amp;#60/Author&gt;

            &amp;#60/ItemSearchRequest&gt;
        &amp;#60/Request&gt;
        &amp;#60TotalResults&gt;203&amp;#60/TotalResults&gt;
        &amp;#60TotalPages&gt;21&amp;#60/TotalPages&gt;
        &amp;#60Item&gt;
            &amp;#60ASIN&gt;0446355453&amp;#60/ASIN&gt;
            &amp;#60DetailPageURL&gt;
                http://www.amazon.com/
            &amp;#60/DetailPageURL&gt;
            &amp;#60ItemAttributes&gt;
                &amp;#60Author&gt;Sidney Sheldon&amp;#60/Author&gt;
                &amp;#60Manufacturer&gt;Warner Books&amp;#60/Manufacturer&gt;
                &amp;#60ProductGroup&gt;Book&amp;#60/ProductGroup&gt;
                &amp;#60Title&gt;Master of the Game&amp;#60/Title&gt;
            &amp;#60/ItemAttributes&gt;
        &amp;#60/Item&gt;
    &amp;#60/Items&gt;
&amp;#60/ItemSearchResponse&gt;
 * &lt;/code&gt;&lt;/pre&gt;
 * An object literal of this form could also be used as the {@link #cfg-data} config option.&lt;/p&gt;
 * &lt;p&gt;&lt;b&gt;Note:&lt;/b&gt; This class accepts all of the configuration options of
 * &lt;b&gt;{@link Ext.data.reader.Xml XmlReader}&lt;/b&gt;.&lt;/p&gt;
