 * &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;
