  24  * &lt;p&gt;Small helper class to make creating {@link Ext.data.Store}s from XML data easier.

  28     // store configs
  29     autoDestroy: true,
  30     storeId: 'myStore',
  31     url: 'sheldon.xml', // automatically configures a HttpProxy
  32     // reader configs
  33     record: 'Item', // records will have an &quot;Item&quot; tag
  34     idPath: 'ASIN',
  35     totalRecords: '@TotalResults'
  36     fields: [
  37         // set up the fields mapping into the xml doc
  38         // The first needs mapping, the others are very basic
