16  * @class Ext.data.XmlStore
17  * @extends Ext.data.Store
18  * <p>Small helper class to make creating {@link Ext.data.Store}s from XML data easier.
19  * A XmlStore will be automatically configured with a {@link Ext.data.XmlReader}.</p>
20  * <p>A store configuration would be something like:<pre><code>
21 var store = new Ext.data.XmlStore({
22     // store configs
23     autoDestroy: true,
24     storeId: 'myStore',
25     url: 'sheldon.xml', // automatically configures a HttpProxy
26     // reader configs
27     record: 'Item', // records will have an "Item" tag
28     idPath: 'ASIN',
29     totalRecords: '@TotalResults'
30     fields: [
31         // set up the fields mapping into the xml doc
32         // The first needs mapping, the others are very basic
33         {name: 'Author', mapping: 'ItemAttributes > Author'},
34         'Title', 'Manufacturer', 'ProductGroup'
35     ]
36 });
37  * </code></pre></p>
38  * <p>This store is configured to consume a returned object of the form:<pre><code>
