</span> * @author Ed Spencer
* <p>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}.</p>
* <p>A store configuration would be something like:<pre><code>
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 "Item" 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 > Author'},
'Title', 'Manufacturer', 'ProductGroup'
]
});
* </code></pre></p>
* <p>This store is configured to consume a returned object of the form:<pre><code>
&#60?xml version="1.0" encoding="UTF-8"?>
&#60ItemSearchResponse xmlns="http://webservices.amazon.com/AWSECommerceService/2009-05-15">
&#60Items>
&#60Request>
&#60IsValid>True&#60/IsValid>
&#60ItemSearchRequest>
&#60Author>Sidney Sheldon&#60/Author>
&#60SearchIndex>Books&#60/SearchIndex>
&#60/ItemSearchRequest>
&#60/Request>
&#60TotalResults>203&#60/TotalResults>
&#60TotalPages>21&#60/TotalPages>
&#60Item>
&#60ASIN>0446355453&#60/ASIN>
&#60DetailPageURL>
http://www.amazon.com/
&#60/DetailPageURL>
&#60ItemAttributes>
&#60Author>Sidney Sheldon&#60/Author>
&#60Manufacturer>Warner Books&#60/Manufacturer>
&#60ProductGroup>Book&#60/ProductGroup>
&#60Title>Master of the Game&#60/Title>
&#60/ItemAttributes>
&#60/Item>
&#60/Items>
&#60/ItemSearchResponse>
* </code></pre>
* An object literal of this form could also be used as the {@link #cfg-data} config option.</p>
* <p><b>Note:</b> This class accepts all of the configuration options of
* <b>{@link Ext.data.reader.Xml XmlReader}</b>.</p>
