/**
* @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>
<?xml version="1.0" encoding="UTF-8"?>
<ItemSearchResponse xmlns="http://webservices.amazon.com/AWSECommerceService/2009-05-15">
<Items>
<Request>
<IsValid>True</IsValid>
<ItemSearchRequest>
<Author>Sidney Sheldon</Author>
<SearchIndex>Books</SearchIndex>
</ItemSearchRequest>
</Request>
<TotalResults>203</TotalResults>
<TotalPages>21</TotalPages>
<Item>
<ASIN>0446355453</ASIN>
<DetailPageURL>
http://www.amazon.com/
</DetailPageURL>
<ItemAttributes>
<Author>Sidney Sheldon</Author>
<Manufacturer>Warner Books</Manufacturer>
<ProductGroup>Book</ProductGroup>
<Title>Master of the Game</Title>
</ItemAttributes>
</Item>
</Items>
</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>
