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.XmlReader}.

+ *

A store configuration would be something like:


+var store = new Ext.data.XmlStore({
+    // store configs
+    autoDestroy: true,
+    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'
+    ]
+});
+ * 

+ *

This store is configured to consume a returned object of the form:


+<?xml version="1.0" encoding="UTF-8"?>
+<ItemSearchResponse xmlns="http://webservices.amazon.com/AWSECommerceService/2009-05-15">
+    <Items>
+        <Request>
+            <IsValid>True</IsValid>
+            <ItemSearchRequest>

+                <SearchIndex>Books</SearchIndex>
+            </ItemSearchRequest>
+        </Request>
+        <TotalResults>203</TotalResults>
+        <TotalPages>21</TotalPages>
+        <Item>

+            <DetailPageURL>
+                http://www.amazon.com/
+            </DetailPageURL>
+            <ItemAttributes>
+                <Author>Sidney Sheldon</Author>

+                <ProductGroup>Book</ProductGroup>

+            </ItemAttributes>
+        </Item>
+    </Items>
+</ItemSearchResponse>
+ * 
+ * An object literal of this form could also be used as the {@link #data} config option.
