+ * @class Ext.data.XmlReader
+ * @extends Ext.data.DataReader
+ * Data reader class to create an Array of {@link Ext.data.Record} objects from an XML document
+ * based on mappings in a provided Ext.data.Record constructor.
+ * <p>
+ * The code below lists all configuration options.
+ * <pre><code>
+var myReader = new Ext.data.XmlReader({
+   record: "row",           // The repeated element which contains record information
+   totalRecords: "results", // The element which contains the number of returned records (optional)
+   id: "id"                 // The element within the record that provides an ID for the record (optional)
+}, myRecordDefinition);
+</code></pre>
+ * <p>
+ * This would consume an XML file like this:
+ * <pre><code>
+&lt;?xml?>
+&lt;dataset>
+ &lt;results>2&lt;/results>
+ &lt;row>
+   &lt;id>1&lt;/id>
+   &lt;name>Bill&lt;/name>
+ &lt;/row>
+ &lt;row>
+   &lt;id>2&lt;/id>
+   &lt;name>Ben&lt;/name>
+ &lt;/row>
+&lt;/dataset>
+</code></pre>
+ * @cfg {String} totalRecords The DomQuery path from which to retrieve the total number of records
+ * in the dataset. This is only needed if the whole dataset is not passed in one go, but is being
+ * paged from the remote server.
+ * @cfg {String} record The DomQuery path to the repeated element which contains record information.
+ * @cfg {String} success The DomQuery path to the success attribute used by forms.
+ * @cfg {String} id The DomQuery path relative from the record element to the element that contains
+ * a record identifier value.
+ * @constructor
+ * Create a new XmlReader
+ * @param {Object} meta Metadata configuration options
+ * @param {Mixed} recordType The definition of the data record type to produce.  This can be either a valid
+ * Record subclass created with {@link Ext.data.Record#create}, or an array of objects with which to call
+ * Ext.data.Record.create.  See the {@link Ext.data.Record} class for more details.
