- * @class Ext.data.XmlReader

- * <p>Data reader class to create an Array of {@link Ext.data.Record} objects from an XML document
- * based on mappings in a provided {@link Ext.data.Record} constructor.</p>
- * <p><b>Note</b>: that in order for the browser to parse a returned XML document, the Content-Type
- * header in the HTTP response must be set to "text/xml" or "application/xml".</p>
- * <p>Example code:</p>
- * <pre><code>
-var Employee = Ext.data.Record.create([
- {name: 'name', mapping: 'name'}, // "mapping" property not needed if it is the same as "name"
- {name: 'occupation'} // This field will use "occupation" as the mapping.
-]);
-var myReader = new Ext.data.XmlReader({
- totalRecords: "results", // The element which contains the total dataset size (optional)
- record: "row", // The repeated element which contains row information
- id: "id" // The element within the row that provides an ID for the record (optional)
-}, Employee);
-</code></pre>
- * <p>
- * This would consume an XML file like this:
- * <pre><code>
-<?xml version="1.0" encoding="UTF-8"?>
-<dataset>
- <results>2</results>
- <row>
- <id>1</id>
- <name>Bill</name>
- <occupation>Gardener</occupation>
- </row>
- <row>
- <id>2</id>
- <name>Ben</name>
- <occupation>Horticulturalist</occupation>
- </row>
-</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} idPath 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 {Object} recordType Either an Array of field definition objects as passed to
- * {@link Ext.data.Record#create}, or a Record constructor object created using {@link Ext.data.Record#create}.
