[Users] Read KML Attributes and Display in GridPanel

[Stefan Schwarzer]

Hi there,

I would like to read some of the KML attributes and display them in the GridPanel.

It works partly with 

		var store = new GeoExt.data.FeatureStore({
                        .....
		        {name: 'name', type: 'string'},
		        {name: 'Avg_GRIDCO', type: 'string'}
		    ],
		    autoLoad: true
		});



and


	    // create grid panel configured with feature store
	    gridPanel = new Ext.grid.GridPanel({
	        title: "Feature Grid",
	        region: "east",
	        store: store,
	        width: 720,
	        columns: [{
	            header: "Name",
	            width: 200,
	            dataIndex: "name"
	        }, {
	            header: "Value",
	            width: 500,
	            dataIndex: "Avg_GRIDCO"
	        }],
	        sm: new GeoExt.grid.FeatureSelectionModel() 
	    });


But as soon as I want to add more attributes, the KML changes (I use a ArcGIS export script). I would like to add a third column to the GridPanel which would display for example the "query" field as displayed in the KML. But as it now regroups the attributes in "<ExtendedData><SchemaData><SimpleData>...." I don't know how to access these values.
