XMLReader Filtern

[Bolle87]

Hi,

I've got a little problem, but I do not find any solutions for that!

I use the Ext.data.XMLReader to load a XML file to an Ext.data.Store.

But I want filter the XMl, so that for example only the tags where city=Berline are loaded!

var doctorStore = new Ext.data.Store({
        // load using HTTP
        url: 'test.xml',
        autoLoad:true,
        // the return will be XML, so lets set up a reader
        reader: new Ext.data.XmlReader({
          record: 'people'
          }, [
          {name: "title", mapping:"@title"}, 
          {name: "name", mapping:"@name"}, 
          {name: "city", mapping:"@city"},
          {name: "country", mapping:"@country"},
          ]),
          listeners:{
        load :function(){
            grid.getSelectionModel().selectFirstRow();
        }
          }
    });

That ist, how my XML looks like:

<list>
<people title='Dr.' name='Walter' city='Berlin' country='Germany'/>
<people title='Dr.' name='Simon' city='Frankfurt' country='Germany'/>
<people title='Dr.' name='Chris' city='Freiburg' country='Germany'/>
<people title='Dr.' name='Jens' city='Berlin' country='Germany'/>
</liste

So, can someone help me pls?

I recognized that I do not use ext 2.x - I use ext 3.x!

You could use:

record: 'people[city=Berlin]'
