How to process php file on tree child click event?

Question

I have created a tree panel in the Viewport and also placed a toolbar with some menu items in the north region of Viewport.

This is how it works:

1. I select File -> Open, then I get an i.e. an XML file
2. Now this "somefile.xml" will dynamically be added to the tree

I want to do the following on treeChileNodeClick:

1. Once I dblclick on somefile.xml, I want to be able to call a php file which does something with the xml file and returns the results
2. How can I run that php script?
3. How can I retrieve the returned values of that php script?

Thanks for any tip/solution.

I found out from Sencha website how to do it. Here is for people that are wandering.

Ext.Ajax.request({
    url: "test.php?id=something",
    method: "GET",
    success: function(response) {
        Ext.get("result").update(response.responseText);
    }
});

If anything needs to be added, please feel free to add.
