Extracting a subset of attributes with JSONPath

Question

I have this JSON code:

{     "A": {         "AB": [{             "ABA": "0",             "ABB": "1",             "ABC": "2"         }]     } } 

I need to use a JSONPath expression that returns that JSON with only ABA and ABC attributes. Something like:

{     "A": {         "AB": [{             "ABA": "0",             "ABC": "2"         }]     } } 

So far I manage to extract either one or all attributes. For example

$.A.AB[*] 

or

$.A.AB[*].ABA 

Is there a way to extract only two?

Thanks

This will work using the Jayway implementation (Java):

$.A.AB[*]['ABB', 'ABA'] 

and the result for your input would be:

[    {       "ABB" : "1",       "ABA" : "0"    } ]
