Is it possible to extract specific info from a bitcoin rpc call

Example and im going to use an altcoin as its easier but I guess the same applies to BTC

I use the command "Swingd getmininginfo" and the out put is this:

Code:
"Blocks" : 405319,
    "Current Block Size" : 1000,
    "Current Block Tx" : 0,
    "Difficulty" : {
        "Proof of Work" : 2614987.07498234,
        "Proof of Stake" : 0.03581758,
        "Search Interval" : 1
    },
    "Block Value" : 159500000,
    "Net MH/s" : 72930415.36696009,
    "Net Stake Weight" : 922198.70837217,
    "Errors" : "",
    "Pooled Tx" : 0,
    "Stake Weight" : {
        "Minimum" : 61,
        "Maximum" : 0,
        "Combined" : 61
    },
    "Stake Interest" : 9000000,
    "Testnet" : false


Is it possible to adjust the command "getmininginfo" to display for example Net MH/s or Net Stake Weight instead of all the output ?

I am building a webpage that I want to show weight and net hash but not the rest of the out put

Thanks

You can use a JSON library to parse the output (which is in JSON format) and then pull out the parts that you want. Or you can directly modify the source code for the RPC to only give you the info that you want.

Thanks for the speedy reply.

JSON is out of the question for this project and i have tried various commands such as getnethash etc etc but none work

All you need to do is parsing  json output, and do simple calculation
