go to help-> debug window -> console
Enter:
walletpassphrase "your walletpassphrase here" 60, to unlock the wallet if its encrypted.
dumpwallet "filename", will crate a plain text file in same directory where your wallet .dat file is form which you can get your xprv.
walletlock, to lock your wallet
Don't forger to erase the file after you get the info. Also if u change your wallet password the xpri will change.
Just one correction. dumpwallet "filepath+filename" and after that It will not automatically create text file but You can go to that file -> properties and then change the extension and open it with notepad. Thanks again – DOLLY PATWA – 2017-07-10T07:08:45.547
