After Decryption :

Now i want to extract the contents of this DE

Not sure what you mean, but I hope that was your own card (or a test plastic) with a future expiry data and not someone else's live Jyske Bank card;  if it is then please do let them know to request a replacement and perhaps report this one pan, expiry and perhaps cvv (depending on method of capture used at the terminal) compromised.

Any Help will be appreciated.

You would need to ask the Issue for their layout - if breaking down the discretionary data in that track is your goal.

If you want to get the data, then you have done do by treating the packager to gather the encrypted form and then access it via the encryption key/method. just as you have above.
