Unable to querry Description field of Service now

Hi All,

I want to query Description field of Service Now task.

Description field has format like this

Server : value xyz

patching cycle : value xyz

reboot type : value xyz

jjjjjjjjj : value

jjjjjkk : value

jjdjjd : value

For every task, description has same format. I want to extract value of server, patching cycle, reboot type . Rest I don’t need.

Based on those values i will ask my bot to perform action.

Any suggestion by which I can achieve this.
