I have a string variable containing licence plates, names and dates separated by / . As in 122000200106_Cheyrmen, Murauwatpur Panchayat Pacs-02/11 where 11 is 2011, in 121900200198_Shiv Nath Prasad Sah-72/2007 2007 is 2007, and in 121500100430_Dinesh Poddar-02/93 93 is 1993. How can I extract the year in YYYY format? Any suggestions would help, thanks
