HI, I am trying to construct a regEx pattern to match a UK tax code.
The pattern i have created is
"^(/BR{1}/|/D0{1}/|/NT{1}/)|^(([Kk]{1}[1-9]{1}[0-9]{2,3})|([1-9]{1}[0-9]{2,3}[LPTYlpty]{1}))"
I thought this would match the codes as BR or D0 or NT or K followed by 3 or 4 digits or 3 or 4 digits followed by L P T or Y.
However it does not work. I am quite new to regex and would be most greatful for any help.
thanks
