关于prxchange()的一个问题

shiyiming

data a;
input x $60. ;
x2=prxchange('s/([\d+]):(\w+\d*\w*):([^:])/$2/',-1,x);
cards;

;
run;
我想得到被‘：’间隔开的string，比如第二个string: etl5dvh. 但如果用prxchange好像就不行，清大家帮忙看一下.
谢谢！

谢谢Ferry.
但我想得到被：间隔的每个string,比如第二个、第三个等，不仅是第二个。
using prx functions(e.g. prxchange()) instead of scan().
