Hello all,
I want extract the number after the last '/', how to do it?
below is the character, I want '9245',:
'Kwstala/416544/95ewS661204/9245'
Thank you!
Use SCAN() function with a index of -1.
want = scan('Kwstala/416544/95ewS661204/9245',-1,'/');
Thank you!
and another question,how to get the location of the last '/'?
Thanks!
You can use those PRX functions to get the target striong as well the postion:
data test;
want_scan = scan('Kwstala/416544/95ewS661204/9245',-1,'/');
ptn=prxparse('/(?<=\/)\d+$/');
pos=prxmatch(ptn,'Kwstala/416544/95ewS661204/9245');
want_prx=prxchange('s/(\S+)\/(\d+$)/\2/',-1,'Kwstala/416544/95ewS661204/9245');
run;
data _null_;
want_scan ='Kwstala/416544/95ewS661204/9245';
pos=findc(want_scan,'/','b');
put pos= ;
run;
