Hi, I've got a blood text file (as a string, column named TXT) in which I need to extract just the measure units the text I've got, i.e.. "K/UL","M/UL","%",etc. from the following: WBC 4.27-11.40 k/uL 3.64 (L)
RBC 3.90-5.03 m/uL 4.30
Hemoglobin 10.6-13.4 g/dL 13.0
Hematocrit 32.2-39.8 % 36.1
MCV 74.4-87.6 fL 84.0
MCH 24.8-29.5 pG 30.2 (H) I wrote this code : data ds;
set data;
retain re_units;
if _N_=1 then do;re_units = prxparse("~\d+-\d[\d.]*\s*\K\S+~s");end;
if missing(re_units) then do; putlog "INVALID REGEX" ;end;
do i=1 to 10;
if prxmatch(re_units, TXT) then do; units = prxposn(re_units,i,TXT);end;
output;
end;
run; Which always yielding "INVALID REGEX" at the log. But, while using RegEx simulator it yields no problem - see this. I don't know why this is happening.
