Well, it simply seems like your interpretation of the words:"I want to 
extract only the "ed" string which located only at the end of the 
words", (admittedly not  perfectly clear) was and remains different 
from mine.  After all, the OP did write "at the end of the words". And 
I can't see what makes you feel he wanted just one character before the 
"ed"?
