hi
thanks.
I know it can be done without regexp, but its just for learning
purpose, i want to use regexp
eg
someword 123456789123456789 #this is a line of a file. 'someword' is a
word before the digits
I need to get the digits into groups of 3 based on whether i found
'someword'.
so i use  this pattern :
"someword\s+(\d{3})"
but this will on give me the first 3.  I need to group them all.
hope i explain it clearly.
