Dear all,

My rule is:
---------------------------
white ([ \t]+)

%%
{white} ;
[^ \t\n]+ {printf("Got string = %s\n",YYText());}
. ECHO;
\n ;

%%
--------------------------

My input is a file, for example test.txt
test.txt:
--------------------------
abcd123 1000
.
.
.
--------------------------

I can get first string is "abcd123".


But if test.txt's first lines are blanked (only '\n'),
for example the first 2 lines are just '\n'.
I got first string is "\n\nabcd123".

What's wrong?
How should I fix it?

Thanks for your help.

Best Reards,
cylin.

I solve it.

If a file is DOS mode,
then you must remeber to add '\r' and combine '\n' to get end of line.
