Foreach regex

[jriggs420]

Hello again,

I have the following loop:

     20 my $line;
     21 foreach $line (@_){  do sth ;  }

Simple enough, but I can't figure out how to only set $line equal to strings that contain no text (blank whatever). I have tried the following conditions in various places within the loop with no success. Any ideas?

!/^\s*$/ and !~/^\s*$/
@_ = grep { $_ !/^\s*$/} @_;
TIA

Joe

well, for edification, you're matching lines that don't contain only spaces because you are using the negation operator "!", just remove the ! and it should work.
