Re: (tye)Re: Matching inconsistency in for loop

Thanks very much. That definitely helps me understand that. I've fixed the code so that I don't have to redefine the variable.
The next thing I'm having difficulty with is figuring out how to match what's inbetween the questions.
I'm trying to get

$answer =~ /$questions[$i](.*)$questions[$j]/;
print qq(The answer is $1);
[download]

or some variation of that to work(/g, /gm, etc.), but I'm not having any luck. Would somebody be able to explain how I could get the answers out of the question set?
Thanks, Rich

`if( $answer =~ /\Q$questions[$i]\E(.*?)\Q$questions[$j]\E/s ) { print qq(The answer is $1\n); }` [download] /m controls whether ^ and $ can match around newlines in the middle of the string. You want /s which controls whether . can match newlines. - tye (but my friends call me "Tye")	[reply] [d/l]

You sir, are truly a saint. I've been tearing my hair out over that for some time. I've obviously got some learning to do when it comes to regular expressions. This problem is work related, but what I plan on doing is to reformat the code and set up a Snippet on extracting questions and answers from text. Thanks.
