Excluding text in Perl

rigel_kent · 05-23-2006, 05:56 AM

Good morning,

I have a variable, $data, wich contains text (with lines, paragraphs, etc.).

How can I exclude a portion of the text beggining with some words and ending at another?

I've triesd:

Code:

$data =~ s/First words(.*|\r|\n)last words//gmi;

but it doesn't work.

Any ideas?

Regards,

well i'd suggest takign the two parts either side and joining them together afterwards.

$data =~ /^(.*)start.*end(.*)$/;
echo $1 . $2;

should work ok save for my probable syntax errors.

try

Code:

$data =~ s/First words.*?last words//gsi;

(I guess it's the /s-modifier you were looking for, and note the non-greedy *?)

Doesn't work...it should.
