Extract text from a multiline string using Perl

Question

I have a string that covers several lines. I need to extract the text between two strings. For example:

Start Here Some example
text covering a few
lines. En         


        

Answer 1

Use the /s regex modifier to treat the string as a single line:

/s Treat string as single line. That is, change "." to match any character whatsoever, even a newline, which normally it would not match.

  $string =~ /(Start Here.*)End Here/s;
  print $1;

This will capture up to the last End Here, in case it appears more than once in your text.

If this is not what you want, then you can use:

  $string =~ /(Start Here.*?)End Here/s;
  print $1;

This will stop matching at the very first occurrence of End Here.
