If I understood your earlier reply correctly, the regex does match (with the alternation), but it doesn't match the way you want. That's a big difference, and what I tried to explain to you.
That's the behavior I want with regards to the rest of the records.

After looking at the updated data I think that you need two regexes for that:

use strict; use warnings; my $str = do { local $/; <DATA> }; if ($str =~ m/Remediation Report\n\n(.+?)\n/g){ print $1, $/; while ($str =~ m/\n\n(.*)\n/g){ print $1, $/; } } __DATA__ thread-index: AcjoCau17Ri90HMJR8qoukn2A1g7ng== MIME-Version: 1.0 # rest of data goes here

The output is:

Adobe Flash Player Multiple Vulnerabilities - April 2008 - IE Adobe Flash Player Multiple Vulnerabilities - April 2008 - Mozilla/Ope +ra Adobe Reader/Acrobat 8.1.2 and 7.1.0 Update - Acrobat 7.x

The trick is to use the /g-modifier on the first regex although it matches only once. That way pos $str will not be reset, and the next regex match starts where the previous left off.

Also note that ^ will anchor to the start of the string (not to the start of a line) unless the /m modifier is present.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
