\W is a negation of \w but is still including \n

I negated both with [^\w\n]

That's the result you wanted? Can't really comment on the rest, looks weird to me.

#!/usr/bin/env perl use strict; use warnings; my $book = do {local $/; <DATA>}; # slurp the book # Split book into words (delimited by \b{wb}), sequences of newlines, # and sequences of anything else. while ($book =~ /( ( [^\w\n]+ ) | ( \b{wb}.+?\b{wb} ) | ( \n+ ) ) /xg) { show($1); } print "\n"; # show(): make spaces and newlines visible sub show { my $str = shift; $str =~ tr/\n/$/; $str =~ tr/ /_/; print "{$str}\n"; } __DATA__ --First paragraph-- Second one's followed by only one newline.

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.
