++ Yes, that works and is less complicated still. :-)

It wouldn't have occurred to me not to use a capture group. I checked the online docs and found in perlretut - Using regular expressions in Perl - Global matching (after following links from perlre):

In list context, //g returns a list of matched groupings, or if there are no groupings, a list of matches to the whole regexp. [my emphasis]

That seemed new to me (those links are for 5.16.2), so I checked back to the earliest online perldoc version (5.8.8) and, while in a different manpage (http://perldoc.perl.org/5.8.8/perlop.html#Regexp-Quote-Like-Operators) with different wording, that behaviour was current back then:

In list context, it returns a list of the substrings matched by any capturing parentheses in the regular expression. If there are no parentheses, it returns a list of all the matched strings, as if there were parentheses around the whole pattern. [my emphasis, again]

I've learned something new. Thankyou.

Title:
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 or How to display code and escape characters are good places to start.
