Caveat: Please do not offer split as my solution, this is geared more as a regular expression issue...

Let's use CSV as an example..

my $foo = "foo,bar,moo,cow";
$foo =~ /(?:([^,]+),)+/;
[download]

The above will only set $1 to "moo".. $2,$3,$4 are all null, $' is "cow", and $& is "foo,bar,moo"

I thought maybe the @- or @+ arrays might contain all of the matches, but to no avail...

What is strange is..

my $mystr = "foo,bar,moo,cow";
my @values = $mystr =~ m/(\w+)\,?/g;
[download]

@values will have all the matches I wanted.. But again, $1 will be set, and $2, $3, $4 will all be null.. Are capturing parentheses locked to $1 if matched multiple times? Is there any way around this? (without using split?)

Advance <- Thanks

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.
