( #3333=superdoc: print w/replies, xml ) Need Help??

Following your approach, I came with the following code that creates one array with all the strings that result from the concatenation of all the columns. Note that I'm not taking into account eventual memory problems that may arise from the amount of columns/lines your csv may have.

use strict; use warnings; use Data::Dumper; my @parsed = (); while (<DATA>) { my $in = $_; chomp($in); my @line = split(/,/, $in); for my $i(0..$#line) { $parsed[$i] .= $line[$i].'|'; } } map {chop} @parsed; print Dumper(\@parsed); __DATA__ 123,"text",66,"more text" 124,"text1",67,"more text1" 125,"text2",68,"more text2"

outputs

$VAR1 = [ '123|124|125', '"text"|"text1"|"text2"', '66|67|68', '"more text"|"more text1"|"more text2"' ];

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.
