( #3333=superdoc: print w/replies, xml ) Need Help??
here's a (untested) solution using Text::CSV .. what modules did you try? if you show your attempts w/specific modules (maybe as separate posts), we can probably help with them..
my $data = {}; use Text::CSV; my $csv = Text::CSV->new(); open FILE, "foo.txt"; # open a file my $line = <FILE>; # get the header line $line =~ s/^#//; # strip off leading # $csv->parse($line); # parse line ... my @cols = $csv->fields(); # ... storing column name +s while(my $line = <FILE>){ # loop through rest of file $csv->parse($line); # parse line ... my @vals = $csv->fields(); # ... getting the values # my %row = map { $cols[$_] => $vals[$_] } 0 .. $#cols; # and hashi +ng up based on col names # $data->{ $row{ $cols[0] } } = \%row; # stick this hash into big + data structure. # NOTE: it's hashing on th +e first column.. # might want to change if +necessary # UPDATE: just use a hash slice: @{ $data->{ $row{ $cols[0] } } }{ @cols } = @vals; } close FILE; # close file -- all done!

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

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
