( #3333=superdoc: print w/replies, xml ) Need Help??
You are overwriting your hash every time through the while loop. Move the declaration of the hash outside of the loop:
my $csv = Text::CSV_XS->new(); open (FILE, "<", "$tickdir/$file") or die "Can't open CSV File:$! +\n"; my %HOH; while (<FILE>) { $csv->parse($_); my @columns = $csv->fields(); my $key = str2time($columns[1].' '.$columns[2]); my (@prices, @volumes) = (); $HOH{$key}{"name"} = $columns[0]; push(@{$HOH{$key}{"price"}}, $columns[3]); push(@{$HOH{$key}{"volumes"}}, $columns[4]); print Dumper(\%HOH); } close FILE;

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.
