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

In that case it's fairly easy. I used Text::CSV to read the data file, but AFAIK it doesn't support ignoring comment lines. If you are certain your files are always going to be as simple as you showed, only two columns separated by | and no |s anywhere else, no quoted fields, etc., then it's also possible to parse the file manually with a regex, for example:

open my $fh, '<:encoding(UTF-8)', $filename or die "$filename: $!"; my @rows = map { /^([^|]+)\|([^|]+?)$/ or die $_; [$1,$2] } grep { /\S/ && !/^\s*#/ } <$fh>; close $fh;

And then you can use @rows instead of @$rows in my example above.

Update: Minor simplification to code.

Update 2: And soonix makes a good point that continuing to use Text::CSV is also most likely fine, since it's probably safe to assume that you don't have any actual data that starts with #.

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.
