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

I downvoted your post since you obviously did not read the links biohisham gave you.

Had you done so, you would surely have formatted your second post with <p></p> and <code></code> tags:

thanx so much for ur advice... actually am a new in perl monk...
actually i want to make a database of mp3 songs. so after retrieving the tag info of each song..i got a output like :

Artist: Rock Title: Fusion Album: Fusion Year: 2002 Genre: Other Artist: MelB Title: who am i: Album: donny Year: 2004 Genre: Other Artist: bon jo Title: i can stay Album : Armyman Year: 2009 Genre: Other Artist: Pearl Title: Last Album: Jam Year: 1983 Genre: Other

now i want my database to be like :

Artist Title Album Year Genre ------ ----- ----- ----- ----- Rock bbb hhh 2000 POP MelB Hum por 2003 other bon jo Armyman 209 others

etc.

#!/usr/bin/perl use warnings; use strict; my %hasharray; open (my $fh, "<", "C:/songdata1.txt") or die "can't open the file"; while (<$fh>){ my ($header,$info) = split /:/; }

I dont know how to proceed futher.
plz help me out.

Now, to help you out:

  • make sure your records are separated with an empty line
  • read the input file in paragraph mode (switch -p00, see perlrun)
  • split the resulting records at "\n"(newline) into an array
  • iterate over this array, split each element into ($header,$info)
  • populate a hash (see perldata) with $header as key, $info as value
  • done iterating over the array, output the records (see perlform for formatted text output)

In reply to Re^3: converting rows into column by shmem
in thread converting rows into column by changma_ha

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.
