Parser runs nicely: how to apply some separators of the table

hello dear all - hello all freaks of this great community,

 

 

one question regarding a parser... note - it is a perl-parser, but believe me: i need some help  with that. And i guess that here many many experts know the perl-bits... so well that this is no problem here....

 

Here we go! is there any chance to catch some seperators within the that seperate the table...  The paser script runs allready nicely. Note - i want to store the data into a MySQL database. So it would be great to have some seperators - (commas, tabs or somewhat else - a tab seperated values or comma seperated values

are handy formats to work with...

 

here the data out of the following site:  http://192.68.214.70/km/asps/schulsuche.asp?q=a&a=20

Well i need to have those lines divided into at least three columns - take the first record.

name: Volksschule Abenberg (Grundschule)

street: Güssübelstr. 2

postal-code and town: 91183  Abenberg

fax and telephone: 09178/215 09178/905060

type of school: Volksschulen

website: home.t-online.de/home/vs-abenberg

 

Or even better - i have divided the postal-code and town into two seperate columns!?

Question: is this possible?

 

By the way: see the first record: (here i only show the names of the school)

 

1 0401 Mädchenrealschule Marienburg, Abenberg,

6 3074 Private Berufsschule zur sonderpäd. Förderung, Förderschwerpunkt Lernen, Abensberg

 

Note, those have some commas inside the name; does this make it difficult to create a parser that creates csv-fomate?

 

Any idea how to do this in Perl... If possible it would be just great!!

 

many many thx for a hint regarding this little issue - besides this all is great and fascinating!

                $total_records = $6;
                print "Total records to process is $total_records\n";
                }
             }
             close FH;

          for my $row ( $table->rows ) {
             cleanup(@$row);
             print OUTFILE "@$row\n";
          }
          $| = 1; 
          print "Processed records $range to $counter";
          print "\r";
          $counter = $counter + 50;
          $range = $range + 50;
          $te = HTML::TableExtract->new;
       }
    }

    sub cleanup() {
       for ( @_ ) {
          s/s+/ /g;
       }
    }

    sub workDir() {
    # Use home directory to process data
    chdir or die "$!";
    if ( ! -d $processdir ) {
       mkdir ("$ENV{HOME}/$processdir", 0755) or die "Cannot make directory $processdir: $!";
       }
    }
