NAME

XMLTV::Augment - Augment XMLTV listings files with automatic and user-defined rules.

DESCRIPTION

Augment an xml file by applying corrections (``fixups'') to programmes matching defined criteria (``rules'').

Two types of rules are actioned: (i) automatic, (ii) user-defined.

Automatic rules use pre-programmed input and output to modify the input programmes. E.g. removing a ``title'' where it is repeated in a ``sub-title'' (e.g. ``Horizon'' / ``Horizon: Star Wars''), or trying to identify and extract series/episode numbers from the programme"s title, sub-title or description.

User-defined rules use the content of a ``rules'' file which allows programmes matching certain user-defined criteria to be corrected/enhanced with the user data supplied (e.g. adding/changing categories for all episodes of ``Horizon'', or fixing misspellings in titles, etc.)

By setting appropriate options in the ``config'' file, the ``rules'' file can be automatically downloaded using XMLTV::Supplement.

EXPORTED FUNCTIONS

setEncoding

Set the assumed encoding of the rules file.

inputChannel

Store each channel found in the input programmes file for later processing by ``stats''.

augmentProgramme

Augment a programme using (i) pre-determined rules and (ii) user-defined rules. Which rules are processed is determined by the options set in the ``config'' file.

printInfo

Print the lists of actions taken and suggestions for further fixups.

end

Do any final processing before exit (e.g. close the log file).

INSTANTIATION

    new XMLTV::Augment( { ...parameters...} );

Possible parameters:
      rule       => filename of file containing fixup rules (if omitted then no user-defined rules will be actioned) (overrides auto-fetch Supplement if that is defined; see sample options file)
      config     => filename of config file to read (if omitted then no config file will be used)
      encoding   => assumed encoding of the rules file (default = 

)
      stats      => whether to print the audit stats in the log (values = 0,1) (default = 1)
      log        => filename of output log (default = augment.log)
      debug      => debug level (values 0-10) (default = no debug)
                        note debug level > 3 is not likely to be of much use unless you are developing code

TYPICAL USAGE

 1) Create the XMLTV::Augment object
 2) Pass each channel to inputChannel()
 3) Pass each programme to augmentProgramme()
 4) Tidy up using printInfo() & end()

        #instantiate the object
        my $augment = new XMLTV::Augment(
                  "rule"       => "myrules.txt",
                  "config"     => "myconfig.txt",
                  "log"        => "augment.log",
                  );
        die "failed to create XMLTV::Augment object" if !$augment;

        for each channel... {
          # store the channel details
          $augment->inputChannel( $ch );
        }

        for each programme... {
          # augmentProgramme will now do any requested processing of the input xml
          $prog = $augment->augmentProgramme( $prog );
        }

        # log the stats
        $augment->printInfo();

        # close the log file
        $augment->end();

Note: you are responsible for reading/writing to the

.xml file; the package will not do that for you.

You can specify a wildcard with the title by using %% which represents any number of characters.

  rule: 15|cnbc.com~News~Business
  in : "Investing in India" category ""
  out: "Investing in India" category "News" + "Business"

EVERY

programme broadcast on that channel. This may not be what you always want (e.g. Teleshopping isn't really ``music'' even if it is on

MTV

!)
