XMLTV::Augment - Man Page
Augment XMLTV listings files with automatic and user-defined rules.
Description
Augment an XMLTV 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 if necessary).
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 = UTF-8)
stats => whether to print the audit stats in the log (values = 0,1) (default = 1)
log => filename of output 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 if necessary
$augment->end();Note: you are responsible for reading/writing to the XMLTV .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. So for example "News%%" will match "News", "News and Weather", "Newsnight", etc. But be careful; "%%News%%" will also match "John Craven's Newsround", "Eurosport News", "Election Newsroom Live", "Have I Got News For You", "Scuzz Meets Jason Newsted", etc.
