NAME

       tv_extractinfo_en - read English-language listings and extract info from programme descriptions.

SYNOPSIS

       tv_extractinfo_en [--help] [--output FILE] [FILE...]

DESCRIPTION

       Read XMLTV data and attempt to extract information from English-language programme descriptions, putting it into machine-readable form.
       For example the human-readable text '(repeat)' in a programme description might be replaced by the XML element <previously-shown>.

       --output FILE write to FILE rather than standard output

       This tool also attempts to split multipart programmes into their constituents, by looking for a description that seems to contain lots of
       times and titles.  But this depends on the description following one particular style and is useful only for some listings sources
       (Ananova).

       If some text is marked with the 'lang' attribute as being some language other than English ('en'), it is ignored.

SEE ALSO

       xmltv(5).

BUGS

       Trying to parse human-readable text is always error-prone, more so with the simple regexp-based approach used here.  But because TV listing
       descriptions usually conform to one of a few set styles, tv_extractinfo_en does reasonably well.  It is fairly conservative, trying to
       avoid false positives (extracting 'information' which isn't really there) even though this means some false negatives (failing to extract
       information and leaving it in the human-readable text).

       However, the leftover bits of text after extracting information may not form a meaningful English sentence, or the punctuation may be
       wrong.

       On the two listings sources currently supported by the XMLTV package, this program does a reasonably good job.  But it has not been tested
       with every source of anglophone TV listings.
