code to extract movie name out of file name

step 1: regex filter 1: to remove all data in () and [] after extracting information like season no / episode no from it. Regular expressions used are:

  "/\[.*?\]|\(.*?\)/"
  "/s(\d{1,2})e(\d{1,3})|(\d{1,2})x(\d{1,3})/";

step 2: Now a movie name may look like:

Iron.Man.3.213.3D.18p

Replace the "." with " " or white space to get name like

Iron Man 3 213 3D 18p

Now the movie is of From

[name] [version] [year] [3D/2D] [resolution]

So now we need to parse this kind of name to get all information!

Parsing can be done using different regex filters

Regex 1: to identify movie part no like in Iron Man 3

/\b\d /i

Regex 2: to determine the year like Iron man 213 or Iron Man 2013

/\d{3,4}/i

Regex 3: to determine dimensions like Iron man 3D or Iron Man 3d

/[0-90]{1}d|[0-9]{1}D/i

Regex 4: to determine Resolution like Iron man 18p or Iron Man 1080p

/\d{1,4}p|\d{1,4}P/

And from this we can generate information like

  Filename: Iron.Man.3.213.3D.18p
  Title: Iron Man 3
  Part: 3
  Year: 213
  Resolution: 18p
  Dimension: 3D
