Regular Expressions

Split

• The "split" construct takes a supplied scalar string and breaks it into an array of tokens (still scalar strings).
• The "split" construct decides how to split the string based on a supplied regular expression.
• The format of "split" is as follows:
  @arrayname = split ( regexp, $scalarvar);
• Example:
  

  #!/usr/bin/perl -w
  use strict;
  
  my ($theVar, @theArray);
  
  # split unix or dos complete file path into tokens
  $theVar = 'c:\windows\sys\random\mysterious\but\critical.dll';
  @theArray = split( /[\\:\/]/, $theVar );
  print "@theArray\n";
  
  $theVar = "/etc/rc/rc.d";
  @theArray = split( /[\\:\/]/, $theVar );
  print "@theArray\n";
