Using Parse::RecDescent

• The Perl part of using Parse::RecDescent is very simple.
• Basically, one has two strings. One string containing the grammar, another string containing the text that has to be parsed.
• First, create a parser:
  
  my $parser = Parse::RecDescent -> new ($grammar) or die;
  
  
• Then, parse the text given a certain startrule:
  
  my $result = $parser -> startrule ($text);
