Re: Parse

[tshabet]

These guys are absolutely right. To take the example further, lets say you have this math expression:

Z=(A-(C*K))

when you parse this, it becomes

                              =
                           /      \
                         -         Z
                       /   \
                     A      *
                           / \
                          C   K   

So parsing something really is about breaking it down into its individual chunks and pieces. For instance, a parser might break your c++ program into functions, or your word into letters. If you have a whole made of parts, the parser looks at those parts. Make sense? Check out the definitions linked above, they're probably better at explaining it than I am. Hope that helped a little. PS The above is a "parse tree", certainly not the only way to parse or represent a parse. Just so you know.

Alternate parse representation of  $Z=($A-($C*$K)) care of ppi_dumper :) notice how it labels each part :)

PPI::Document
  PPI::Statement
    PPI::Token::Symbol          '$Z'
    PPI::Token::Operator        '='
    PPI::Structure::List        ( ... )
      PPI::Statement::Expression
        PPI::Token::Symbol      '$A'
        PPI::Token::Operator    '-'
        PPI::Structure::List    ( ... )
          PPI::Statement::Expression
            PPI::Token::Symbol          '$C'
            PPI::Token::Operator        '*'
            PPI::Token::Symbol          '$K'

Parsing information is a management attribute, that defines the ability to select the salient points from a large amount of submitted information. The ability enables the discovery of the needle in the haystack.
