parsed
parsing

    An algorithm or program to determine the
   syntactic structure of ("to parse") a sentence or string of
   symbols in some language.  A parser normally takes as input
   a sequence of tokens output by a lexical analyser.  It may
   produce some kind of abstract syntax tree as output.  A
   parser may be produced automatically from a grammar by a
   parser generator such as yacc.

   A parser is normally part of some larger program, like a
   compiler, which takes the output of the parser and attempts
   to extract meaning from it in some way, e.g. translating it
   into another language.
