[Grammatica-users] How can I generate grammar at run-time?

[Ламер]

Hi,

Is it possible to generate grammar on the fly. I want to parse an input text
depending on the grammar_1 that will be taken at run-time. Parse this 
grammar_1, generate grammar_2
and parse the input text based on grammar_2.

e.g.
--------------------------------------------------------------------------------------------------------------------------------
 /** 
  *Grammar_1, it some language that tells to my parser in which form input text 
will be,
  * like:
  */
  <<${title}>>, ${date}, ${time}, ${tvname} /${author}/ =${duration}=
  ${text}

 /* parse this grammar_1, generate grammar_2
  * for the input like the following one:
  */

<<Evening News>>,12 november 2009, 19:30, KazakhstanTV /Name Surname/ =4,00=
Some input text,sdlfjlskdjfk

/**
 * At the end it should retrieve variables, like
 * ${title} = Evening News
 * ${date} = 12 november 2009
 * etc.
 */
--------------------------------------------------------------------------------------------------------------------------------

Thanks in advance, any help will be appreciated

P.S. Sorry for any grammatical mistakes in English ;)
