I\'m wri开发者_开发问答ting some Extended Backus–Naur Form grammars for document parsing. There are lots of excellent guides for the syntax of these definitions, but very little online about how to d
I\'m using http://pyparsing.wikispaces.com/file/view/ebnf.py to convert my ebnf definition. ebnf def looks like this:
Is it possible to automatically convert ABNF into XML? In parti开发者_Python百科cular, I need to convert speech recognition grammars written in ABNF into XML. Thanks.Are you aware of http://www.w3.org
Docbook 5 apparently supports EBNF. But it doesn\'t output a railroad diagram. I开发者_C百科s it possible to make it output a railroad diagram (AKA syntax diagram)? The DocBook schema includes XML ele
Here\'s what I\'m trying: foreach_in.Rule = ToTerm(\"foreach\") + \"(\" + VARIABLE + \"in\" + list_obj + \")\";
I wrote down the following statement in an ANTLR grammar: loopStatement : \'loop\'(statement|exit)* \'end\' \'loop\' \';\'
This is a question both specific to the parboiled parser framework, and to BNF/PEG in general. Let\'s say I have the fairly simple regular expression
Have this EBNF grammar < calculation>-><expr> = <expr> -> <term>(+ | -) <expr>
