No, but most of them had a copyright of their name, i think...

Before I used a text form of a grammer like this
%token Identifier [A-Za-z][A-Za-z0-9_]*;
%token Number [+\-]? ( ([0-9]+ \.[0-9]*)?(E[+\-]?[0-9]+)? |
[0-9]*\.[0-9]+(E[+\-]?[0-9]+)? );
%token String \" ( [^\\\"] | \\[^u] |
\\u[0-9a-fA-F][0-9a-fA-F][0-9a-fA-F][0-9a-fA-F] )* \";
%token Boolean TRUE|FALSE;
%comment #([^\n]*);
%whitespace [\n\r\t\u0020]+;
%start File;
%%
Tupel : (String | Number) (String | Number)+;
Field : "[" (String | Number | Tupel) ("," (String | Number |
Tupel) )* "]";
Declaration : Identifier (String | Number | Tupel | Field);
Node : Identifier "{" (Node | Declaration)* "}";
File : (Node | Declaration)+;

This I have already done ;-)

Whats about
<token tsymbol="eol">
<alt>
<concat>
<string content="\r"\><string minOccurs="0" content="\n"\>
</concat>
<string content="\n"\>
</alt>
</token>

I think yes, with a little work, you could do something like
syntaxhighlighting.

The (fragment) text parser generator produce a SAX stream, which could be
transformed in a pipeline.
