[antlr-interest] handling /// comments

[ajk .]

Hi

I was wondering if somebody has an idea how to solve the following problem.
Lets see if I can describe the issue in a proper way.

We have a translator that translates a scripting language to C#.

We now need to support ///<summary>.. in C#

By adding the /// in the scripting language we were hoping just to move this
over to C#:

example

/// <summary>
/// some function
/// </summary>
myfunction returns int
begin
   bla();
end

->

C#
 /// <summary>
/// some function
/// </summary>
int myfunction()
{
  bla();
}

So far so good, I would associate the comments to the following function
which is a node in the AST, simple to do a parser rule for this.

But in C# (as well as the scripting language) you can write comments
anywhere in the code in whatever form you want e.g.

/// hello

or

///////////////////////////////////////////
//// this freestanding comment
////////////////////////////////////////////

How do you filter away these things? How do I write a parser rule that
allows comments anywhere in the original code but only move the relevant
ones? i.e. the ones associated with certain elements like functions,
variable declarations etc.

TIA
Anders.
