Linkage with C++ programs & Re: Re: Why some xml files are not parsed ?

Hi,

Thanks a lot for replying my newbie n basic question. :) . I am not very
familiar with scheme sysntax and programs, that is why i posted that
doubt.
The following code also worked well, to give the output in console. This
is frm the example file given in the ssax library for bigloo users.
(module convert
  (main main))

(define (main argv)

  (if (not (= 2 (length argv)))
      (exit 4))     ; at least one argument, besides argv[0], is expected
  (pp
   (call-with-input-file (cadr argv)
     (lambda (port) (ssax:xml->sxml port '()))))
)


I have another doubt - is is possible to call this code snippet ( i.e
converitng xml to sxml ) from a c / c++ programs ? Plz give some simple
example to link ssax lib and other programming languages. What i need is a
set of s-expressions as an input to a c++ program. Can i use SSAX pacakge
to feed the input data ?

Thank you again

Shinni
