Need help with Swissknife

[C. Tobini]

Hello, I'm beginner with Swissknife libraries and I need to parse a
SWISS-PROT file. I read the swissknife.sourceforge.net inline help but
I run some problems.

I would like to know how to use the SWISS::Refs library.

For example, with a $entry variable for the file path, I tried to use,
as explained :

$/="\/\/\n" ;

open (FILE, "$file_path") ;
while(<FILE>)
  {
   $entry = SWISS::Entry -> fromText($_) ;

   @REF_ARRAY = $entry -> Refs -> list ;

   ...

   }

But I can't apply RC or RX methods on the created object.

If you could say to me how to extract those fields, that yould be
great.

Thanks.
