Dear all,
I want to parse the same file multiple times,
depending on the number of input arguments. The input
file name is an extern variable defined in the
grammar. Here is a segment of the main function.
// ...
if (frules.substr(frules.find('.')) == ".rules"){
ifstream infile (frules.c_str(), ios::in);
if( !infile.is_open() ){
cerr << "Error in opening the conversion rules
file" << endl;
return 1;
}
for( int i = 2; i < argc; i++ ){
xml_file = argv[i]; // a global variable
XML2OWLLexer lexer(std::cin);
XML2OWLParser parser(lexer);
LexerSharedInputState lex_state =
lexer.getInputState();
lex_state->initialize(infile, frules.c_str());
parser.getInputState()->reset();
parser.setFilename(frules);
parser.file();
// ...
The first execution of the for loop is witout any
error. During the second execution, the parse throws
the following error
cont.rules:1:1: unexpected end of file
Thanks
Mach
