[Vala] parsing RSS file in Vala

[Pavol Klačanský]

Hi, I have written just simple Vala program, which should print out name
of root element

Without this line it works "<?xml version="1.0"
encoding="windows-1250"?>" (first line in RSS xml files)

OUTPUT

$ ./xml_parser rss.xml encoding error : input conversion failed due to
input error, bytes 0x88 0x6F 0x76 0x61
encoding error : input conversion failed due to input error, bytes 0x88

    Parser.init ();

    
    var sample = new xml_parser ();
    // Parse the file listed in the first passed argument
    sample.parse_file (args[1]);

    // Do the parser cleanup to free the used memory
    Parser.cleanup ();

    return 0;
