Hello,
I have this grammar file:
grammar VCard;
@members {
public static void main(String[] args) throws Exception {
VCardLexer lex = new VCardLexer(new ANTLRFileStream(args[0]));
CommonTokenStream tokens = new CommonTokenStream(lex);
VCardParser parser = new VCardParser(tokens);
try {
parser.line();
} catch (RecognitionException e) {
e.printStackTrace();
}
}
}
line
: property=TOKEN subtoken=SUBTOKEN* DPOINT attribute=TOKEN
{
System.out.println ("Property: " + $property.text);
System.out.println ("Attribute: " + $attribute.text);
System.out.println ("Subtoken: " + $subtoken.text);
}
;
TOKEN
: (ALPHA | DIGIT)+
;
SUBTOKEN
: SEMI TOKEN
;
WS
: ('\n' | ' ' | '\t')* {$channel=HIDDEN;}
;
fragment DIGIT
: '0'..'9'
;
fragment ALPHA
: 'a'..'z' | 'A'..'Z'
;
DPOINT
: ':'
;
SEMI
: ';'
;
And this input:
a;b;c;2:3a3bcde
This is the output:
Property: a
Attribute: 3a3bcde
Subtoken: ;2
What I like to get is:
Property: a
Subtoken: b
Subtoken: c
Subtoken: 2
Attribute: 3a3bcde
I couldn't find in the docs how to match multiple tokens that I get
from a * or + parser.
A second question is how to not include the ';' in the match.
I tried it for some time now, but I find no way. Could someone give me
an hint.
regards
Andreas
