Hi All ,, Good morning.
I m very new to ANTLR , I m facing a below problme like the second rule is
getting matched with the first rule and its not able to be parsed.
This is my grammar
grammar tel;
TEL : T E L COLON ;
COLON : ':';
fragment T : ('t'|'T');
fragment E : ('e'|'E');
fragment L : ('l'|'L');
URI : TEL (parameter)*;
parameter : pname '=' pvalue ;
pname:ALPHA;
pvalue=ALPHA;
Now when I pass the value as "tel:airtel=provider" then the parser
validation fails,
The exception got in " Mismatch character "=" expected ";" " , this is like
for the input "tel:airtel=provider" the stream "tel" is taken and validated
for the rule "TEL"
But its expected to alphabets.
Pls give ur suggestion on this.
Thanx a lot for reading this.
