i am having a lot of parameters defined in the lexer , whose input
accepts values .
but one among the parameters should accept a string which may
contain " alpha numeric characters along with a single white space in
the input string which may come at any place in the string ( for eg
in first , middle or last )"
the parameter should accept the value only if it satisfies the
above mentioned conditions otherwise it should throw an exception as
" invalid value for the parameter x ".
i have tried hidden token stream also .but it throws errors.
if anybody knows the solution let me know.
