hi all
i am new in lex programming,i tried to find one token (i.e. "="),then change
value of after "="
i succeed in find token one occurence in one line using follwing code
=[^\n<>"]* {
printf ("\n token value is %s\n",yytext);
printf ("\nenter new value\n ");
memset (chr,0x00,sizeof(chr));
memset (next_char,0x00,sizeof(next_char));
next_char[0] = '=';
next_char[1] = ' ';
scanf("%s",chr);
strcpy(yytext,"=");
strcat(next_char,chr);
fputs(next_char,yyout);
}
but problem if one line contain more than one occurence of "=" in same line
it change only first occurence token
so please anybody suggest best regular expression to solve this problem
