recover yyparse after yyaccept - c

Question

Friends, I am parsing a bibtex file, having multiple bibtex entry within a file, e.g.
#Book{a1,
Title="ASR",
Publisher="oxf",
Author = {a {\"m}ook, Rudra Banerjee},
Year="2010",
Address="UK",
Edition="1",
}
#Article{a2,
Author="Rudra Banerjee",
Title="Fe{\"Ni}Mo",
Publisher="P{\"R}B",
Number="12",
Pages="36690",
Year="2011",
Address="UK",
Edition="1",
}
Now, I want yyparse to return after each entry, hence, my parser is:
%union
{
char *sval;
};
%token <sval> VALUE
%token <sval> KEY
%token OBRACE
%token EBRACE
%token QUOTE
%token SEMICOLON
%start Input
%%
Input:
/* empty */
| Input Entry ; /* input is zero or more entires */
Entry:
'#' KEY '{' KEY ','{
g_hash_table_insert(table, g_strdup("TYPE"), g_strdup($2));
g_hash_table_insert(table, g_strdup("ID"), g_strdup($4));
g_printf("%s:%s\n","KEY=>",g_hash_table_lookup(table,"TYPE"));
// g_printf("%s: %s\n", $2, $4);
}
KeyVals '}'
{YYACCEPT;}
;
KeyVals:
/* empty */
| KeyVals KeyVal ; /* zero or more keyvals */
KeyVal:
KEY '=' VALUE ',' { g_hash_table_insert(table, g_strdup($1), g_strdup($3));
// g_printf("%s: %s\n", $1, $3);
g_printf("%s:%s\n",$1,g_hash_table_lookup(table,$1));
};
%%
and in main routine, it is called as:
do{
yyparse();
}
The problem is, it is parsed correctly, but only the first entry; i.e. it is not recovering from the YYACCEPT.
How I can make the code recall the yyparse again after yyaccept?
This is almost same question as How do I convince Bison to parse part of a file? But I have failed to solve my problem.

You should enable the %debug traces to check what is going on. Also, given what you are trying to do, you should probably give a try to push parsers instead (http://www.gnu.org/software/bison/manual/html_node/Push-Decl.html).
