See "Multiple Input Buffer" in flex help:
http://flex.sourceforge.net/manual/Multiple-Input-Buffers.html#Multiple-Input-Buffers
in this way you can parse a string:

       #include "y.tab.h"
       //declaration
       typedef struct yy_buffer_state *YY_BUFFER_STATE;
       YY_BUFFER_STATE yy_scan_string(const char*str);
       void yy_switch_to_buffer(YY_BUFFER_STATE new_buffer);

       //code
       YY_BUFFER_STATE b=yy_scan_string(stringToParse);
       yy_switch_to_buffer(b);
       yyparse();
