Alternatively, if you want to find the queries, knowing the allowed query keywords (e.g. SEL, SELE, SELEC, SELECT if all are possible and any other valid SQL keywords)... this would also make the parse pretty trivial.
I'd read the whole line and see if it begins a query (however you want to do that)... then set a flag to be in a query... and look for line (could be same line) ending in semi-colon to terminate the query. Skipping lines that can't be a query.

DESCRIPTION
The grammar was started from the MySQL parsers. Here is the description from PostgreSQL:
Table: (http://www.postgresql.org/docs/view.php?version=7.3&idoc=1&file=sql-createtable.html)
CREATE [ [ LOCAL ] { TEMPORARY | TEMP } ] TABLE table_name (
{ column_name data_type [ DEFAULT default_expr ]
[ column_constraint [, ... ] ]
| table_constraint } [, ... ]
)
[ INHERITS ( parent_table [, ... ] ) ]
[ WITH OIDS | WITHOUT OIDS ]
where column_constraint is:
[ CONSTRAINT constraint_name ]
{ NOT NULL | NULL | UNIQUE | PRIMARY KEY |
CHECK (expression) |
REFERENCES reftable [ ( refcolumn ) ] [ MATCH FULL | MATCH PARTIAL ]
[ ON DELETE action ] [ ON UPDATE action ] }
[ DEFERRABLE | NOT DEFERRABLE ]
[ INITIALLY DEFERRED | INITIALLY IMMEDIATE ]
and table_constraint is:
[ CONSTRAINT constraint_name ]
{ UNIQUE ( column_name [, ... ] ) |
PRIMARY KEY ( column_name [, ... ] ) |
CHECK ( expression ) |
FOREIGN KEY ( column_name [, ... ] )
REFERENCES reftable [ ( refcolumn [, ... ] ) ]
[ MATCH FULL | MATCH PARTIAL ]
[ ON DELETE action ] [ ON UPDATE action ] }

[ USING acc_method ] ( column [ ops_name ] [, ...] )
[ WHERE predicate ]
CREATE [ UNIQUE ] INDEX index_name ON table
[ USING acc_method ] ( func_name( column [, ... ]) [ ops_name ] )
[ WHERE predicate ]
