Construct a "Parser" instant from the original bytes

Hi, I am a freshman in htmlparser area.

My problem is:
How can I construct a "Parser" instant from the original bytes?
I have to construct a new "Parser" in this way because the original
bytes is already read from a file to the memory.


For example:
File f = new File("/home/test.html");
bytes[] b = bufferstreamreadfrom(f);
Parser p = new Parser(p);                    // how can i construct ?



Thanks for any suggestion :-)

Best Wishes,

-LIn
