Re: [Htmlparser-user] Malformed Input Exception

[Derrick O. <Der...@ro...>]

If I recall correctly, implementing this feature would require deferring 
not only the connect but also the determination of the character set 
(from the header returned by the connect) and creation of the reader 
(because it needs the character set, and an input stream) until 
elements() is called.  elements() would need to check for a null reader 
and do the work. Then getReader() and getEncoding() would also have to 
handle a null reader or null character_set too. Are there other subtleties?

Maybe tricky, but probably do-able.  I think all the constructors have 
test cases.

But then, all that's really being saved is the user coding:

    Parser parser = new Parser ("http://yadda");
    URL url = parser.getConnection ();
    ...process the url as appropriate
    ... parser.elements ()

instead of:

    URL url = new URL ("http://yadda");
    url.openConnection ();
    ...process the url as appropriate
    Parser parser = new Parser (url);
    ... parser.elements ()

So it's probably not really worth the convoluted coding, unless I'm 
missing something in the use-case.
