Hi, 

I have tried to parse the following site and create a DOM tree:

http://www.in.gr/

with just the following settings:
tidy.setMakeClean(true);
tidy.setXmlTags(false);
tidy.setBreakBeforeBR(true);

and I get the following message:

The same message java.lang.NullPointerException appeared after parsing
other sites too.
Is there anyway to avoid it in general (and not only to catch it)? 
Should I change any setting? 

And a second question that I would be grateful if someone could help:
How can I redirect the output of JTidy to save it for example in a
StringBuffer?
Is there any particular I/O stream that I can use?

Thank you very much 
Nikos
