how to remove the warnings in Jtidy in java

I am using Jtidy parser in java.

URL url = new URL("www.yahoo.com"); 
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
InputStream in = conn.getInputStream(); 
doc = new Tidy().parseDOM(in, null);

when I run this, "doc = new Tidy().parseDOM(in, null);" I am getting some warnings as follows:

Tidy (vers 4th August 2000) Parsing "InputStream"
line 140 column 5 - Warning: <table> lacks "summary" attribute

InputStream: Doctype given is "-//W3C//DTD XHTML 开发者_如何学C1.0 Strict//EN"
InputStream: Document content looks like HTML 4.01 Transitional

1 warnings/errors were found!

These warnings are getting displayed automatically on console. But I don't want these warnings to be displayed on my console after running

doc = new Tidy().parseDOM(in, null);

Please help me,how to do this,how to remove these warnings from console.

Looking at the Documentation I found a few methods which may do what you want.

There is setShowErrors, setQuiet and setErrout. You may want to try the following:

Tidy tidy = new Tidy();
tidy.setShowErrors(0);
tidy.setQuiet(true);
tidy.setErrout(null);
doc = tidy.parseDOM(in, null);

One of them may be enough already, these were all the options I found. Note that this will simply hide the messages, not do anything about them. There is also setForceOutput to get the output, even if errors were generated.

If you want to redirect the JTidy warnings to (say) a log4j logger, read this blog entry.

If you simply want them to go away (along with other console output), then use System.setOut() and/or System.setErr() to send the output to a file ... or a black hole.

For JTidy release 8 (or later), the Tidy.setMessageListener(TidyMessageListener) method deals with the messages more gracefully.

Alternatively, you could send a bug report to webmaster@yahoo.com. :-)

---

Writer out = new NullWriter();
PrintWriter dummyOut = new PrintWriter(out);
tidy.setErrout(dummyOut);

---

Looking at the documentation I found another method that seems a bit nicer to me in this particular case: setShowWarnings(boolean). This method will hide the warnings, but errors will still be thrown.

For more info look here: http://www.docjar.com/docs/api/org/w3c/tidy/Tidy.html#setShowWarnings(boolean)

I think this is the nicest solution, based on the answer of Joost:

Tidy tidy = new Tidy();
tidy.setShowErrors(0);
tidy.setShowWarnings(false);
tidy.setQuiet(true);

All three are necessary.
