How to remove warnings in jtidy in java

Question

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 get 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 1.0 Strict//EN" InputStream: Document content looks like HTML 4.01 Transitional 1 warnings/errors were found! 

These alerts are displayed automatically on the console. But I do not want these warnings to be displayed on my console after starting

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

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

Answer 1

Looking at the documentation, I found several methods that can do what you want.

There is setShowErrors , setQuiet and setErrout . You can 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 already be enough, these were all the options that I found. Note that this will simply hide the messages, and not do anything about them. There is also setForceOutput to get the result, even if errors were generated.

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

If you just want them to leave (along with another console output), use System.setOut() and / or System.setErr() to send the output to a file ... or a black hole.

For version 8 (or later) JTidy, the Tidy.setMessageListener(TidyMessageListener) method handles messages more competently.

Answer 3

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

Answer 4

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

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

I think this is the nicest solution based on Joost's answer:

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

All three are necessary.
