error msgs...

Hi,
 
While  I am using tidy I see messages on my console, like shown below:
 
line 1 column 150 - Error: <smallscreenignore> is not recognized!
This document has errors that must be fixed before
using HTML Tidy to generate a tidied up version.
 
I have tried to set up tidy as :
 
tidy.setXmlOut( false);
        tidy.setQuiet( true);
        tidy.setShowWarnings( false);
 
But I still get such messages, any idea how I could supress them?
