All Implemented Interfaces:

IMarkupFilter

public final class HtmlProblemFinder

extends AbstractMarkupFilter

This is a markup inline filter which by default is not added to the list of markup filter. It can be added by means of subclassing Application.newMarkupParser() like

     public class MyApplication extends Application
     {
         ...
 	       public MarkupParser newMarkupParser()
         {
             final MarkupParser parser = new MarkupParser(new XmlPullParser())
                 {
                     public void initFilterChain()
                     {
                         appendMarkupFilter(new HtmlProblemFinder(HtmlProblemFinder.ERR_THROW_EXCEPTION));
                     }
                 };
             parser.configure(getSettings());
             return parser;
             }
 

The purpose of the filter is to find possible HTML issues and to log a warning.
