Class PostFilterByLanguage

java.lang.Object

edu.gvsu.kurmasz.zawilinski.PostFilterByLanguage

All Implemented Interfaces:

PostFilter

public class PostFilterByLanguage
extends Object
implements PostFilter

Keep only those pages that contain some data for the specified language and remove the trailing level 2 language header left by the prefilter.

IMPORTANT! This filter is written specifically to run after the LanguagePrefilter SAX filter is applied. This SAX filter assures that all text segments begin with the expected language string (e.g., "==Polish=="). If you don't apply the SAX filter, you need a different post-filter that checks to see if the revision text contains the languageString.
