Class SimpleHTMLFragment.SAXFilter

java.lang.Object

org.dspace.app.xmlui.wing.element.SimpleHTMLFragment.SAXFilter

All Implemented Interfaces:

ContentHandler, LexicalHandler

Enclosing class:

SimpleHTMLFragment

public static class SimpleHTMLFragment.SAXFilter
extends Object
implements ContentHandler, LexicalHandler

This is a simple SAX Handler that filters out start and end documents. This class is needed for two reasons, 1) namespaces need to be corrected from the originating HTML fragment, 2) to get around a JDOM bug where it can not output SAX events for just a document fragment. Since it only works with documents this class was created to filter out the events.

As far as I can tell, the first time the bug was identified is in the following email, point #1: http://www.servlets.com/archive/servlet/ReadMsg?msgId=491592&listName=jdom-interest

I, Scott Phillips, checked the JDOM CVS source tree on 3-8-2006 and the bug had not been patched at that time.
