1. class XIncludeFilter extends XMLFilterImpl

   

   This is a SAX filter which resolves all XInclude include elements before passing them on to the client application.

   This is a SAX filter which resolves all XInclude include elements before passing them on to the client application. Currently this class has the following known deviation from the XInclude specification:

   1. XPointer is not supported.

   Furthermore, I would definitely use a new instance of this class for each document you want to process. I doubt it can be used successfully on multiple documents. Furthermore, I can virtually guarantee that this class is not thread safe. You have been warned.

   Since this class is not designed to be subclassed, and since I have not yet considered how that might affect the methods herein or what other protected methods might be needed to support subclasses, I have declared this class final. I may remove this restriction later, though the use-case for subclassing is weak. This class is designed to have its functionality extended via a horizontal chain of filters, not a vertical hierarchy of sub and superclasses.

   To use this class:

   • Construct an XIncludeFilter object with a known base URL
   • Pass the XMLReader object from which the raw document will be read to the setParent() method of this object.
   • Pass your own ContentHandler object to the setContentHandler() method of this object. This is the object which will receive events from the parsed and included document.
   • Optional: if you wish to receive comments, set your own LexicalHandler object as the value of this object's http://xml.org/sax/properties/lexical-handler property. Also make sure your LexicalHandler asks this object for the status of each comment using insideIncludeElement before doing anything with the comment.
   • Pass the URL of the document to read to this object's parse() method

   e.g.

   val includer = new XIncludeFilter(base)
   includer setParent parser
   includer setContentHandler new SAXXIncluder(System.out)
   includer parse args(i)

2. class XIncluder extends ContentHandler with LexicalHandler

   

   XIncluder is a SAX ContentHandler that writes its XML document onto an output stream after resolving all xinclude:include elements.
