Class SAXXIncluder

java.lang.Object
  |
  +--com.elharo.xml.xinclude.SAXXIncluder

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.ext.LexicalHandler

public class SAXXIncluder

extends java.lang.Object

implements org.xml.sax.ContentHandler, org.xml.sax.ext.LexicalHandler

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

The only current known bug is that the notation and unparsed entity information items are not included in the result infoset. Furthermore, processing instructions in the DTD are not included. Note that this is only relevant to the source infoset. The DOCTYPE declaration is specifically excluded from included infosets.

I also need to check how section 4.4.3.1 applies for inscope namespaces in included documents. Currently this is not an issue because I only include full documents, but it may become an an issue when XPointer support is added.

There's no XPointer support yet. Only full documents are included.

The xinclude:fallback element is not yet supported.

The parser used to drive this must support the LexicalHandler interface. It must also provide a Locator object. These are optional in SAX, but Xerces-J does support these features.
