XIncludeHandler

public class XIncludeHandler extends Object implements org.apache.xerces.xni.parser.XMLDTDFilter, org.apache.xerces.xni.parser.XMLDocumentFilter, org.apache.xerces.xni.parser.XMLComponent

This is a pipeline component which performs XInclude handling, according to the W3C specification for XML Inclusions.

This component analyzes each event in the pipeline, looking for <include> elements. An <include> element is one which has a namespace of http://www.w3.org/2001/XInclude and a localname of include. When it finds an <include> element, it attempts to include the file specified in the href attribute of the element. If inclusion succeeds, all children of the <include> element are ignored (with the exception of checking for invalid children as outlined in the specification). If the inclusion fails, the <fallback> child of the <include> element is processed.

See the XInclude specification for more information on how XInclude is to be used.

This component requires the following features and properties from the component manager that uses it:

  • http://xml.org/sax/features/allow-dtd-events-after-endDTD
  • http://apache.org/xml/properties/internal/error-reporter
  • http://apache.org/xml/properties/internal/entity-resolver
Optional property:
  • http://apache.org/xml/properties/input-buffer-size
Furthermore, the NamespaceContext used in the pipeline is required to be an instance of XIncludeNamespaceSupport.

Currently, this implementation has only partial support for the XInclude specification. Specifically, it is missing support for XPointer document fragments. Thus, only whole documents can be included using this component in the pipeline.
