Class XIncludeHandler

  • All Implemented Interfaces:
    XMLComponent, XMLDocumentFilter, XMLDocumentSource, XMLDTDFilter, XMLDTDSource, XMLDocumentHandler, XMLDTDHandler
    Direct Known Subclasses:
    XPointerHandler

    public class XIncludeHandler
    extends Object
    implements XMLComponent, XMLDocumentFilter, XMLDTDFilter

    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.

        reset in interface XMLComponent
        Parameters:
        componentManager - The component manager.
        Throws:
        XNIException - Thrown by component on initialization error.
      • getRecognizedFeatures

        public String[] getRecognizedFeatures()
        Returns a list of feature identifiers that are recognized by this component. This method may return null if no features are recognized by this component.

        Throws:
        SAXNotRecognizedException - The component should not throw this exception.
        SAXNotSupportedException - The component should not throw this exception.
        XMLConfigurationException - Thrown for configuration error. In general, components should only throw this exception if it is really a critical error.
      • getRecognizedProperties

        startDocument in interface XMLDocumentHandler
        Parameters:
