## Class XIncludeHandler

- java.lang.Object
- - org.apache.xerces.xinclude.XIncludeHandler

- All Implemented Interfaces:
    org.apache.xerces.xni.parser.XMLComponent, org.apache.xerces.xni.parser.XMLDocumentFilter, org.apache.xerces.xni.parser.XMLDocumentSource, org.apache.xerces.xni.parser.XMLDTDFilter, org.apache.xerces.xni.parser.XMLDTDSource, org.apache.xerces.xni.XMLDocumentHandler, org.apache.xerces.xni.XMLDTDHandler
  Direct Known Subclasses:
    XPointerHandler

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

          protected boolean isFallbackElement(org.apache.xerces.xni.QName element)

      Checks if the element is an <fallback> element. The element must have the XInclude namespace, and a local name of "fallback".
      Parameters:

    - #### sameBaseURIAsIncludeParent

          protected boolean sameBaseURIAsIncludeParent()

      Returns true if the current [base URI] is the same as the [base URI] that was in effect on the include parent. This method should only be called when the current element is a top level included element, i.e. the direct child of a fallback element, or the root elements in an included document. The "include parent" is the element which, in the result infoset, will be the direct parent of the current element.
      Returns:
        true if the [base URIs] are the same string

    - #### sameLanguageAsIncludeParent

          protected boolean sameLanguageAsIncludeParent()

      Returns true if the current [language] is equivalent to the [language] that was in effect on the include parent, taking case-insensitivity into account as per [RFC 3066]. This method should only be called when the current element is a top level included element, i.e. the direct child of a fallback element, or the root elements in an included document. The "include parent" is the element which, in the result infoset, will be the direct parent of the current element.
      Returns:
        true if the [language] properties have the same value taking case-insensitivity into account as per [RFC 3066].

          protected org.apache.xerces.xni.XMLAttributes processAttributes(org.apache.xerces.xni.XMLAttributes attributes)

      Processes the XMLAttributes object of startElement() calls. Performs the following tasks:
      - If the element is a top level included item whose [base URI] is different from the [base URI] of the include parent, then an xml:base attribute is added to specify the true [base URI]
      - For all namespace prefixes which are in-scope in an included item, but not in scope in the include parent, a xmlns:prefix attribute is added
      - For all attributes with a type of ENTITY, ENTITIES or NOTATIONS, the notations and unparsed entities are processed as described in the spec, sections 4.5.1 and 4.5.2
      Parameters:
        `attributes` -
