Java compact2, compact3 org.xml.sax.ext Interface LexicalHandler（JDK8）

Method Detail

• startDTD

  void startDTD(String name,
                String publicId,
                String systemId)
         throws SAXException

  Report the start of DTD declarations, if any.

  This method is intended to report the beginning of the DOCTYPE declaration; if the document has no DOCTYPE declaration, this method will not be invoked.

  All declarations reported through DTDHandler or DeclHandler events must appear between the startDTD and endDTD events. Declarations are assumed to belong to the internal DTD subset unless they appear between startEntity and endEntity events. Comments and processing instructions from the DTD should also be reported between the startDTD and endDTD events, in their original order of (logical) occurrence; they are not required to appear in their correct locations relative to DTDHandler or DeclHandler events, however.

  Note that the start/endDTD events will appear within the start/endDocument events from ContentHandler and before the first startElement event.

  Parameters:

  name - The document type name.

  publicId - The declared public identifier for the external DTD subset, or null if none was declared.

  systemId - The declared system identifier for the external DTD subset, or null if none was declared. (Note that this is not resolved against the document base URI.)

  Throws:

  SAXException - The application may raise an exception.

  endDTD(), startEntity(java.lang.String)

• endDTD

  void endDTD()
       throws SAXException

  Report the end of DTD declarations.

  This method is intended to report the end of the DOCTYPE declaration; if the document has no DOCTYPE declaration, this method will not be invoked.

  Throws:

  SAXException - The application may raise an exception.

  See Also:

  startDTD(java.lang.String, java.lang.String, java.lang.String)

• startEntity

  void startEntity(String name)
            throws SAXException

  Report the beginning of some internal and external XML entities.

  The reporting of parameter entities (including the external DTD subset) is optional, and SAX2 drivers that report LexicalHandler events may not implement it; you can use the http://xml.org/sax/features/lexical-handler/parameter-entities feature to query or control the reporting of parameter entities.

  General entities are reported with their regular names, parameter entities have '%' prepended to their names, and the external DTD subset has the pseudo-entity name "[dtd]".

  When a SAX2 driver is providing these events, all other events must be properly nested within start/end entity events. There is no additional requirement that events from DeclHandler or DTDHandler be properly ordered.

  Note that skipped entities will be reported through the skippedEntity event, which is part of the ContentHandler interface.

  Because of the streaming event model that SAX uses, some entity boundaries cannot be reported under any circumstances:

  • general entities within attribute values
  • parameter entities within declarations

  These will be silently expanded, with no indication of where the original entity boundaries were.

  Note also that the boundaries of character references (which are not really entities anyway) are not reported.

  All start/endEntity events must be properly nested.

  Parameters:

  name - The name of the entity. If it is a parameter entity, the name will begin with '%', and if it is the external DTD subset, it will be "[dtd]".

  Throws:

  SAXException - The application may raise an exception.

  endEntity(java.lang.String), DeclHandler.internalEntityDecl(java.lang.String, java.lang.String), DeclHandler.externalEntityDecl(java.lang.String, java.lang.String, java.lang.String)

• endEntity

  void endEntity(String name)
          throws SAXException

  Report the end of an entity.

  Parameters:

  name - The name of the entity that is ending.

  Throws:

  SAXException - The application may raise an exception.

  See Also:

  startEntity(java.lang.String)

• startCDATA

  void startCDATA()
           throws SAXException

  Report the start of a CDATA section.

  The contents of the CDATA section will be reported through the regular characters event; this event is intended only to report the boundary.

  Throws:

  SAXException - The application may raise an exception.

  See Also:

  endCDATA()

• endCDATA

  void endCDATA()
         throws SAXException

  Report the end of a CDATA section.

  Throws:

  SAXException - The application may raise an exception.

  See Also:

  startCDATA()

• comment

  void comment(char[] ch,
               int start,
               int length)
        throws SAXException

  Report an XML comment anywhere in the document.

  This callback will be used for comments inside or outside the document element, including comments in the external DTD subset (if read). Comments in the DTD must be properly nested inside start/endDTD and start/endEntity events (if used).

  Parameters:

  ch - An array holding the characters in the comment.

  start - The starting position in the array.

  length - The number of characters to use from the array.

  Throws:

  SAXException - The application may raise an exception.
