    • parse

      public void parse(InputSource poSource) throws IOException, SAXException
      Describe 'parse' method here.
      Specified by:
      parse in interface XMLReader
      Parameters:
      poSource - -
      Throws:
      IOException
      SAXException
    • setContentHandler

      public void setContentHandler(ContentHandler poHandler)
      Allow an application to register a content event handler. If the application does not register a content handler, all content events reported by the SAX parser will be silently ignored.

      Applications may register a new or different handler in the middle of a parse, and the SAX parser must begin using the new handler immediately.

      Specified by:
      setContentHandler in interface XMLReader
      Parameters:
      poHandler - a ContentHandler The XML content handler
      Throws:
      NullPointerException - If the handler argument is null
    • getContentHandler

      public ContentHandler getContentHandler()
      Return the content handler.
      Specified by:
      getContentHandler in interface XMLReader
      Returns:
      a ContentHandler The current content handler, or null if none has been registered.
