Interface DocumentHandler

Method Detail

• setDocumentLocator

  void setDocumentLocator(Locator locator)

  Deprecated. 
  Receive an object for locating the origin of SAX document events.

  SAX parsers are strongly encouraged (though not absolutely required) to supply a locator: if it does so, it must supply the locator to the application by invoking this method before invoking any of the other methods in the DocumentHandler interface.

  The locator allows the application to determine the end position of any document-related event, even if the parser is not reporting an error. Typically, the application will use this information for reporting its own errors (such as character content that does not match an application's business rules). The information returned by the locator is probably not sufficient for use with a search engine.

  Note that the locator will return correct information only during the invocation of the events in this interface. The application should not attempt to use it at any other time.

  Parameters:

  locator - An object that can return the location of any SAX document event.

  Locator

• startDocument

  void startDocument()
                     throws SAXException

  Deprecated. 
  Receive notification of the beginning of a document.

  The SAX parser will invoke this method only once, before any other methods in this interface or in DTDHandler (except for setDocumentLocator).

  Throws:

  SAXException - Any SAX exception, possibly wrapping another exception.

• endDocument

  void endDocument()
                   throws SAXException

  Deprecated. 
  Receive notification of the end of a document.

  The SAX parser will invoke this method only once, and it will be the last method invoked during the parse. The parser shall not invoke this method until it has either abandoned parsing (because of an unrecoverable error) or reached the end of input.

  Throws:

  SAXException - Any SAX exception, possibly wrapping another exception.

• startElement

  void startElement(String name,
                  AttributeList atts)
                    throws SAXException

  Deprecated. 
  Receive notification of the beginning of an element.

  The Parser will invoke this method at the beginning of every element in the XML document; there will be a corresponding endElement() event for every startElement() event (even when the element is empty). All of the element's content will be reported, in order, before the corresponding endElement() event.

  If the element name has a namespace prefix, the prefix will still be attached. Note that the attribute list provided will contain only attributes with explicit values (specified or defaulted): #IMPLIED attributes will be omitted.

  Parameters:

  name - The element type name.

  atts - The attributes attached to the element, if any.

  Throws:

  SAXException - Any SAX exception, possibly wrapping another exception.

  See Also:

  endElement(java.lang.String), AttributeList

• endElement

  void endElement(String name)
                  throws SAXException

  Deprecated. 
  Receive notification of the end of an element.

  The SAX parser will invoke this method at the end of every element in the XML document; there will be a corresponding startElement() event for every endElement() event (even when the element is empty).

  If the element name has a namespace prefix, the prefix will still be attached to the name.

  Parameters:

  name - The element type name

  Throws:

  SAXException - Any SAX exception, possibly wrapping another exception.

• characters

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

  Deprecated. 
  Receive notification of character data.

  The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information.

  The application must not attempt to read from the array outside of the specified range.

  Note that some parsers will report whitespace using the ignorableWhitespace() method rather than this one (validating parsers must do so).

  Parameters:

  ch - The characters from the XML document.

  start - The start position in the array.

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

  Throws:

  SAXException - Any SAX exception, possibly wrapping another exception.

  See Also:

  ignorableWhitespace(char[], int, int), Locator

• ignorableWhitespace

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

  Deprecated. 
  Receive notification of ignorable whitespace in element content.

  Validating Parsers must use this method to report each chunk of ignorable whitespace (see the W3C XML 1.0 recommendation, section 2.10): non-validating parsers may also use this method if they are capable of parsing and using content models.

  SAX parsers may return all contiguous whitespace in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information.

  The application must not attempt to read from the array outside of the specified range.

  Parameters:

  ch - The characters from the XML document.

  start - The start position in the array.

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

  Throws:

  SAXException - Any SAX exception, possibly wrapping another exception.

  See Also:

  characters(char[], int, int)

• processingInstruction

  void processingInstruction(String target,
                           String data)
                             throws SAXException

  Deprecated. 
  Receive notification of a processing instruction.

  The Parser will invoke this method once for each processing instruction found: note that processing instructions may occur before or after the main document element.

  A SAX parser should never report an XML declaration (XML 1.0, section 2.8) or a text declaration (XML 1.0, section 4.3.1) using this method.

  Parameters:

  target - The processing instruction target.

  data - The processing instruction data, or null if none was supplied.

  Throws:

  SAXException - Any SAX exception, possibly wrapping another exception.
