## Detailed Description Receive notification of lexical events. This is an extension handler for that provides lexical information about an XML document. It does not provide information about document content. For those events, an application must register an instance of a ContentHandler. The order of events in this interface is very important, and mirrors the order of information in the document itself. For example, startDTD() and endDTD() events will occur before the first element in the document.

LexicalHandler::LexicalHandler | ( |  | ) |
Default constructor.
virtual LexicalHandler::~LexicalHandler | ( |  | ) | `[virtual]`
Destructor. ## Member Function Documentation
virtual void LexicalHandler::comment | ( | const XMLCh *const | chars,
|  | const unsigned int | length |
| ) |  |  | `[pure virtual]`
  Receive notification of comments. The Parser will call this method to report each occurence of a comment in the XML document. The application must not attempt to read from the array outside of the specified range. Parameters:
  | chars | The characters from the XML document.
  | length | The number of characters to read from the array.
  Exceptions:
  | SAXException | Any SAX exception, possibly wrapping another exception.
Implemented in DefaultHandler.
virtual void LexicalHandler::endCDATA | ( |  | ) | `[pure virtual]`
  Receive notification of the end of a CDATA section. The SAX parser will invoke this method at the end of each CDATA parsed. Exceptions:
  | SAXException | Any SAX exception, possibly wrapping another exception.
Implemented in DefaultHandler.
virtual void LexicalHandler::endDTD | ( |  | ) | `[pure virtual]`
  Receive notification of the end of the DTD declarations. The SAX parser will invoke this method at the end of the DTD Exceptions:
  | SAXException | Any SAX exception, possibly wrapping another exception.
Implemented in DefaultHandler.
virtual void LexicalHandler::endEntity | ( | const XMLCh *const | name | ) | `[pure virtual]`
  Receive notification of the end of an entity. The SAX parser will invoke this method at the end of an entity Parameters:
  | name | The name of the entity that is ending.
  Exceptions:
  | SAXException | Any SAX exception, possibly wrapping another exception.
Implemented in DefaultHandler.
virtual void LexicalHandler::startCDATA | ( |  | ) | `[pure virtual]`
  Receive notification of the start of a CDATA section. The SAX parser will invoke this method at the start of each CDATA parsed. Exceptions:
  | SAXException | Any SAX exception, possibly wrapping another exception.
Implemented in DefaultHandler.
virtual void LexicalHandler::startDTD | ( | const XMLCh *const | name,
|  | const XMLCh *const | publicId,
|  | const XMLCh *const | systemId |
| ) |  |  | `[pure virtual]`
  Receive notification of the start of the DTD declarations. The SAX parser will invoke this method at the start of the DTD 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.
  Exceptions:
  | SAXException | Any SAX exception, possibly wrapping another exception.
Implemented in DefaultHandler.
virtual void LexicalHandler::startEntity | ( | const XMLCh *const | name | ) | `[pure virtual]`
  Receive notification of the start of an entity. The SAX parser will invoke this method at the start of an entity Parameters:
  | name | The name of the entity that is starting.
  Exceptions:
  | SAXException | Any SAX exception, possibly wrapping another exception.
Implemented in DefaultHandler. The documentation for this class was generated from the following file: LexicalHandler.hpp
