Detailed Documentation
The DOMSerializer serializes a DOM document into a sequence of SAX events which are reported to the registered SAX event handlers.
The DOMWriter uses a DOMSerializer with an XMLWriter to serialize a DOM document into textual XML.
Methods
void serialize(const Node* pNode)
Serializes a DOM node and its children into a sequence of SAX events, which are reported to the registered SAX event handlers.
virtual void setEntityResolver(EntityResolver* pResolver)
Allow an application to register an entity resolver.
If the application does not register an entity resolver, the XMLReader will perform its own default resolution.
Applications may register a new or different resolver in the middle of a parse, and the SAX parser must begin using the new resolver immediately.
virtual EntityResolver* getEntityResolver() const
Return the current entity resolver.
virtual void setDTDHandler(DTDHandler* pDTDHandler)
Allow an application to register a DTD event handler.
If the application does not register a DTD handler, all DTD 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.
virtual DTDHandler* getDTDHandler() const
Return the current DTD handler.
virtual void setContentHandler(ContentHandler* pContentHandler)
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.
virtual ContentHandler* getContentHandler() const
Return the current content handler.
virtual void setErrorHandler(ErrorHandler* pErrorHandler)
Allow an application to register an error event handler.
If the application does not register an error handler, all error events reported by the SAX parser will be silently ignored; however, normal processing may not continue. It is highly recommended that all SAX applications implement an error handler to avoid unexpected bugs.
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.
virtual ErrorHandler* getErrorHandler() const
Return the current error handler.
virtual void setFeature( const XMLString& featureId, bool state )
Set the state of a feature.
The feature name is any fully-qualified URI. It is possible for an XMLReader to expose a feature value but to be unable to change the current value. Some feature values may be immutable or mutable only in specific contexts, such as before, during, or after a parse.
All XMLReaders are required to support setting http://xml.org/sax/features/namespaces to true and http://xml.org/sax/features/namespace-prefixes to false.
virtual bool getFeature(const XMLString& featureId) const
Look up the value of a feature.
The feature name is any fully-qualified URI. It is possible for an XMLReader to recognize a feature name but temporarily be unable to return its value. Some feature values may be available only in specific contexts, such as before, during, or after a parse. Also, some feature values may not be programmatically accessible. (In the case of an adapter for SAX1 Parser, there is no implementation-independent way to expose whether the underlying parser is performing validation, expanding external entities, and so forth.)
All XMLReaders are required to recognize the http://xml.org/sax/features/namespaces and the http://xml.org/sax/features/namespace-prefixes feature names. Implementors are free (and encouraged) to invent their own features, using names built on their own URIs.
virtual void setProperty( const XMLString& propertyId, const XMLString& value )
Set the value of a property.
The property name is any fully-qualified URI. It is possible for an XMLReader to recognize a property name but to be unable to change the current value. Some property values may be immutable or mutable only in specific contexts, such as before, during, or after a parse.
XMLReaders are not required to recognize setting any specific property names, though a core set is defined by SAX2.
This method is also the standard mechanism for setting extended handlers.
virtual void setProperty( const XMLString& propertyId, void* value )
Set the value of a property.
See also setProperty(const XMLString&, const XMLString&).
virtual void* getProperty(const XMLString& propertyId) const
Look up the value of a property.
String values are returned as XMLChar* The property name is any fully-qualified URI. It is possible for an XMLReader to recognize a property name but temporarily be unable to return its value. Some property values may be available only in specific contexts, such as before, during, or after a parse.
XMLReaders are not required to recognize any specific property names, though an initial core set is documented for SAX2.
Implementors are free (and encouraged) to invent their own properties, using names built on their own URIs.
virtual void parse(InputSource* pSource)
The DOMSerializer cannot parse an InputSource, so this method simply throws an XMLException when invoked.
virtual void parse(const XMLString& systemId)
The DOMSerializer cannot parse from a system identifier, so this method simply throws an XMLException when invoked.
virtual void parseMemoryNP( const char* xml, std::size_t size )
The DOMSerializer cannot parse from a system identifier, so this method simply throws an XMLException when invoked.
