SAXParserFactory ()

Protected constructor to force use of newInstance().

Public methods

getFeature

Added in API level 1

boolean Value of the requested property.

SAXNotSupportedException When the underlying XMLReader recognizes the property name but doesn't support the property.

getSchema

Added in API level 8
Schema getSchema ()

Gets the Schema object specified through the setSchema(Schema) method.

Returns
Schema the Schema object that was last set through the setSchema(Schema) method, or null if the method was not invoked since a SAXParserFactory is created.
Throws
UnsupportedOperationException For backward compatibility, when implementations for earlier versions of JAXP is used, this exception will be thrown.

isNamespaceAware

Added in API level 1
boolean isNamespaceAware ()

Indicates whether or not the factory is configured to produce parsers which are namespace aware.

Returns
boolean true if the factory is configured to produce parsers which are namespace aware; false otherwise.

isValidating

Added in API level 1
boolean isValidating ()

Indicates whether or not the factory is configured to produce parsers which validate the XML content during parse.

Returns
boolean true if the factory is configured to produce parsers which validate the XML content during parse; false otherwise.

isXIncludeAware

Added in API level 1
boolean isXIncludeAware ()

Get state of XInclude processing.

Returns
boolean current state of XInclude processing
Throws
UnsupportedOperationException For backward compatibility, when implementations for earlier versions of JAXP is used, this exception will be thrown.

newInstance

Added in API level 9
SAXParserFactory newInstance (String factoryClassName, 
                ClassLoader classLoader)

Returns an instance of the named implementation of SAXParserFactory.

Parameters
factoryClassName String
classLoader ClassLoader
Returns
SAXParserFactory
Throws
FactoryConfigurationError if factoryClassName is not available or cannot be instantiated.

newInstance

Added in API level 1
SAXParserFactory newInstance ()

Returns Android's implementation of SAXParserFactory. Unlike other Java implementations, this method does not consult system properties, property files, or the services API.

Returns
SAXParserFactory a new SAXParserFactory.
Throws
FactoryConfigurationError never. Included for API compatibility with other Java implementations.

newSAXParser

Added in API level 1
SAXParser newSAXParser ()

Creates a new instance of a SAXParser using the currently configured factory parameters.

Returns
SAXParser A new instance of a SAXParser.
Throws
ParserConfigurationException if a parser cannot be created which satisfies the requested configuration.
SAXException for SAX errors.

setFeature

Added in API level 1
void setFeature (String name, 
                boolean value)

Sets the particular feature in the underlying implementation of org.xml.sax.XMLReader. A list of the core features and properties can be found at http://www.saxproject.org/

All implementations are required to support the FEATURE_SECURE_PROCESSING feature. When the feature is

  • true: the implementation will limit XML processing to conform to implementation limits. Examples include entity expansion limits and XML Schema constructs that would consume large amounts of resources. If XML processing is limited for security reasons, it will be reported via a call to the registered fatalError(SAXParseException). See SAXParser parse methods for handler specification.
  • When the feature is false, the implementation will processing XML according to the XML specifications without regard to possible implementation limits.

Parameters
name String: The name of the feature to be set.
value boolean: The value of the feature to be set.
Throws
ParserConfigurationException if a parser cannot be created which satisfies the requested configuration.
SAXNotRecognizedException When the underlying XMLReader does not recognize the property name.
SAXNotSupportedException When the underlying XMLReader recognizes the property name but doesn't support the property.
NullPointerException If the name parameter is null.

setNamespaceAware

Added in API level 1
void setNamespaceAware (boolean awareness)

Specifies that the parser produced by this code will provide support for XML namespaces. By default the value of this is set to false.

Parameters
awareness boolean: true if the parser produced by this code will provide support for XML namespaces; false otherwise.

setSchema

Added in API level 8
void setSchema (Schema schema)

Set the Schema to be used by parsers created from this factory.

When a Schema is non-null, a parser will use a validator created from it to validate documents before it passes information down to the application.

When warnings/errors/fatal errors are found by the validator, the parser must handle them as if those errors were found by the parser itself. In other words, if the user-specified ErrorHandler is set, it must receive those errors, and if not, they must be treated according to the implementation specific default error handling rules.

A validator may modify the SAX event stream (for example by adding default values that were missing in documents), and a parser is responsible to make sure that the application will receive those modified event stream.

Initially, null is set as the Schema.

This processing will take effect even if the isValidating() method returns false.

It is an error to use the http://java.sun.com/xml/jaxp/properties/schemaSource property and/or the http://java.sun.com/xml/jaxp/properties/schemaLanguage property in conjunction with a non-null Schema object. Such configuration will cause a SAXException exception when those properties are set on a SAXParser.

Note for implementors

A parser must be able to work with any Schema implementation. However, parsers and schemas are allowed to use implementation-specific custom mechanisms as long as they yield the result described in the specification.

Parameters
schema Schema: Schema to use, null to remove a schema.
Throws
UnsupportedOperationException For backward compatibility, when implementations for earlier versions of JAXP is used, this exception will be thrown.

setValidating

Added in API level 1
void setValidating (boolean validating)

Specifies that the parser produced by this code will validate documents as they are parsed. By default the value of this is set to false.

Note that "the validation" here means a validating parser as defined in the XML recommendation. In other words, it essentially just controls the DTD validation. (except the legacy two properties defined in JAXP 1.2. See here for more details.)

To use modern schema languages such as W3C XML Schema or RELAX NG instead of DTD, you can configure your parser to be a non-validating parser by leaving the setValidating(boolean) method false, then use the setSchema(Schema) method to associate a schema to a parser.

Parameters
validating boolean: true if the parser produced by this code will validate documents as they are parsed; false otherwise.

setXIncludeAware

Added in API level 1
void setXIncludeAware (boolean state)

Set state of XInclude processing.

If XInclude markup is found in the document instance, should it be processed as specified in XML Inclusions (XInclude) Version 1.0.

XInclude processing defaults to false.

Parameters
state boolean: Set XInclude processing to true or false
Throws
UnsupportedOperationException For backward compatibility, when implementations for earlier versions of JAXP is used, this exception will be thrown.
