SAX Exceptions
SAX presents all errors, including exceptions raised by
handler methods, to the application as instances of the SAXException
exception class or its
subclasses. Instances of this class have these methods:
getException( )
Returns an exception caught by the SAX parser, if
there was one, or None
if
there wasn’t one.
getMessage( )
Returns an explanation of the problem encountered
by the parser as a string for human consumption. The message
string may have been localized if the XMLReader
’s setLocale
method is called.
The following subclasses of SAXException
are defined by SAX.
SAXParseException
This exception is raised when there is a problem
parsing the document. Instances of this exception also conform
to the Locator
interface.
SAXNotRecognizedException
When an application attempts to set or query a feature or property that is not recognized by the parser, this exception is raised. Parsers are required to recognize all features and properties defined as part of the SAX 2 specification, even if they don’t support them.
SAXNotSupportedException
A parser raises this exception when the application attempts to set or query a feature or property that is recognized but not supported, or when the application attempts to set a feature or property to a value that is not supported.
