+
+The \module{xml.sax} package provides a number of modules which
+implement the Simple API for XML (SAX) interface for Python. The
+package itself provides the SAX exceptions and the convenience
+functions which will be most used by users of the SAX API.
+
+The convenience functions are:
+
+\begin{funcdesc}{make_parser}{\optional{parser_list}}
+ Create and return a SAX \class{XMLReader} object. The first parser
+ found will be used. If \var{parser_list} is provided, it must be a
+ sequence of strings which name modules that have a function named
+ \function{create_parser()}. Modules listed in \var{parser_list}
+ will be used before modules in the default list of parsers.
+\end{funcdesc}
+
+\begin{funcdesc}{parse}{filename_or_stream, handler\optional{, error_handler}}
+ Create a SAX parser and use it to parse a document. The document,
+ passed in as \var{filename_or_stream}, can be a filename or a file
+ object. The \var{handler} parameter needs to be a SAX
+ \class{ContentHandler} instance. If \var{error_handler} is given,
+ it must be a SAX \class{ErrorHandler} instance; if omitted,
+ \exception{SAXParseException} will be raised on all errors. There
+ is no return value; all work must be done by the \var{handler}
+ passed in.
+\end{funcdesc}
+
+\begin{funcdesc}{parseString}{string, handler\optional{, error_handler}}
+ Similar to \function{parse()}, but parses from a buffer \var{string}
+ received as a parameter.
+\end{funcdesc}
+
+
+The SAX exceptions are also provided here:
+
+\begin{excclassdesc}{SAXException}{msg\optional{, exception}}
+ Encapsulate an XML error or warning. This class can contain basic
+ error or warning information from either the XML parser or the
+ application: it can be subclassed to provide additional
+ functionality or to add localization. Note that although the
+ handlers defined in the \class{ErrorHandler} interface receive
+ instances of this exception, it is not required to actually raise
+ the exception --- it is also useful as a container for information.
+
+ When instantiated, \var{msg} should be a human-readable description
+ of the error. The optional \var{exception} parameter, if given,
+ should be \code{None} or an exception that was caught by the parsing
+ code and is being passed along as information.
+
+ This is the base class for the other SAX exception classes.
+\end{excclassdesc}
+
+\begin{excclassdesc}{SAXParseException}{msg, exception, locator}
+ Subclass of \exception{SAXException} raised on parse errors.
+ Instances of this class are passed to the methods of the SAX
+ \class{ErrorHandler} interface to provide information about the
+ parse error. This class supports the SAX \class{Locator} interface
+ as well as the \class{SAXException} interface.
+\end{excclassdesc}
+
+\begin{excclassdesc}{SAXNotRecognizedException}{msg\optional{, exception}}
+ Subclass of \exception{SAXException} raised when a SAX
+ \class{XMLReader} is confronted with an unrecognized feature or
+ property. SAX applications and extensions may use this class for
+ similar purposes.
+\end{excclassdesc}
+
+\begin{excclassdesc}{SAXNotSupportedException}{msg\optional{, exception}}
+ Subclass of \exception{SAXException} raised when a SAX
+ \class{XMLReader} is asked to enable a feature that is not
+ supported, or to set a property to a value that the implementation
+ does not support. SAX applications and extensions may use this
+ class for similar purposes.
+\end{excclassdesc}

+ \seetitle[http://www.megginson.com/SAX/]{SAX: The Simple API for
+ XML}{This site is the focal point for the definition of
+ the SAX API. It provides a Java implementation and online
+ documentation. Links to implementations and historical
+ information are also available.}

+
+
+\subsection{SAXException Objects \label{saxexception-objects}}
+
+The \class{SAXException} exception class supports the following
+methods:
+
+\begin{methoddesc}[SAXException]{getMessage}{}
+ Return a human-readable message describing the error condition.
+\end{methoddesc}
+
+\begin{methoddesc}[SAXException]{getException}{}
+ Return an encapsulated exception object, or \code{None}.
+\end{methoddesc}
