|
The module \module{xml.sax.saxutils} contains a number of classes and
|
|
functions that are commonly useful when creating SAX applications,
|
|
either in direct use, or as base classes.
|
|
|
|
\begin{funcdesc}{escape}{data\optional{, entities}}
|
|
Escape \&, <, and > in a string of data.
|
|
|
|
You can escape other strings of data by passing a dictionary as the
|
|
optional entities parameter. The keys and values must all be
|
|
strings; each key will be replaced with its corresponding value.
|
|
\end{funcdesc}
|
|
|
|
\begin{classdesc}{XMLGenerator}{\optional{out\optional{, encoding}}}
|
|
This class implements the \class{ContentHandler} interface by
|
|
writing SAX events back into an XML document. In other words, using
|
|
an \class{XMLGenerator} as the content handler will reproduce the
|
|
original document being parsed. \var{out} should be a file-like
|
|
object which will default to \var{sys.stdout}. \var{encoding} is the
|
|
encoding of the output stream which defaults to \code{'iso-8859-1'}.
|
|
\end{classdesc}
|
|
|
|
\begin{classdesc}{XMLFilterBase}{base}
|
|
This class is designed to sit between an \class{XMLReader} and the
|
|
client application's event handlers. By default, it does nothing
|
|
but pass requests up to the reader and events on to the handlers
|
|
unmodified, but subclasses can override specific methods to modify
|
|
the event stream or the configuration requests as they pass through.
|
|
\end{classdesc}
|
|
|
|
\begin{funcdesc}{prepare_input_source}{source\optional{, base}}
|
|
This function takes an input source and an optional base URL and
|
|
returns a fully resolved \class{InputSource} object ready for
|
|
reading. The input source can be given as a string, a file-like
|
|
object, or an \class{InputSource} object; parsers will use this
|
|
function to implement the polymorphic \var{source} argument to their
|
|
\method{parse()} method.
|
|
\end{funcdesc}
