New in version 2.0.
The 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.
-
| escape( |
data[, 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.
-
| unescape( |
data[, entities]) |
- Unescape "&", "<",
and ">" in a string of data.
You can unescape 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.
New in version 2.3.
-
| quoteattr( |
data[, entities]) |
- Similar to escape(), but also prepares data to be
used as an attribute value. The return value is a quoted version of data with
any additional required replacements. quoteattr() will select a
quote character based on the content of data, attempting to avoid encoding any
quote characters in the string. If both single- and double-quote characters are already in
data, the double-quote characters will be encoded and data will be
wrapped in doule-quotes. The resulting string can be used directly as an attribute value:
>>> print "<element attr=%s>" % quoteattr("ab ' cd \" ef")
<element attr="ab ' cd " ef">
This function is useful when generating attribute values for HTML or any SGML using the
reference concrete syntax. New in version 2.2.
-
| class XMLGenerator( |
[out[, encoding]]) |
- This class implements the ContentHandler interface by writing SAX
events back into an XML document. In other words, using an XMLGenerator
as the content handler will reproduce the original document being parsed. out
should be a file-like object which will default to sys.stdout. encoding
is the encoding of the output stream which defaults to
'iso-8859-1'.
-
| class XMLFilterBase( |
base) |
- This class is designed to sit between an 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.
-
| prepare_input_source( |
source[, base]) |
- This function takes an input source and an optional base URL and returns a fully
resolved InputSource object ready for reading. The input source can
be given as a string, a file-like object, or an InputSource object;
parsers will use this function to implement the polymorphic source argument to
their parse() method.
