HTML parser module.
|
|
|
|
USAGE
|
|
|
|
First make a HTML SAX handler object. Missing callback functions are
|
|
ignored. The object returned from callbacks is also ignored.
|
|
Note that a missing attribute value is stored as the value None
|
|
in the ListDict (ie. "<a href>" with lead to a {href: None} dict entry).
|
|
|
|
Used callbacks of a handler are:
|
|
|
|
- Start tag: <tag {attr1:value1, attr2:value2, ..}>
|
|
def start_element (tag, attrs)
|
|
@param tag: tag name
|
|
@type tag: Unicode string
|
|
@param attrs: tag attributes
|
|
@type attrs: ListDict
|
|
|
|
Additionally, there are error and warning callbacks:
|
|
|
|
- Parser warning.
|
|
def warning (msg)
|
|
@param msg: warning message
|
|
@type msg: Unicode string
|
|
|
|
- Parser error.
|
|
def error (msg)
|
|
@param msg: error message
|
|
@type msg: Unicode string
|
|
|
|
- Fatal parser error
|
|
def fatal_error (msg)
|
|
@param msg: error message
|
|
@type msg: Unicode string
|
|
|
|
EXAMPLE
|
|
|
|
# Create a new HTML parser object with the handler as parameter.
|
|
parser = HtmlParser.htmlsax.parser(handler)
|
|
# Feed data.
|
|
parser.feed("<html><body>Blubb</body></html>")
|
|
# Flush for finishing things up.
|
|
parser.flush()
