As a basic example, below is a very basic HTML parser that uses the
:class:`HTMLParser` class to print out tags as they are encountered::
- from html.parser import HTMLParser
+ >>> from html.parser import HTMLParser
+ >>>
+ >>> class MyHTMLParser(HTMLParser):
+ ... def handle_starttag(self, tag, attrs):
+ ... print("Encountered a {} start tag".format(tag))
+ ... def handle_endtag(self, tag):
+ ... print("Encountered a {} end tag".format(tag))
+ ...
+ >>> page = """<html><h1>Title</h1><p>I'm a paragraph!</p></html>"""
+ >>>
+ >>> myparser = MyHTMLParser()
+ >>> myparser.feed(page)
+ Encountered a html start tag
+ Encountered a h1 start tag
+ Encountered a h1 end tag
+ Encountered a p start tag
+ Encountered a p end tag
+ Encountered a html end tag
- class MyHTMLParser(HTMLParser):
-
- def handle_starttag(self, tag, attrs):
- print "Encountered the beginning of a %s tag" % tag
-
- def handle_endtag(self, tag):
- print "Encountered the end of a %s tag" % tag
On Unix and Mac systems if you intend to install multiple versions of Python
using the same installation prefix (--prefix argument to the configure
script) you must take care that your primary python executable is not
-overwritten by the installation of a different versio. All files and
+overwritten by the installation of a different version. All files and
directories installed using "make altinstall" contain the major and minor
version and can thus live side-by-side. "make install" also creates
${prefix}/bin/python3 which refers to ${prefix}/bin/pythonX.Y. If you intend
