[New-bugs-announce] [issue15120] Different behavior of html.parser.HTMLParser

Thu Jun 21 12:00:39 CEST 2012

New submission from hansokumake <hansokumake at seznam.cz>:

I tried this example from the documentation:

from html.parser import HTMLParser

class MyHTMLParser(HTMLParser):
    def handle_starttag(self, tag, attrs):
        print("Encountered a start tag:", tag)
    def handle_endtag(self, tag):
        print("Encountered an end tag :", tag)
    def handle_data(self, data):
        print("Encountered some data  :", data)

parser = MyHTMLParser(strict=False)
parser.feed('<html><head><title>Test</title></head>'
            '<body><h1>Parse me!</h1></body></html>')

According to documentation the output should be like this:
Encountered a start tag: html
Encountered a start tag: head
Encountered a start tag: title
Encountered some data  : Test
Encountered an end tag : title
Encountered an end tag : head
Encountered a start tag: body
Encountered a start tag: h1
Encountered some data  : Parse me!
Encountered an end tag : h1
Encountered an end tag : body
Encountered an end tag : html

but Python produced this:
Encountered some data  : <html>
Encountered some data  : <head>
Encountered some data  : <title>
Encountered some data  : Test
Encountered an end tag : title
Encountered an end tag : head
Encountered some data  : <body>
Encountered some data  : <h1>
Encountered some data  : Parse me!
Encountered an end tag : h1
Encountered an end tag : body
Encountered an end tag : html

If strict is set to True, it works correctly.
