Whenever you put a URL into an HTML file you need to escape it, so
naturally you will also need to unescape it when it is retrieved from the
file. However, whatever you use to parse the HMTL ought to be unescaping
text and attributes as part of the parsing process, so you shouldn't need a
separate function for this.
e.g.
>>> from BeautifulSoup import BeautifulSoup
>>> soup = BeautifulSoup('''<a href="http://www.example.com/parrot.php?x=1
&y=2">link</a>''')
>>> soup.contents[0]['href']
u'http://www.example.com/parrot.php?x=1&y=2'
>>>
Even Python's builtin HTMLParser class will do this for you. What parser
are you using?
