On Windows, you can use Internet Explorer via COM:

>>> import urllib
>>> print urllib.urlopen('http://localhost/javascript.html').read()
<html>
<body>
<script>
document.write('Hello, World!')
</script>
</body>
</html>
>>> from win32com.client.gencache import EnsureDispatch
>>> ie = EnsureDispatch('InternetExplorer.Application')
>>> ie.Navigate('http://localhost/javascript.html')
>>> print ie.Document.documentElement.innerHTML
<HEAD></HEAD>
<BODY>
<SCRIPT>
document.write('Hello, World!')
</SCRIPT>
Hello, World! </BODY>
>>>
