I wrote a function that converts a tuple of tuples into html. For
example:
In [9]: x
Out[9]:
('html',
('head', ('title', 'this is the title!')),
('body',
('h1', 'this is the header!'),
('p', 'paragraph one is boring.'),
('p',
'but paragraph 2 ',
('a', {'href': 'http://example.com'}, 'has a link'),
'!')))
In [10]: as_html(x, sys.stdout)
<html>
<head>
<title>this is the title!</title>
</head>
<body>
<h1>this is the header!</h1>
<p>paragraph one is boring.</p>
<p>but paragraph 2 <a href="http://example.com";>has a link</a>!</p>
</body>
</html>
I'd like to know ways to make it better (more efficient, able to deal
with enormous-size arguments, etc). How would I write this as a
generator?
Here's the definition for as_html:
def as_html(l, s):
"Convert a list or tuple into html and write it to stream s."
if isinstance(l, (tuple, list)):
tagname = l[0]
if isinstance(l[1], dict):
attributes = ' '.join(['%s="%s"' % (k, l[1][k]) for k in l[1]])
s.write('<%s %s>' % (tagname, attributes))
else:
s.write('<%s>' % tagname)
if tagname in ('html', 'head', 'body'):
s.write('\n\n')
for ll in l[1:]:
as_html(ll, s)
s.write('</%s>' % tagname)
if tagname not in ('a', 'b', 'ul'):
s.write('\n\n')
elif isinstance(l, str):
s.write(l)
All comments welcome. TIA
