Unicode to HTML entities

[Clodoaldo]

I was looking for a function to transform a unicode string into
htmlentities. Not only the usual html escaping thing but all
characters.

As I didn't find I wrote my own:

# -*- coding: utf-8 -*-
from htmlentitydefs import codepoint2name

def unicode2htmlent ities(u):

htmlentities = list()

for c in u:
if ord(c) < 128:
htmlentities.ap pend(c)
else:
htmlentities.ap pend('&%s;' % codepoint2name[ord(c)])

return ''.join(htmlent ities)

print unicode2htmlent ities(u'São Paulo')

Is there a function like that in one of python builtin modules? If not
is there a better way to do it?

'S&#227;o Paulo'

That was a fast answer. I would never find that myself.

Thanks, Clodoaldo

You might actually want:

>>cgi.escape(u' São Paulo & Espírito Santo').encode( 'ascii', 'xmlcharrefrepl ace')

'S&#227;o Paulo &amp; Esp&#237;rito Santo'

as you have to be sure to escape any ampersands in your unicode
string before doing the encode.

In many cases, the need to use html/xhtml entities can be avoided by
generating
utf8- coded pages.

Sure. All my pages are utf-8 encoded. The case I'm dealing with is an
email link which subject has non ascii characters like in:

<a href=mailto:exa mple@sample.com ?subject=Dúvida s>Mail to</a>

Somehow when the user clicks on the link the subject goes to his email
client with the non ascii chars as garbage.

And before someone points that I should not expose email addresses,
the email is only linked with the consent of the owner and the source
is obfuscated to make it harder for a robot to harvest it.

I will do it. Thanks.
