For real-world use you'll want to URL encode and entityify the text:

import cgi
import urllib

def google_link(text):
    text = text.group(1)
    return '<a href="%s">%s</a>' % (cgi.escape(urllib.quote(text)),
                                    cgi.escape(text))

re.sub(r"<google>(.*)</google>", google_link, "<google>foo bar</google>)
