如何在Python中将HTML实体转换为Unicode，反之亦然？

回答：

您需要有BeautifulSoup。

from BeautifulSoup import BeautifulStoneSoup
import cgi
def HTMLEntitiesToUnicode(text):
    """Converts HTML entities to unicode.  For example '&' becomes '&'."""
    text = unicode(BeautifulStoneSoup(text, convertEntities=BeautifulStoneSoup.ALL_ENTITIES))
    return text
def unicodeToHTMLEntities(text):
    """Converts unicode to HTML entities.  For example '&' becomes '&'."""
    text = cgi.escape(text).encode('ascii', 'xmlcharrefreplace')
    return text
text = "&, ®, <, >, ¢, £, ¥, €, §, ©"
uni = HTMLEntitiesToUnicode(text)
htmlent = unicodeToHTMLEntities(uni)
print uni
print htmlent
# &, ®, <, >, ¢, £, ¥, €, §, ©
# &amp;, &#174;, &lt;, &gt;, &#162;, &#163;, &#165;, &#8364;, &#167;, &#169;
