我将 OSX 10.6 和 python 2.7.1 与 BeautifulSoup 3.0 和 feedparser 5.01 一起使用。我正在尝试解析纽约时报的 RSS 提要,它会验证,而 Beautiful Soup 本身会很高兴地解析。
产生错误的最小代码是:
import feedparser
from BeautifulSoup import BeautifulSoup
feed = feedparser.parse("http://www.nytimes.com/services/xml/rss/nyt/GlobalHome.xml")
- 如果我使用 url 或使用 urllib2.urlopen 获取内容,它会失败。
- 我也尝试过字符集检测器。
错误块是:
/Users/user/Source/python/feed/BeautifulSoup.py:1553: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
elif data[:3] == '\xef\xbb\xbf':
/Users/user/Source/python/feed/BeautifulSoup.py:1556: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal

我非常感谢任何建议。
