此页包含多个嵌套的div和表。在使用BeautifulSoup时需要帮助 只分析信息-1信息-2。。。info-6和URL-1和URL-2。在

我看了BeautifulSoup的文档，没什么帮助。也请推荐一些漂亮的参考文档，用于分析复杂网页的书。在

谢谢你的帮助，谢谢！在

在我看来，你会想要这样的东西：

from BeautifulSoup import BeautifulSoup
import re
soup = BeautifulSoup(theXMLAsAString)
results = soup.findAll(re.compile('info - [1-6]'))
for r in results:
    myurl = r.parent.href

这段代码没有经过测试，但是它是如何使用beauthoulsoup的基本思想。在
