美丽的汤不能找到一个CSS类，如果对象具有其他类，也 [英] Beautiful Soup cannot find a CSS class if the object has other classes, too

问题描述

如果一个页面有＆LT; D​​IV CLASS =1级＆GT; 和＆LT; p类=1级＆GT; ，那么 soup.findAll（真，'1级'）会找到他们。

if a page has <div class="class1"> and <p class="class1">, then soup.findAll(True, 'class1') will find them both.

如果有＆LT; p =类class1的类class2＆GT; ，虽然，它不会被发现。我如何找到与某一类的所有对象，无论他们是否有其他类，也？

If it has <p class="class1 class2">, though, it will not be found. How do I find all objects with a certain class, regardless of whether they have other classes, too?

推荐答案

万一有人遇到这个问题。 BeautifulSoup现在支持这样的：

Just in case anybody comes across this question. BeautifulSoup now supports this:

Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)]
Type "copyright", "credits" or "license" for more information.

In [1]: import bs4

In [2]: soup = bs4.BeautifulSoup('<div class="foo bar"></div>')

In [3]: soup(attrs={'class': 'bar'})
Out[3]: [<div class="foo bar"></div>]

此外，您不必键入的findAll了。

Also, you don't have to type findAll anymore.
