查找包含特定类的所有html元素

Question

I want BeautifulSoup to find all element in html page whose have a certain class. But they can also have extra classes. For example:

soup.findAll('tr', {'class': 'super_class1'})

This code only finds tr whose have only super_class1 . But I want it to find all tr whose contains this class such

<tr class='super_class1'>aaa</tr>

and

<tr class='super_class1 super_class2'>bbb</tr>

and

<tr class='super_class1 super_class15  super_class16'>ccc</tr>

Answer 1

This is a bug that has been fixed ( https://bugs.launchpad.net/beautifulsoup/+bug/410304 ); the problem is basically that the soup doesn't recognizes spaces in class name.

But if you have to use a version without the fix, the above link also provides a solution:

soup.findAll(True, {'class': re.compile(r'\bsuper_class1\b')})
