这种情况发生在Windows 8上运行64.1位的Python 3.3.1，html.parser（这是Python内置的）。

.children的元素可以是NavigableStrings以及Tags。对于您的示例，它们是td元素之前和之后的空白。
您的代码的这种变化有望清楚地表明：
>>> rows = soup.findAll('tr')
>>> for r in rows:
... print("row:", r.name)
... for c in r.children:
... print("---")
... print(type(c))
... print(repr(c))
...
row: tr

<class 'bs4.element.NavigableString'>
