美丽的汤从标签

美丽的汤文档提供属性.contents和。孩子访问给定的标签（列表和迭代分别）的孩子们是标签（未通航字符串）的孩子，包括通航字符串和标签。我只想类型标签的孩子。美丽的汤从标签

我目前正在完成这个用list理解：

rows=[x for x in table.tbody.children if type(x)==bs4.element.Tag]

，但我不知道是否有一个更好/更Python /内置的方式得到的只是标签的孩子。

'table.tbody.find_all（真，递归= FALSE）'（我没试过） – jfs

[你可以发布自己的回答（http://blog.stackoverflow.com/2011/07/its-ok-to-ask-and-answer-your-own-questions/）：包括链接到该文档，可运行代码例如与输入/输出 – jfs

感谢J.F.Sebastian，下面的工作：

rows=table.tbody.find_all(True, recursive=False)

文档浏览：http://www.crummy.com/software/BeautifulSoup/bs4/doc/#true

就我而言，我需要在表中的实际行，所以我结束了使用以下，这是更精确，我认为更易读：

rows=table.tbody.find_all('tr')

同样，文档：http://www.crummy.com/software/BeautifulSoup/bs4/doc/#navigating-using-tag-names

我相信这是不是通过标签的所有孩子迭代更好的办法。

曾与下面的输入：
