如何使用Python美丽的汤只得到1级navigableText？ [英] How to use python beautiful soup to get only the level 1 navigableText?

问题描述

我是用美丽的汤从这个例子HTML code中的文本：

I am using beautiful soup to get the text from this example html code:

....
<div style="s1">
    <div style="s2">Here is text 1</div>
    <div style="s3">Here is text 2</div>
Here is text 3 and this is what I want.
</div>
....

文本1和文本2是在同一水平2和3文本在上一级1.我只想要得到的文本3和使用这样的：

Text 1 and text 2 is at the same level 2 and the text 3 is at the upper level 1. I only want to get the text 3 and used this:

for anchor in tbody.findAll('div', style="s1"):
    review=anchor.text
    print review

但这些code让我所有的文字1,2,3。我怎么只得到了第一级的文本3？

But these code get me all the text 1,2,3. How do I only get the first level text 3?

推荐答案

是这样的：

for anchor in tbody.findAll('div', style="s1"):
    text = ''.join([x for x in anchor.contents if isinstance(x, bs4.element.NavigableString)])

工作。只要知道你还可以在那里得到的换行符，所以 .strip（）荷兰国际集团可能是必要的。

works. Just know that you'll also get the line breaks in there, so .strip()ing might be necessary.

例如：

for anchor in tbody.findAll('div', style="s1"):
    text = ''.join([x for x in anchor.contents if isinstance(x, bs4.element.NavigableString)])
    print([text])
    print([text.strip()])

打印

[u'\n\n\nHere is text 3 and this is what I want.\n']
[u'Here is text 3 and this is what I want.']

（我把它们放在列表，所以你可以看到新行）。

(I put them in lists so you could see the newlines.)
