Beautifulsoup - nextSibling [英] Beautifulsoup - nextSibling

问题描述

我想用下面的获取内容我的家庭住址，但得到了AttributeError的：

I'm trying to get the content "My home address" using the following but got the AttributeError:

address = soup.find(text="Address:")
print address.nextSibling


    <td><b>Address:</b></td>

    <td>My home address</td>

什么是导航下来td标签拉内容的好方法吗？

What is a good way to navigate down td tag and pull the content?

推荐答案

的问题是，你找到了一个 NavigableString ，而不是＆LT; TD＆GT; 。此外 nextSibling 将寻找下一个 NavigableString 的或的标记因此，即使你有＆LT; TD方式＆gt; 它不会工作，你所期望的方式

The problem is that you have found a NavigableString, not the <td>. Also nextSibling will find the next NavigableString or Tag so even if you had the <td> it wouldn't work the way you expect.

这是你想要什么：

address = soup.find(text="Address:")
b_tag = address.parent
td_tag = b_tag.parent
next_td_tag = td_tag.findNext('td')
print next_td_tag.contents[0]

或者更简洁：

print soup.find(text="Address:").parent.parent.findNext('td').contents[0]

其实你可以只是做

Actually you could just do

print soup.find(text="Address:").findNext('td').contents[0]

由于 FindNext中只是调用接下来一遍又一遍，而接下来查找下一个元素的为解析的反复，直到它匹配。

Since findNext just calls next over and over again, and next finds the next element as parsed repeatedly until it matches.
