使用BeautifulSoup提取标签中的内容 [英] Extract content within a tag with BeautifulSoup

问题描述

我想提取内容Hello world.请注意，页面上还有多个<table>和相似的<td colspan="2">:

I'd like to extract the content Hello world. Please note that there are multiples <table> and similar <td colspan="2"> on the page as well:

<table border="0" cellspacing="2" width="800">
  <tr>
    <td colspan="2"><b>Name: </b>Hello world</td>
  </tr>
  <tr>
...

我尝试了以下操作:

hello = soup.find(text='Name: ')
hello.findPreviousSiblings

但是它什么也没返回.

此外，我在提取My home address时遇到了以下问题:

In addition, I'm also having problem with the following extracting the My home address:

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

<td>My home address</td>

我也使用相同的方法搜索text="Address: "，但是如何导航到下一行并提取<td>的内容?

I'm also using the same method to search for the text="Address: " but how do I navigate down to the next line and extract the content of <td>?

推荐答案

contents运算符非常适合从<tag>text</tag>提取text.

The contents operator works well for extracting text from <tag>text</tag> .

<td>My home address</td>示例:

s = '<td>My home address</td>'
soup =  BeautifulSoup(s)
td = soup.find('td') #<td>My home address</td>
td.contents #My home address

<td><b>Address:</b></td>示例:

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

s = '<td><b>Address:</b></td>'
soup =  BeautifulSoup(s)
td = soup.find('td').find('b') #<b>Address:</b>
td.contents #Address:
