问题描述

我正在尝试使用 Python->Beautiful Soup 解析一个看起来像这样的网页:

I have am trying to parse a webpage that looks like this with Python->Beautiful Soup:

我正在尝试提取突出显示的 td div 的内容.目前我可以通过

I am trying to extract the contents of the highlighted td div. Currently I can get all the divs by

alltd = soup.findAll('td')

   
for td in alltd:
    print td

但我试图缩小范围以搜索tablebox"类中的 tds这仍然可能会返回 30+，但比 300+ 更易于管理.

But I am trying to narrow the scope of that to search the tds in the class "tablebox" which still will probably return 30+ but is more managable a number than 300+.

如何提取上图中突出显示的 td 的内容?

How can I extract the contents of the highlighted td in picture above?

推荐答案

BeautifulSoup 在一个元素中找到的任何元素仍然具有与该父元素相同的类型 - 即可以调用各种方法，这很有用.

It is useful to know that whatever elements BeautifulSoup finds within one element still have the same type as that parent element - that is, various methods can be called.

所以这是您的示例的一些工作代码:

So this is somewhat working code for your example:

soup = BeautifulSoup(html)
divTag = soup.find_all("div", {"class": "tablebox"})

for tag in divTag:
    tdTags = tag.find_all("td", {"class": "align-right"})
    for tag in tdTags:
        print tag.text

这将打印所有具有align-right"类的 td 标签的所有文本；具有父 div 类的tablebox".

This will print all the text of all the td tags with the class of "align-right" that have a parent div with the class of "tablebox".
