（bs4）试图区分HTML页面中的不同容器

Question

我有一个来自Parlament之家的网页。它有关于MP申报利益的信息，我想为我正在考虑的项目存储所有MP利益。你知道吗

root = 'https://publications.parliament.uk/pa/cm/cmregmem/160606/abbott_diane.htm'

根是一个例子网页。我希望我的输出是一本字典，因为有兴趣在不同的副标题和条目可以是一个列表。你知道吗

问题：如果你看这个页面，第一个兴趣点（就业和收入）不是包装在一个容器中，而是标题是一个

标记，没有连接到它下面的文本，所以我可以调用soup.find_all('p', {xlms='<p, {'xmlns':'http://www.w3.org/1999/xhtml') 但它会返回费用的标题，以及其他一些标题，比如她的名字，而不是它下面的文本。 这使得遍历标题和存储信息变得困难

遍历页面、存储每个标题以及每个标题下的信息的最佳方式是什么？你知道吗

Answer 1

像这样的方法可能有用：

import urllib.request
from bs4 import BeautifulSoup

ret = {}
page = urllib.request.urlopen("https://publications.parliament.uk/pa/cm/cmregmem/160606/abbott_diane.htm")
content = page.read().decode('utf-8')
soup = BeautifulSoup(content, 'lxml')
valid = False
value = ""

for i in soup.findAll('p'):
    if i.find('strong') and i.text is not None:
        # ignore first pass
        if valid:
           ret[key] = value
           value = ""
        valid = True
        key = i.text
    elif i.text is not None:
        value = value + " " + i.text

# get last entry
if key is not None:
    ret[key] = value

for x in ret:
    print (x)
    print (ret[x])
