Question

我下面有一段HTML代码：

    <div class="user-tagline ">
      <span class="username " data-avatar="aaaaaaa">player1</span>
      <span class="user-rating">(1357)</span>
      <span class="country-flag-small flag-113" tip="Portugal"></span>
    </div>
    <div class="user-tagline ">
      <span class="username " data-avatar="bbbbbbb">player2</span>
      <span class="user-rating">(1387)</span>
      <span class="country-flag-small flag-70" tip="Indonesia"></span>
    </div>

我要从中提取“葡萄牙”，请注意span类是动态类，它并不总是class="country-flag-small flag-113"，但实际上是根据为此div块生成的国家/地区值进行的更改。

要获取player1和1357，我使用了以下繁琐的代码：

player1info = soup.findAll('div', attrs={'class':'user-tagline'})[0].text.split("\n")
player1 = player1info[1]
pscore1 = player1info[1].replace('(','').replace(')', '')

如果有人可以在这里与您共享更好的解决方案，我们将不胜感激。预先谢谢你

更新：

在提取了最初的HTML div信息之后，现在我想扩展它以提取整行的更多信息，这是该行：

<tr board-popover="" fen="r1bk2r1/1p2n3/pN6/1B1qQp2/P2Pp2p/1P6/2P2PPP/R3K1R1 b Q -" flip-board="1" highlight-squares="c4b6">

total moves (25)
playing date (Aug 9, 2017)

非常感谢您。

Answer 1

下面的代码怎么样？

用户属性在div下为3个范围的想法。因此，代码指向这些范围并提取数据。

from bs4 import BeautifulSoup

html = '''<html><body>   <div class="user-tagline ">
      <span class="username " data-avatar="aaaaaaa">player1</span>
      <span class="user-rating">(1357)</span>
      <span class="country-flag-small flag-113" tip="Portugal"></span>
    </div>
    <div class="user-tagline ">
      <span class="username " data-avatar="bbbbbbb">player2</span>
      <span class="user-rating">(1387)</span>
      <span class="country-flag-small flag-70" tip="Indonesia"></span>
    </div><body></html>'''

soup = BeautifulSoup(html, 'html.parser')

users = soup.findAll('div', attrs={'class': 'user-tagline'})
for user in users:
    user_properties = user.findAll('span')
    for idx, prop in enumerate(user):
        if idx == 1:
            print('user name: {}'.format(prop.text))
        elif idx == 3:
            print('user rating: {}'.format(prop.text))
        elif idx == 5:
            print('user country: {}'.format(prop.attrs['tip']))

输出

user name: player1
user rating: (1357)
user country: Portugal
user name: player2
user rating: (1387)
user country: Indonesia

Answer 2

这是一个更具可读性的解决方案：

div1 = soup.select("div.user-tagline")[0]
player1 = div1.select_one("span.user-rating").text
pscore1 = div1.select_one("span.country-flag-small").text

要提取所有div的数据，只需使用循环即可。并将“ 0”替换为“ i”。

Answer 3

如果您只对第一格感兴趣，可以这样做：

res = bsobj.find('div', {'class':'user-tagline'}).findAll('span')
print(res[0].text, res[1].text, res[2]['tip'])
