我试图从这个 HTML 代码中提取“T”、“0-0”和“（2 OT）”。我开始编写下面的代码，但新手太多，无法弄清楚。谢谢你的帮助。


    <div class ="sidearm-schedule-game-details flex item-1 columns"> == $0
        <div class="sidearm-schedule-game-result text-italic"> == $0
            <span></span>
            <span>T,</span>
            <span>0-0</span>
            <span>(2 OT)</span>
        </div>



    import requests
    import pandas as pd
    from pandas import ExcelWriter
    from bs4 import BeautifulSoup


    url = 'https://lehighsports.com/sports/mens-soccer/schedule/2018'
    school = requests.get(url).text
    soup = BeautifulSoup(school,'lxml')

    rows = soup.find_all('div',class_="sidearm-schedule-game-row flex flex-wrap flex-align-center row")
        sheet = pd.DataFrame()
        for row in rows:
            result = row.find('div',class_="sidearm-schedule-game-result").text.strip()


            df = pd.DataFrame([[result]], columns=['result'])
            sheet = sheet.append(df,sort=True).reset_index(drop=True)

        results.append(sheet)

只是使用xpath，我会做这样的事情：

    a = html.xpath('//div[@class, "sidearm-schedule-game-result"]')
    #select all nodes that start with a <div> and have "sidearm-schedule-game-result" in the class.
    for each in a:
         b = each.xpath('.//span/text()')
         #the './/' will only look at subelements of what you selected earlier and text() will extract the text from that field.
         print(b)

我认为您正在寻找类似的东西：

import requests
import pandas as pd
from pandas import ExcelWriter
from bs4 import BeautifulSoup


url = 'https://lehighsports.com/sports/mens-soccer/schedule/2018'
school = requests.get(url).text
soup = BeautifulSoup(school,'lxml')

rows = soup.find_all('div',class_="sidearm-schedule-game-row flex flex-wrap flex-align-center row")

sheet = pd.DataFrame()
for row in rows:
    result = row.find('div',class_="sidearm-schedule-game-result").text.strip().replace('\n', ', ')
    df = pd.DataFrame([[result]], columns=['result'])
    sheet = sheet.append(df).reset_index(drop=True)

这将导致内容sheet如下所示：

           result
0          L, 1-2
1     L, 1-2 (OT)
2          W, 1-0
3          W, 1-0
4          L, 1-2
5   W, 1-0 (2 OT)
6   T, 0-0 (2 OT)
7          W, 3-0
8     L, 2-3 (OT)
9     W, 2-1 (OT)
10         W, 1-0
11         W, 1-0
12         L, 0-1
13  T, 0-0 (2 OT)
14         L, 0-1
15         W, 1-0
16         L, 0-1
17         W, 3-1
18         L, 1-2

您可以使用re模块解析<span>s 中的文本并将每个信息存储在单独的列Result, Score, OT.

例如：

import re
import requests
import pandas as pd
from bs4 import BeautifulSoup

url = 'https://lehighsports.com/sports/mens-soccer/schedule/2018'
school = requests.get(url).text
soup = BeautifulSoup(school,'lxml')

rows = soup.find_all('div',class_="sidearm-schedule-game-row flex flex-wrap flex-align-center row")

data = []
for row in rows:
    opponent = row.select_one('.sidearm-schedule-game-opponent-logo img')['alt'].rsplit(maxsplit=1)[0]
    name_date = row.select_one('.sidearm-schedule-game-opponent-name a')['aria-label']

    result = re.findall(r'([A-Z]),\s+([\d-]+)\s*(.*)', row.select_one('.sidearm-schedule-game-result').get_text(strip=True, separator=' '))[0]

    data.append([opponent, *result, name_date])

df = pd.DataFrame(data, columns=['Name', 'Result', 'Score', 'OT', 'Info'])
print(df)

印刷：
