如何遍历 HTML 并解析特定数据？-解网

问：

下面的 python 代码是从 html 特定数据中提取的，它仅适用于 html 中包含的一个实例。

我需要的是代码来遍历具有多个实例的 html 并检索特定信息。那么，我怎样才能做到这一点呢？

<!DOCTYPE html>
<html>
 <head>
  <meta charset="utf-8"/>
<title>Exported Data</title>
  <meta content="width=device-width, initial-scale=1.0" name="viewport"/>

python-3.x beautifulsoup html 解析

for b in soup.select('div[class="body"]'):
    d_str = b.select_one('div.date.details')['title']
    calendar = d_str.split(" ")
    print("Date: ",calendar[0])
    print("Time: ",calendar[1])
    targets = b.select('div.text')
    for target in targets:
        for sts in target.stripped_strings:
            if "⚽ Jogos: " in sts:   
                jugos = [elem for elem in sts.split('⚽ Jogos: ')[1].replace('( ',"(").split(" ") if elem]            
                if "✅" in jugos:
                    ind = jugos.index('✅')+1
                    print("Checkmarked: ", ind)
                    jugos.remove("✅")
                    print(jugos)
                else:
                    print(jugos)
                    print("Checkmarked: NA")
        print('------------------------------------')

输出：

Date:  09.03.2023
Time:  00:27:10
Checkmarked:  1
['03:30', '03:33', '03:36', '(03:39)']
------------------------------------
Date:  09.03.2023
Time:  00:45:16
Checkmarked:  1
['03:48', '03:51', '03:54', '(03:57)']
