如何用BeautifulSoup遍历tr元素抓取复杂体育博彩表格数据

需求说明 #

需从指定HTML表格中提取以下信息：

• 赛事时间、日期
• 两位参与者姓名
• 额外市场数量（+4）
• 对应赔率
• 参与者上方的赛事链接

表格典型HTML结构：

<tr data-qa="pre-event" class="events-list__grid__event"><th scope="row" class="events-list__grid__info"><div class="events-list__grid__info__datetime"><div class="events-list__grid__info__datetime__time">
            20:05
          </div> <div class="events-list__grid__info__datetime__date">
            24/07
          </div></div> <a href="/cote/sara-errani-paula-ormaechea/27034463/" class="GTM-event-link events-list__grid__info__main" data-testid="TENN" title="WTA - Varșovia - Calificări (F)"><div class="events-list__grid__info__main__row"><div class="events-list__grid__info__main__participants"><div class="events-list__grid__info__main__participants__participant"><span class="events-list__grid__info__main__participants__participant-name"><!---->

提取实现（Python + BeautifulSoup） #

遍历所有目标行，精准定位元素提取数据：

from bs4 import BeautifulSoup

# 假设html_content为获取到的页面HTML内容
soup = BeautifulSoup(html_content, 'html.parser')

# 遍历所有赛事行
for event_row in soup.select('tr[data-qa="pre-event"]'):
    # 提取时间、日期
    event_time = event_row.select_one('.events-list__grid__info__datetime__time').get_text(strip=True)
    event_date = event_row.select_one('.events-list__grid__info__datetime__date').get_text(strip=True)
    
    # 提取赛事链接
    event_link = event_row.select_one('.events-list__grid__info__main')['href']
    
    # 提取参与者姓名
    participant_names = [
        p.get_text(strip=True)
        for p in event_row.select('.events-list__grid__info__main__participants__participant-name')
    ]
    
    # 提取额外市场数
    market_count = event_row.select_one('.table__markets__market__title__markets__link').get_text(strip=True)
    
    # 提取赔率
    odds_values = [
        o.get_text(strip=True)
        for o in event_row.select('.selections__selection__odd')
    ]
    
    # 整理结果
    event_data = {
        '时间': event_time,
        '日期': event_date,
        '参与者': participant_names,
        '赛事链接': event_link,
        '额外市场数': market_count,
        '赔率': odds_values
    }
    
    print(event_data)

关键说明 #

• 用tr[data-qa="pre-event"]定位所有赛事行，避免无关数据干扰
• 通过类名逐层定位子元素，get_text(strip=True)自动去除文本中的空格、换行
• 若需兼容元素缺失场景，可给每个提取步骤添加空值判断（如elem.get_text(...) if elem else None）
