我有一些 HTML，我試圖為其提取特定資訊，但是它有重復的元素，我知道如何解決這個問題。我正在嘗試實作如下條件引數：
- 從第一個
href標簽中提取玩家姓名 - 搜索下一個命名的標簽
flaggenrahmen并提取資料alt - 如果
flaggenrahmen再次重復，請跳過。 - 重復步驟。
我嘗試過的：
player_dict = defaultdict(list)
soup = BeautifulSoup(html)
player_id = soup.select('*[href]')
nation = soup.select('.flaggenrahmen')
for l,k in zip(player_id, nation):
player_dict[l.get_text(strip=True)].append(k['alt'])
但是，flaggenrahmen再次重復時我無法獲得“跳過” ，因此每個玩家可以獲得多個國家/地區。
產生的輸出：
defaultdict(list,
{'': ['England', 'Spain', 'Portugal'],
'Trent Alexander-Arnold': ['Morocco'],
'Achraf Hakimi': ['England']})
預期輸出：
{'Trent Alexander-Arnold':['England'],
'Achraf Hakimi':['Morocco'],
'Jo?o Cancelo':['Portugal'],
'Reece James':['England']
}
這是html資料：

uj5u.com熱心網友回復：
這應該做
players={}
soup = BeautifulSoup(html, 'lxml')
for el in soup.tbody.children:
if el.name!='tr':
continue
name=el.select_one('.spielprofil_tooltip')
country=el.select_one('.flaggenrahmen')
if name and country:
players[name.text]=[country['title']]
print(players)
>>> {'Trent Alexander-Arnold': ['England'], 'Achraf Hakimi': ['Morocco'], 'Jo?o Cancelo': ['Portugal'], 'Reece James': ['England']}
