我想使用 beautiful soup 解析一個(gè) HTML 文檔，其中也包含表格數(shù)據(jù)。我正在對(duì)此做一些 NLP。表格單元格可能只有數(shù)字，也可能有大量文本。因此，在執(zhí)行 soup.get_text() 之前，我希望根據(jù)以下條件更改表格數(shù)據(jù)的內(nèi)容。條件：如果單元格有兩個(gè)以上的單詞（我們可以認(rèn)為一個(gè)數(shù)字是一個(gè)單詞），則只保留它，否則將單元格內(nèi)容更改為空字符串。<code to change table data based on condition>soup = BeautifulSoup(html)text = soup.get_text()這是我嘗試過(guò)的。 tables = soup.find_all('table') for table in tables: table_body = table.find('tbody') rows = table_body.find_all('tr') for row in rows: cols = row.find_all('td') for ele in cols: if len(ele.text.split(' ')<3): ele.text = ''但是，我們無(wú)法設(shè)置 ele.text，因此它會(huì)引發(fā)錯(cuò)誤。這是一個(gè)帶有表格的簡(jiǎn)單 HTML 結(jié)構(gòu)<!DOCTYPE html><html> <head> <title>HTML Tables</title> </head> <body> <table border = "1"> <tr> <td><p><span>Row 1, Column 1, This should be kept because it has more than two tokens</span></p></td> <td><p><span>not kept</span></p></td> </tr> <tr> <td><p><span>Row 2, Column 1, should be kept</span></p></td> <td><p><span>Row 2, Column 2, should be kept</span></p></td> </tr> </table> </body></html>

一旦找到該元素，然后使用ele.string.replace_with("")
基于您的示例 html
html='''<html>
<head>
<title>HTML Tables</title>
</head>
<body>
<table border = "1">
<tr>
<td><p><span>Row 1, Column 1, This should be kept because it has more than two tokens</span></p></td>
<td><p><span>not kept</span></p></td>
</tr>
<tr>
<td><p><span>Row 2, Column 1, should be kept</span></p></td>
<td><p><span>Row 2, Column 2, should be kept</span></p></td>
</tr>
</table>
</body>
</html>'''
soup=BeautifulSoup(html,'html.parser')
tables = soup.find_all('table')
for table in tables:
rows = table.find_all('tr')
for row in rows:
cols = row.find_all('td')
for ele in cols:
if len(ele.text.split(' '))<3:
ele.string.replace_with("")
print(soup)
輸出：
<html>
<head>
<title>HTML Tables</title>
</head>
<body>
<table border="1">
<tr>
<td><p><span>Row 1, Column 1, This should be kept because it has more than two tokens</span></p></td>
<td><p><span></span></p></td>
</tr>
<tr>
<td><p><span>Row 2, Column 1, should be kept</span></p></td>
<td><p><span>Row 2, Column 2, should be kept</span></p></td>
</tr>
</table>
</body>
</html>
