我正在尝试使用 Python 获取由 html 中的外部脚本生成的文本：

<td class="headerlast item" rowspan="2" colspan="1" id="Party_ATP021_1">
<div id="Party_ATP021mod"></div>

<script type="text/javascript">
var myTooltip = new YAHOO.widget.Tooltip("Party_ATP021tip", { 
context:"Party_ATP021_1", text:"Sozialdemokratische Partei Österreichs 
(Social Democratic Party of Austria)", showDelay:1000, 
autodismissdelay:5000,iframe:true, preventoverlap:true } );
</script>
SPÖ
</td>

我试图得到：“SPÖ”没有成功。

到目前为止，我能够获得脚本中使用的 id：

import requests
from bs4 import BeautifulSoup
import re
from fake_useragent import UserAgent
ua = UserAgent()

link = 'http://eed.nsd.uib.no/webview/velocity?v=2&mode=cube&cube=http%3A%2F%2F129.177.90.166%3A80%2Fobj%2FfCube%2FSIEP2004%21Display_C1&study=http%3A%2F%2F129.177.90.166%3A80%2Fobj%2FfStudy%2FSIEP2004%21Display'

headers ={'user-agent': str(ua.random)}
result_page = BeautifulSoup(requests.get(link, headers=headers, 
timeout=10).text, 'html.parser')

for td in result_page.find_all('td', {'class': 'headerlast item'})[1:]:
    print(td.get('id'))

有什么帮助吗？非常感谢！

对于您的示例数据，您可以将select与 css 选择器一起使用，td.headerlast.item script并在 script 元素之后获取next_sibling。

html_doc = """
<td class="headerlast item" rowspan="2" colspan="1" id="Party_ATP021_1">
<div id="Party_ATP021mod"></div>

<script type="text/javascript">
var myTooltip = new YAHOO.widget.Tooltip("Party_ATP021tip", { 
context:"Party_ATP021_1", text:"Sozialdemokratische Partei Österreichs 
(Social Democratic Party of Austria)", showDelay:1000, 
autodismissdelay:5000,iframe:true, preventoverlap:true } );
</script>
SPÖ
</td>

"""

from bs4 import BeautifulSoup
result_page = BeautifulSoup(html_doc, 'html.parser')

for scrpt in result_page.select("td.headerlast.item script"):
    print(scrpt.next_sibling.strip())

这将导致：

SPÖ
