我有一个网页,其中有很多行的表格。用户会给我一个数字(15308),该数字可以在顶行找到并且带有第一个<td>
标签,这是我唯一的信息。我希望能够使用此数字在<th></th>
标记(更具体地说是0)之间查找数据,但仅用于表行。例如,我附加了两个表行,并且我希望使用数字15308来存储<th>
数据,而不是在其第一个<th>
中具有数字15309的表行中的<td>
数据。感谢您的帮助!
期望的输出:0

使用以下代码:
userValue='15308'
all_td_th_of_row = driver.find_elements_by_xpath("//td[normalize-space()='" + userValue + "']//following-sibling::td|th")
i = 0
while i<len(all_td_th_of_row) :
print(all_td_th_of_row[i].text)
i=i+1

使用beauitfulsoup
,我一直发现自己很美:
使用 xpath="1"
作为属性:
line = '''<tr><td><a href="http://sdb.admin.uw.edu/timeschd/UWNetID/sln.asp?QTRYR=SPR+2019&SLN=15308" style="">15308</a></td>
<td nowrap="">INFO 101 </td>
<td>A </td>
<td align="CENTER">LC</td>
<td>SOCIAL NETWORKING </td>
<td align="CENTER"> 150</td>
<td align="CENTER"> 150</td>
<td align="CENTER"> 250</td>
<th align="CENTER" style="" xpath="1"> 0</th><td align="CENTER"> 229</td>
<td></td>
</tr>'''
from bs4 import BeautifulSoup
soup = BeautifulSoup(line, 'html.parser')
xpathTh = soup.find('th', attrs={'xpath': '1'})
print(xpathTh.text.strip())
输出:

要从属性中获取所有值:
line = '''<tr><td><a href="http://sdb.admin.uw.edu/timeschd/UWNetID/sln.asp?QTRYR=SPR+2019&SLN=15308" style="">15308</a></td>

<td align="CENTER"> 150</td>
<td align="CENTER"> 250</td>
<th align="CENTER" style="" xpath="1"> 0</th><td align="CENTER"> 229</td>
<th align="CENTER" style="" xpath="1"> 1</th><td align="CENTER"> 229</td>
<th align="CENTER" style="" xpath="1"> 2</th><td align="CENTER"> 229</td>

xpathTh = soup.find_all('th', attrs={'xpath': '1'})
for elem in xpathTh:

考虑到您仅希望xpath value
内部(anchor tag
内部的td
的值为tr
的{{1}}:
15308
