所以我有一个<tr>带有多个<td>作为其子字符串的标签。
<tr>
<td align='center' class="row2">
<a href="javascript:who_posted(4713426);">10</a>
</td>
<td align="center" class="row2">
<a href='https://forum.net/index.php?;showuser=17311'>xxboxx</a>
</td>
<td align="center" class="row2">
<!--script type="text/javascript">
s = "236".replace(/,/g,'');
document.write(abbrNum(s,1));
</script-->
236
</td>
</tr>
这是我当前的代码；我没有问题，但是我想尝试退出脚本，但是我尝试了其他类似的关于stackoverflow的问题所提供的方法。但我没有成功。
def extractDataFromRow2(_url, 'td', 'row2', 'align' , 'center'):
try:
for container in _url.find_all('td', {'class': 'row2','align': 'center''}):
# get data from topic title in table cell
replies_numb = container.select_one(
'a[href^="javascript:]"').text
print('there are ' + replies_numb + ' replies')
topic_starter = container.next_sibling.text
print('the owner of this topic is ' + topic_starter)
for total_view in container.find('a', href=True, style=True):
#total_view = container.select_one(style="background-color:").text
#total_view = container.find(("td")["style"])
#total_view = container.next_sibling.find_next_sibling/next_sibling
#but they're not able to access the last one within <tr> tag
print(total_view )
if replies_numb and topic_starter is not None:
dict_replies = {'Replies' : replies_numb}
dict_topic_S = {'Topic_Starter' : topic_starter}
list_1.append(dict_replies)
list_2.append(dict_topic_S)
else:
print('no data')
except Exception as e:
print('Error.extractDataFromRow2:', e)
return None
是否有更清洁的方法；我很高兴从给出的反馈中学习。
您共享的html代码可能不足以回答问题，因此我签出了您共享的url。这是刮桌子的方法。
from bs4 import BeautifulSoup
import requests
r = requests.get("https://forum.lowyat.net/ReviewsandGuides")
soup = BeautifulSoup(r.text, 'lxml')
index = 0
#First two rows of table is not data so we skip it. Last row of table is for searching we also skip it. Table contains 30 rows of data. That is why we are slicing list
for row in soup.select('table[cellspacing="1"] > tr')[2:32]:
replies = row.select_one('td:nth-of-type(4)').text.strip()
topic_started = row.select_one('td:nth-of-type(5)').text.strip()
total_views = row.select_one('td:nth-of-type(6)').text.strip()
index +=1
print(index,replies, topic_started, total_views)
结果是
