刪除特定的項目Python Beautiful Soup

Question

我該如何將其去除，並使用python和漂亮的湯把剩下的剩下， td其他項目需要保留

<td style="background:#aaccff" width="50"></td>
<td align="left" style="background:#aaccff" width="150">Device Type</td>
<td align="left" style="background:#aaccff" width="115">IP Address</td>
<td align="left" style="background:#aaccff" width="100">Device Name</td>
<td align="left" style="background:#aaccff" width="215">Notes</td>
<td width="50"></td>

這是完整的代碼

<td style="background:#aaccff" width="50"></td>
<td align="left" style="background:#aaccff" width="150">Device Type</td>
<td align="left" style="background:#aaccff" width="115">IP Address</td>
<td align="left" style="background:#aaccff" width="100">Device Name</td>
<td align="left" style="background:#aaccff" width="215">Notes</td>
<td width="50"></td>
<td align="left" width="150">AudioCodes Gateway</td>
<td align="left" width="115">172.31.31.2</td>

<td align="left" style="background:#aaccff" width="100">Device Name</td>
<td align="left" style="background:#aaccff" width="215">Notes</td>
<td width="50"></td>

<td align="left" width="215">NAT'd IP = PENDING MPLS, Voice IP = 172.31.52.151</td>
<td width="50"></td>
<td align="left" width="150">IC Server</td>
<td align="left" width="115">172.31.56.152</td>
<td align="left" width="100">IND056GIC152</td>
<td align="left" width="215">NAT'd IP = PENDING MPLS, Voice IP = 172.31.52.152</td>
<td width="50"></td>

<td align="left" width="115">IND1106HMS07</td>
<td align="left" width="100">IND1106HMS07</td>
<td align="left" width="215"></td>

這是到目前為止我有代碼明智

from ntlm import HTTPNtlmAuthHandler
from bs4 import BeautifulSoup
import requests, os, bleach, urllib2, cookielib

os.system('clear')
user = 'user'
password = "pass"
url = "url"

cookies = cookielib.CookieJar()
passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
passman.add_password(None, url, user, password)
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookies),HTTPNtlmAuthHandler.HTTPNtlmAuthHandler(passman))

pagedata=opener.open(url)
soup=BeautifulSoup(pagedata)

def myfunction(b):
table = b.find('ul', {'class': 'dfwp-column dfwp-list'})

for a in table.findAll('a'):
    [a.decompose() for a in table("a")]
for tr in table.findAll('tr'):
    for td in tr.findAll('td'):

        print td

myfunction(soup)

這是當前的輸出

Answer 1

通常，當人們問如何使用bs4 “刪除”某些東西時，他們實際上只是在問如何不在find操作中包括它。

您要排除多余的空格（即帶有tag.text == ''標簽）和這四個“列標題”標簽。 您可以通過CSS選擇器來完成后者，但是前者需要明確過濾。 因此，一次執行這兩項操作最簡單，而且在我看來更具聲明性：

soup = BeautifulSoup(that_long_html_you_gave)

blacklist = {'Device Type','IP Address','Device Name','Notes'}

table = soup.body # to match your variable name.  I think.

table.find_all(lambda tag: tag.text and tag.text not in blacklist)
