从xml中使用python bs4和lxml提取值

如何从下面的xml文件中提取听众的数量<listeners>10</listeners>，我的代码不工作。从xml中使用python bs4和lxml提取值

import bs4 
import urllib2 
import lxml 
bs4.BeautifulSoup(urllib2.urlopen('http://admin:[email protected]:8382/admin/').read(), 'lxml')  
SERVER = 'http://192.168.0.31:8382/admin/' 
authinfo = urllib2.HTTPPasswordMgrWithDefaultRealm() 
authinfo.add_password(None, SERVER, 'admin', 'mypassword') 
page = 'http://192.168.0.31:8382/admin/' 
handler = urllib2.HTTPBasicAuthHandler(authinfo) 
myopener = urllib2.build_opener(handler) 
opened = urllib2.install_opener(myopener) 
output = urllib2.urlopen(page) 
print output.read() 
soup = bs4.BeautifulSoup(output.read(), 'lxml') 
print soup.find('listeners')

和XML是如下

使用本：

soup = BeautifulSoup(output.read()) 
soup.select('listeners') 
[<listeners>10</listeners>, <listeners>0</listeners>]

我得到的是[]？ – Ossama

请检查你的汤对象，它是否包含任何数据？因为这应该工作 –

使用打印output.read（）在上面的代码打印xml文件 – Ossama

试试这个：

soup = BeautifulSoup(output.read(), 'xml') 
for value in soup.find_all('listeners'): 
    print(value.get_text())

这将如何与多个'listeners'项目一起工作？你能扩展你的代码吗？ – Risadinha

对不起，当然你需要使用find_all。像这样：'soup = BeautifulSoup（page，'xml'） for soup.find_all（'listeners'）： print（value.get_text（））' – komito

我更正了我的答案 – komito

从xml中使用python bs4和lxml提取值
