如何使用python

您好我有这样的XML，我想获得与名称和每个分支元素类型和FullProductName字符串元素（“思科统一计算系统（相关字符串解析有相同的名字元素的XML数据管理软件）3.0（1）c“）。我试图用python使用bs4来做到这一点。但我不知道我该怎么做。如何使用python

    <Note Title="Summary" Type="General" Ordinal="1">A vulnerability in the web-based GUI of Cisco Integrated Management Controller (IMC) could allow an unauthenticated, remote attacker to perform unauthorized remote command execution on the affected device. 

The vulnerability exists because the affected software does not sufficiently sanitize specific values that are received as part of a user-supplied HTTP request. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected software. Successful exploitation could allow an unauthenticated attacker to execute system commands with root-level privileges. 

There are no workarounds that address this vulnerability.

的Python：

from bs4 import BeautifulSoup 

xmlData = open("test.xml") 
soup = BeautifulSoup(xmlData, "lxml") 
preoductTree = soup.producttree 

vendor = preoductTree.find_all("branch", attrs={"type": "Vendor"})

任何想法？

预先感谢您。

所以，你必须先找到标签，所以我们可以通过文件迭代。我将要使用固有的python xml包。

import xml.etree.ElementTree as ET 
tree = ET.parse('test.xml') 
root = tree.getroot()

然后让我们找到第一个子标签，以便我们可以运行该文件。

for child in root: 
    print child.tag, child.attrib 

>>{http://www.icasi.org/CVRF/schema/prod/1.1}Branch, {'Type': 'Vendor', 'Name': 'Cisco'}

因此，您可以看到它不仅仅是您指定的branch。现在

我们可以通过整个文件递归运行，并抓住所有这些元素。既然你没有指定所需的输出结构，我会把它放在你的字典中。

val_dict = dict() 
for schild in root.iter('{http://www.icasi.org/CVRF/schema/prod/1.1}Branch'): 
     val = schild.attrib 
     val_dict[val.get('Type')] = val.get('Name') 

>>{'Product Name': 'Cisco Unified Computing System (Management Software)', 
'Product Version': '3.0', 
'Service Pack': '(1)c', 
'Vendor': 'Cisco'}

谢谢你的回答，对不起，但我错了xml的结构。 –

我觉得是一样的，你没有，但accesing到ProductTree为根，我怎么没有我可以访问ProductTree为根。 –

编辑，代码只是稍作修改。如果你浏览'xml'文档，这对你来说是一个快速的解决方案。 –
