Python解析NMAP XML输出“elem key =”NodeList

Question

我想解析NMAP XML文件中的特定值。 xml文件的部分看起来像这样：

<nmaprun scanner="nmap" args="nmap -A -P0 -oA scanoutput 192.168.1.5" start="1445258532" startstr="Mon Oct 19 08:42:12 2015" version="6.47" xmloutputversion="1.04"> 
    <hostscript> 
     <script id="smb-os-discovery" output="&#10; OS: Windows Server 2008 R2 Standard 7601 Service Pack 1 (Windows Server 2008 R2 Standard 6.1)&#10; OS CPE: cpe:/o:microsoft:windows_server_2008::sp1&#10; Computer name: SOMEHOSTNAME&#10; NetBIOS computer name: SOMEHOSTNAME&#10; Domain name: domain.local&#10; Forest name: domain.local&#10; FQDN: SOMEHOSTNAME.domain.local&#10; System time: 2015-10-19T08:50:07-04:00&#10;"> 
      <elem key="os">Windows Server 2008 R2 Standard 7601 Service Pack 1</elem> 
      <elem key="lanmanager">Windows Server 2008 R2 Standard 6.1</elem> 
      <elem key="server">SOMEHOSTNAME\x00</elem> 
      <elem key="date">2015-10-19T08:50:07-04:00</elem> 
      <elem key="fqdn">SOMEHOSTNAME.domain.local</elem> 
      <elem key="domain_dns">domain.local</elem> 
      <elem key="forest_dns">domain.local</elem> 
      <elem key="workgroup">HOME\x00</elem> 
      <elem key="cpe">cpe:/o:microsoft:windows_server_2008::sp1</elem> 
     </script> 
    </hostscript> 
</nmaprun> 

我想从每个键的值，但不知道如何解决它。例如，如何从得到的值elem key =“os”？到目前为止，我可以得到完整的输出，但是当我将它添加到CSV中时，它会变得杂乱，我需要分别将每个值分开。下面是我的代码有：

serveros = [script.getAttribute('output') for script in hosttag.getElementsByTagName('script') if script.getAttribute('id') == 'smb-os-discovery'] 

如果我将其更改为：

serveros = [script.getElementsByTagName('os') for script in hosttag.getElementsByTagName('script') if script.getAttribute('id') == 'smb-os-discovery'] 

我得到这个错误：

TypeError: sequence item 0: expected string, NodeList found 

提前感谢！

也许是这样的：

class ScriptResult: 
    def __init__(self, script, port_number): 
     self.port_number = port_number 
     for k,v in script.attrib.iteritems(): 
      self.__dict__[k] = v 
     return 

    def __str__(self): 
     d = '\n' 
     for k,v in self.__dict__.iteritems(): 
      d += ' %-30s : %s\n' % (k,v) 
     return "ScriptResult(%s)\n" % d 

class Host: 
    def __init__(self): 
     self.script_results = [] # define list of script results 
     return 

    def print_results(self): 
     for i in self.script_results: 
      print i 
     return 


class XML_Parser: 

    def get_hostscripts(self, host, xml_host_element): 
     for hs in xml_host_element.findall('hostscript'): 
      for s in hs.findall('script'): 
       host.script_results.append(ScriptResult(s, 'host'))
