将打开的xml文件parse为ElementTree对象。
可以通过ElementTree的 getiterator(tag)获得tree的tag节点元素Element列表。
可以通过节点元素Element的node.attrib获取属性字典等
如:
<vuln vuln-id="73863" vuln-name="Microsoft Windows TrueType远程代码执行漏洞(MS12-078)" vuln-severity="3" vuln-value="3"> <asset-IP>192.168.28.23</asset-IP> <asset-port>0</asset-port> <port-type>其他</port-type> <asset-protocol /> <asset-service /> <system-affected>Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, Windows 7 Gold and SP1, Windows 8, Windows Server 2012, and Windows RT</system-affected> - <remedy> <![CDATA[ 建议您采取以下措施进行修补以降低威胁: <br/> <br/>目前厂商已经发布了升级补丁以修复此安全问题,补丁获取链接: <br/> <br/><a href='http://technet.microsoft.com/zh-cn/security/bulletin/MS12-078' style='color:#0000fe;text-decoration:underline;' target='_blank'>http://technet.microsoft.com/zh-cn/security/bulletin/MS12-078</a> </remedy> - <description> <![CDATA[ 受影响的组件处理特制 TrueType 字体文件的方式中存在一个远程执行代码漏洞。如果用户打开特制的 TrueType 字体文件,该漏洞可能允许远程执行代码。 </description> - <cve cve-name="CVE-2012-4786" cve-status=""> - <cve-desc> <![CDATA[ The kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, Windows 7 Gold and SP1, Windows 8, Windows Server 2012, and Windows RT allow remote attackers to execute arbitrary code via a crafted TrueType Font (TTF) file, aka "TrueType Font Parsing Vulnerability." </cve-desc> </cve> <cncve>CNCVE-20124786</cncve> </vuln>
这个元素内含多个子元素,该元素<vuln>属性在头部括号内,通过节点attrib字段,可以访问属性字典。通过tag字段访问标记名称,通过text访问值,通过tail读末尾的文本(结束标记之后,下一开始标记或父元素标记结束之前)
还是以上面的xml为例子优雅的访问:
# -*-coding:utf-8 -*- __author__ = 'Administrator' class Vul: vul_name = '' ip = '' system_affect = '' desc = '' cveNo = '' cve_desc = '' cncve = '' def __init__(self, vul_name, ip, system_affect, desc, cveNo, cve_desc,cncve): self.vul_name = vul_name self.ip = ip self.system_affect = system_affect self.desc = desc self.cveNo = cveNo self.cve_desc = cve_desc self.cncve = cncve
# -*- encoding:utf-8 -*- __author__ = 'Administrator' from xml.etree import ElementTree import Vul import pprint with open('C:/XML/7.xml', 'rt') as f: tree = ElementTree.parse(f) # tree vul_list = tree.getiterator('vuln-list')[0] vuls = [] for vul in vul_list.iter(): # iter会遍历vullist每一个子项及子项的子项 if vul.tag == 'vuln': if vul.attrib: name = vul.attrib['vuln-name'] ip = vul.getiterator('asset-IP')[0].text sys_aff = vul.getiterator('system-affected')[0].text desc = vul.getiterator('description')[0].text cvedict = vul.getiterator('cve')[0].attrib cveNo = '' cve_desc = '' cncve = '' if cvedict.has_key('cve-name'): cveNo = cvedict['cve-name'] cve_desc = vul.getiterator('cve')[0].getiterator('cve-desc')[0].text if vul.getiterator('cncve'): cvcve = vul.getiterator('cncve')[0].text temp = Vul.Vul(name, ip, sys_aff, desc, cveNo, cve_desc, cncve) vuls.append(temp) for vul in vuls: print vul.vul_name,vul.cncve,vul.cveNo,vul.desc,vul
