Python3使用xml.dom.minidom和xml.etree模块儿解析xml文件封装函数的方法

总结了一下使用Python对xml文件的解析，用到的模块儿如下：

分别从xml字符串和xml文件转换为xml对象，然后解析xml内容，查询指定信息字段。

from xml.dom.minidom import parse, parseString
from xml.etree import ElementTree
import xml.dom.minidom
"""
Get XML String info 查询属性值
 response:xml string
 tag:xml tag
 element:xml attribute
"""
def get_xml_info(response, element):
 DOMTree = xml.dom.minidom.parseString(response)
 return DOMTree.documentElement.getAttribute(element)
"""
Get XML String info 查询制定名称的特定标签id
 xmlstring:xml str
 return config id
"""
def get_config_id_from_xml(xmlstring, scan):
 root = ElementTree.fromstring(xmlstring)
 configs = root.findall('config')
 for config in configs:
   config_name = config.find('name').text
   if config_name == scan:
     return config.attrib['id']
"""
Get XML String info 查询指定id
 xmlstring:xml str
 return report id
"""
def get_report_id_from_xml(xmlstring):
 root = ElementTree.fromstring(xmlstring)
 report_id = root.find('report_id').text
 return report_id
"""
Get XML String info
 xmlstring:xml str
 return progress
"""
def get_progress_from_xml(xmlstring):
 root = ElementTree.fromstring(xmlstring)
 task = root.find('task')
 progress = float(task.find('progress').text)
 if progress < 0:
   return 100.0
 else:
   return progress
"""
Get XML Report info 从xml文件查询
 file_path : report path
"""
def get_xml_report(file_path):
 report = {}
 result_dicts = {}
 resultsList = []
 try:
   root = ElementTree.parse(file_path)
 except:
   return {}
 if root is not None:
   creation_time = root.find("creation_time")
   if creation_time is not None:
     report[creation_time.tag] = creation_time.text
   if root.find("report") is not None:
     scan_start = root.find("report").find("scan_start")
     if scan_start is not None:
       if scan_start.text:
         report[scan_start.tag] = scan_start.text
   results = root.getiterator("result")
   if results is not None:
     for result in results:
       if result.find("threat") is not None:
         if result.find("threat").text != "Log":
           resultsList.append(getResults(result))
 report["Results"] = resultsList
 return report
