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
