How to obtain any xml node value using Python

This article describes how to obtain the value of any xml node by using Python. It involves some skills related to operating XML nodes by using Python and has some reference value, for more information about how to obtain the value of any xml node in Python, see the following example. Share it with you for your reference. The specific implementation method is as follows:

# -*- coding: utf-8 -*-import xml.dom.minidomELEMENT_NODE = xml.dom.Node.ELEMENT_NODEclass SimpleXmlGetter(object):  def __init__(self, data):    if type(data) == str:      self.root = xml.dom.minidom.parse(data)    else:      self.root = data  def __getattr__(self, name):    #support . operation    if name == 'data':      return self.root.firstChild.data    for c in self.root.childNodes:      if c.nodeType == ELEMENT_NODE and c.tagName == name:        return SimpleXmlGetter(c)  def __getitem__(self, index):    #support [] operation    eNodes = [ e for e in self.root.parentNode.childNodes          if e.nodeType == ELEMENT_NODE and e.tagName == self.root.tagName]    return SimpleXmlGetter(eNodes[index])  def __call__(self, *args, **kwargs): #support () openration, for query conditions    for e in self.root.parentNode.childNodes:      if e.nodeType == ELEMENT_NODE:        for key in kwargs.keys():           if e.getAttribute(key) != kwargs[key]:            break        else:          return SimpleXmlGetter(e)if __name__ == "__main__":  x = SimpleXmlGetter("sysd.xml")  print x.sysd.sysagent.param[2].data  print x.sysd.sysagent.param(name="querytimeout", type="second").data

I hope this article will help you with Python programming.
