Python is used to obtain any xml node value. python is used to obtain xml nodes.

This example describes how to obtain the value of any xml node using Python. 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.
