本文實例講述了Python獲取任意xml節(jié)點值的方法。分享給大家供大家參考。具體實現(xiàn)方法如下：

				?

									# -*- coding: utf-8 -*-

									import xml.dom.minidom

									ELEMENT_NODE = xml.dom.Node.ELEMENT_NODE

									class 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
