话部多说，xml格式如下：
<?xml version="1.0" encoding="UTF-8"?> <conf> <nova>192.168.0.1</nova> <glance>192.168.0.2</glance> <keystone>192.168.0.3</keystone> </conf>
conf文件如下：
[service_ip_list] keystone = X.X.X.X nova = X glance = X
需要提取xml中的属性和值替换掉conf中的对应的配置，转换程序是用python写的
#-*-coding:utf-8-*-
from xml.dom import minidom
doc = minidom.parse("conf.xml")
conf_elements=doc.getElementsByTagName("conf")[0]
nova=conf_elements.getElementsByTagName("nova")[0]
#print nova.nodeName,nova.childNodes[0].nodeValue
glance=conf_elements.getElementsByTagName("glance")[0]
#print glance.nodeName,glance.childNodes[0].nodeValue
keystone=conf_elements.getElementsByTagName("keystone")[0]
#keystone_ip=keystone.childNodes[0].nodeValue
#print keystone.nodeName,keystone.childNodes[0].nodeValue
import ConfigParser
import string,os,sys
cf=ConfigParser.ConfigParser()
cf.read("ip-list.conf")
cf.set("service_ip_list","keystone",keystone.childNodes[0].nodeValue)
cf.set("service_ip_list","nova",nova.childNodes[0].nodeValue)
cf.set("service_ip_list","glance",glance.childNodes[0].nodeValue)
fh=open("ip-list.conf",'w')
cf.write(fh)
fh.close() 原文链接：https://www.f2er.com/xml/299018.html
