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()
