第一种方法:python操作xml文件

随手找了一个xml文件内容(jenkins相关文件)

	The Headers filter allows us to override headers sent by the container
	that may be in conflict with what we want.  For example, Tomcat will set
	Cache-Control: no-cache for any files behind the security-constraint
	below.  So if Hudson is on a public server, and you want to only allow
	authorized users to access it, you may want to pay attention to this.
