由上一遍的准备工作完成后，可以很简单的就进行对xml文件的操作，

以上代码除了删除的以外都可以运行出来，唯独删除，出错，报了以下异常：
Exception in thread "main" org.apache.xmlbeans.impl.values.XmlValueNotNillableException
at org.apache.xmlbeans.impl.values.XmlObjectBase.setNil(XmlObjectBase.java:624)
at com.CustomerXMLBean.deleteCustomer(CustomerXMLBean.java:167)
at com.CustomerXMLBean.main(CustomerXMLBean.java:187)
经过我反编译通过上篇使用scomp生成的jar包，发现接口中定义的setNil（）方法并没有被实现重写，暂时没有想出问题出在哪，或许可能因为使用的xmlBean的版本太低导致，假如有读者也遇到问题，可以联系我，讨论一下，找出解决方法。
