如何在java中获取复杂嵌套xml的属性名称，值及其标记名称和值

Question

您好我有一个复杂的大型嵌套xml，我必须解析并插入数据库。 我使用JAVA X路径完成了它，但速度非常慢。

是否有任何方法可以获取所有属性名称和值，还可以标记以下xml的名称和值。 这是我的xml。 只需添加更多信息contentSet重复，儿童代码MentalSeriesStatements也会重复。

<evn:Body mVer="0.0" mjVe="1" contentSet="Mental">
<evn:Operation action="Edit">
<evn:Data si:type="al:MentalPeriodDataItem">

<al:MentalSeriesPeriod mentalSeriesPeriodIndex="33" mentalSeriesPeriodType="HalfYear" mentalSeriesPeriodEndDate="20000930T00:00:00+00:00">
