本文整理了Java中javax.xml.stream.XMLEventReader类的一些代码示例，展示了XMLEventReader类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。XMLEventReader类的具体详情如下：
包路径：javax.xml.stream.XMLEventReader
类名称：XMLEventReader

XMLEventReader介绍

[英]This is the top level interface for parsing XML Events. It provides the ability to peek at the next event and returns configuration information through the property interface.
[中]这是解析XML事件的顶级接口。它可以查看下一个事件，并通过属性接口返回配置信息。

代码示例
