本文整理了Java中org.apache.felix.ipojo.metadata.Element类的一些代码示例，展示了Element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。Element类的具体详情如下：
包路径：org.apache.felix.ipojo.metadata.Element
类名称：Element

Element介绍

[英]An element represents an XML Element. It contains a name, a namepace, Attribute objects and sub-elements. This class is used to parse iPOJO metadata.
[中]元素表示XML元素。它包含名称、名称空间、属性对象和子元素。此类用于解析iPOJO元数据。
