本文整理了Java中org.jdom.Element.getChildren()方法的一些代码示例，展示了Element.getChildren()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.getChildren()方法的具体详情如下：
包路径：org.jdom.Element
类名称：Element
方法名：getChildren

Element.getChildren介绍

[英]This returns a List of all the child elements nested directly (one level deep) within this element, as Element objects. If this target element has no nested elements, an empty List is returned. The returned list is "live" in document order and changes to it affect the element's actual contents.

Sequential traversal through the List is best done with a Iterator since the underlying implement of List.size() may not be the most efficient.

No recursion is performed, so elements nested two levels deep would have to be obtained with:

Iterator itr = (currentElement.getChildren()).iterator(); 
while(itr.hasNext()) { 
Element oneLevelDeep = (Element)itr.next(); 
List twoLevelsDeep = oneLevelDeep.getChildren(); 
// Do something with these children 
}

[中]这将返回直接嵌套在该元素中的所有子元素的List，作为Element对象。如果此目标元素没有嵌套元素，则返回空列表。返回的列表在文档顺序中是“活动”的，对它的更改会影响元素的实际内容。
通过列表的顺序遍历最好使用迭代器完成，因为列表的底层实现是这样的。size（）可能不是最有效的。
不执行递归，因此嵌套在两层深处的元素必须通过以下方式获得：

Iterator itr = (currentElement.getChildren()).iterator(); 
while(itr.hasNext()) { 
Element oneLevelDeep = (Element)itr.next(); 
List twoLevelsDeep = oneLevelDeep.getChildren(); 
// Do something with these children 
}
