如何在jsoup中获取元素的一级子级

Element.children（）仅返回直接子代。由于您将它们绑定到树上，因此它们也有孩子。

如果需要直接子元素而没有底层树结构，则需要按以下方式创建它们

public static void main(String... args) {    document document = Jsoup .parse("<div><ul><li>11</li><li>22</li></ul><p>ppp<span>sp</span</p></div>");    Element div = document.select("div").first();    Elements divChildren = div.children();    Elements detachedDivChildren = new Elements();    for (Element elem : divChildren) {        Element detachedChild = new Element(Tag.valueOf(elem.tagName()),     elem.baseUri(), elem.attributes().clone());        detachedDivChildren.add(detachedChild);    }    System.out.println(divChildren.size());    for (Element elem : divChildren) {        System.out.println(elem.tagName());    }    System.out.println("ndivChildren content: n" + divChildren);    System.out.println("ndetachedDivChildren content: n" + detachedDivChildren);}

输出量

2ulpdivChildren content: <ul> <li>11</li> <li>22</li></ul><p>ppp<span>sp</span></p>detachedDivChildren content: <ul></ul><p></p>
