问题描述

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

2
ul
p

divChildren content: 
<ul>
 <li>11</li>
 <li>22</li>
</ul>
<p>ppp<span>sp</span></p>

detachedDivChildren content: 
<ul></ul>
<p></p>
