如何从一组元素中删除元素？

Question

鉴于以下代码:

HTML:

<div>a</div>
<div>b</div>
<div>c</div>

JS:

Document doc = Jsoup.parse(baseHtml);
Elements elements = doc.select("div");
elements.get(1).remove();
// remove doesn't affect elements. why?
elements.size();   // equal 3
// but this works
doc.outerHtml() // <div>a</div><div>c</div>

我是否必须使用此代码来删除元素？这似乎太冗长了.

Document doc = Jsoup.parse(baseHtml);
Elements elements = doc.select("div");
elements.get(1).remove();
elements = doc.select("div");

这应该可以帮到你:

public class TestJsoup {

    public static void main(String[] args) {
        try {
            Document doc = Jsoup.connect("http://www.google.ro").get();
            Elements select = doc.select("div");
            System.out.println(select.size());
            select.remove(1);
            System.out.println(select.size());
        } catch (IOException ex) {
            Logger.getLogger(TestJsoup.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
}
