使用 JSoup 从 div 中获取第二个单词

Question

我的代码我得到了div中的所有单词。我需要做什么才能只获取 div 中的第二个单词？

例如：

<div id="div01"> FIRSTWORD SECONDWORD </DIV>

我的代码：

Document doc = Jsoup.connect(url).get();

Elements statistics = doc.select(div.div01);

textDiv1 = statistics.text();

Answer 1

为什么不像 Java 字符串中的第二个单词那样呢？

String secondWord = line.split(" ")[1]; //add your own checks to avoid out of bounds or null exceptions.

扩展现有内容的示例：

if (textDiv1 != null) {
    String[] words = textDiv1.split(" ");   //split our text into individual words, which are separated by spaces
    if (words.length >= 2) {                //there are at least two words
        String secondWord = words[1];
    }
    //otherwise, there is no second word, so you can handle it here
}
//there is no text found as textDiv1 is null

** 除非你的第二个词恰好在它自己的元素中，否则这不是 JSOUP 会区分的东西 **

@AllanW 最后一个代码是示例代码..这是我的真实代码：

private class Div1 extends AsyncTask<String, String, String> {
        String text = null;
        String text2 = null;

        @Override
        protected void onPreExecute() {
            super.onPreExecute();

        }

        @Override
        protected String doInBackground(String... params) {

            try {
                // Connect to the web site
                Document doc = Jsoup.connect(url).get();

                // Using Elements to get the Meta data
                Elements statistics = doc.select("div.statistics__userInfo > div");

                if (text !=null){

                    String[] words = text.split("");
                    if (words.length >= 2) {
                        String secondWord = words[1];
                    }
                }
                Elements span1 = doc.getElementsByTag("span");
                doc.getElementsByTag("span").remove();
                // Locate the content attribute
                text = statistics.text();
                text2 = span1.text();

            } catch (IOException e) {
                e.printStackTrace();
            }
            return text;
        }
