Java JSoup：提取文本并将其存储在多个变量中

我有以下情况：

我想提取“span”标记之间的所有文本

我希望它像这样存储：

A = 1,5,9,13
B = 2,6,10,14
C = 3,7,11,15
D = 4,8,12,16

请给我一些建议如何做到这一点。谢谢，节日快乐

编辑---------------------------------

我有一个想法：

if (exa != null) {
for (int i = 0; i < exa.size(); i++) {
A[i] = exa.get(0).text();
B[i] = exa.get(1).text();
C[i] = exa.get(2).text();
D[i] = exa.get(3).text();
      }
}

它重复前4个跨距

我怎样才能至少得到：

A = 1,2,3,4
B = 5,6,7,8
C = 9,10,11,12
D = 13,14,15,16

使用字符串

    public static void main(String... args) throws IOException {

        try {
            String text = "<div class=\"examplediv\"> <ul> <li><span>1</span></li> <li><span>2</span></li> <li><span>3</span></li> <li><span>4</span></li> </ul> </div> <div class=\"examplediv\"> <ul> <li><span>5</span></li> <li><span>6</span></li> <li><span>7</span></li> <li><span>8</span></li> </ul> </div> <div class=\"examplediv\"> <ul> <li><span>9</span></li> <li><span>10</span></li> <li><span>11</span></li> <li><span>12</span></li> </ul> </div> <div class=\"examplediv\"> <ul> <li><span>13</span></li> <li><span>14</span></li> <li><span>15</span></li> <li><span>16</span></li> </ul> </div>";
            String A = "", B = "", C = "", D = "";

            Document page = Jsoup.parse(text, "UTF-8");

            Elements uls = page.select(".examplediv ul");

            for(Element ul : uls) {
                Elements spans = ul.select("span");
                A += spans.get(0).text() + ",";
                B += spans.get(1).text() + ",";
                C += spans.get(2).text() + ",";
                D += spans.get(3).text() + ",";
            }

            A = A.substring(0, A.length() - 1);
            B = B.substring(0, B.length() - 1);
            C = C.substring(0, C.length() - 1);
            D = D.substring(0, D.length() - 1);

            System.out.println(A);
            System.out.println(B);
            System.out.println(C);
            System.out.println(D);
        } catch(Exception e) {
            e.printStackTrace();
        }
    }

使用StringBuilder

    public static void main(String... args) throws IOException {

        try {
            String text = "<div class=\"examplediv\"> <ul> <li><span>1</span></li> <li><span>2</span></li> <li><span>3</span></li> <li><span>4</span></li> </ul> </div> <div class=\"examplediv\"> <ul> <li><span>5</span></li> <li><span>6</span></li> <li><span>7</span></li> <li><span>8</span></li> </ul> </div> <div class=\"examplediv\"> <ul> <li><span>9</span></li> <li><span>10</span></li> <li><span>11</span></li> <li><span>12</span></li> </ul> </div> <div class=\"examplediv\"> <ul> <li><span>13</span></li> <li><span>14</span></li> <li><span>15</span></li> <li><span>16</span></li> </ul> </div>";
            StringBuilder A = new StringBuilder(), B = new StringBuilder(), C = new StringBuilder(), D = new StringBuilder();

            Document page = Jsoup.parse(text, "UTF-8");

            Elements uls = page.select(".examplediv ul");

            for(Element ul : uls) {
                Elements spans = ul.select("span");
                A.append(spans.get(0).text() + ",");
                B.append(spans.get(1).text() + ",");
                C.append(spans.get(2).text() + ",");
                D.append(spans.get(3).text() + ",");
            }

            A.deleteCharAt(A.length() - 1);
            B.deleteCharAt(B.length() - 1);
            C.deleteCharAt(C.length() - 1);
            D.deleteCharAt(D.length() - 1);

            System.out.println(A);
            System.out.println(B);

这种行为的原因是因为您使用了=而不是+=所以您覆盖了以前的值。 也许这就是你想要的

public static void main(String... args) throws IOException {

    try {
        String text = "<div class=\"examplediv\"> <ul> <li><span>1</span></li> <li><span>2</span></li> <li><span>3</span></li> <li><span>4</span></li> </ul> </div> <div class=\"examplediv\"> <ul> <li><span>5</span></li> <li><span>6</span></li> <li><span>7</span></li> <li><span>8</span></li> </ul> </div> <div class=\"examplediv\"> <ul> <li><span>9</span></li> <li><span>10</span></li> <li><span>11</span></li> <li><span>12</span></li> </ul> </div> <div class=\"examplediv\"> <ul> <li><span>13</span></li> <li><span>14</span></li> <li><span>15</span></li> <li><span>16</span></li> </ul> </div>";
        ArrayList<String> A = new ArrayList<String>(), B = new ArrayList<String>(), C = new ArrayList<String>(), D = new ArrayList<String>();

        Document page = Jsoup.parse(text, "UTF-8");

        Elements uls = page.select(".examplediv ul");

        for(Element ul : uls) {
            Elements lis = ul.select("span");
            A.add(lis.get(0).text());
            B.add(lis.get(1).text());
            C.add(lis.get(2).text());
            D.add(lis.get(3).text());
        }

        for(String str : A) {

嗯？也许你可以详细说明一下？我提供的代码与你描述的完全一样。那么，问题出在哪里呢？检查新的部分。你没有说你想要数组。检查我的更新。等等。你所做的毫无意义。exa大小是您的跨距数。你所做的是完全错误的。

A = 1,2,3,4
B = 5,6,7,8
C = 9,10,11,12
