Salary and Benefits 5
Job Security 5
Career Growth 4
Work Environment 5
CEO Rating 5

请帮助我获取格式提前谢谢你

Answer 1

如果要计算的“标记”字符串是静态的（或至少是“预定义”），您可以执行以下操作，使用Apache commons-lang：

String str = "Salary and Benefits <span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span>";
String spanText = "<span class=\"read-barfull\"></span>";
int count = StringUtils.countMatches(str, spanText);

Answer 2

以下是使用Jsoup的方法（因为您的问题已被标记）。一般的想法是

逐行阅读HTML
获取此HTML行所代表的文字
选择所有<span class="read-barfull"></span>元素（无论它们是否为空，但您可以根据需要进行更改） - 简单select("span.read-barfull")将为我们执行此操作
所选span元素的打印计数（此处size()非常有用）

代码：

String html = "Salary and Benefits <span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span>\r\n" + 
        "Job Security <span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span>\r\n" + 
        "Career Growth <span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barnone\"></span>\r\n" + 
        "Work Environment <span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span>\r\n" + 
        "CEO Rating <span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span><span class=\"read-barfull\"></span>";

Scanner sc = new Scanner(html);
while(sc.hasNextLine()){
    Document doc = Jsoup.parse(sc.nextLine());
    System.out.println(doc.text()+" "+doc.select("span.read-barfull").size());
}

输出：

Salary and Benefits 5
Job Security 5
Career Growth 4
Work Environment 5
CEO Rating 5

Answer 3

将您的逻辑分为两种方式

创建List<String>
迭代列表＆amp;使用String Buffer或Split搜索单词并获得计数器增量。 {做一个简单的逻辑来分离＆＃34; read-barfull＆＃34;和字符串＆＃34;键＆＃34;（即。薪酬和福利）
从中获取计数值。
创建Map<String,Integer> 这就是全部。
