如何從字符串

Question

獲取文本計數我有以下字符串

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> 
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> 
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> 
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> 
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> 

我需要顯示計數像下面的格式（沒有「讀barfull」的計數）

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

請幫助我得到格式 提前謝謝

Answer 1

如果您要計數的「標記」字符串是靜態的（或至少「預定義」），您可以執行以下操作，它使用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

獨立的邏輯分成兩路

1. 創建List<String>
2. 迭代列表&使用搜索字符串緩衝區或拆分單詞並獲得計數器遞增。 {做簡單的邏輯來分隔「讀barfull」和字符串「key」（即沙利和好處）
3. 從中獲得計數值。
4. 創建一個Map<String,Integer> 這就是所有。

Answer 3

以下是您如何使用Jsoup（因爲您的問題標有它）。總的想法是通過線

• 讀取HTML線，
• 獲取文本通過這條線的HTML
• 選擇所有<span class="read-barfull"></span>元素（無論它們是否爲空或不表示，但如果你可以改變它想） - 簡單select("span.read-barfull")將選定span元素我們
• 打印計數做到這一點（size()在這裏很有用）

代碼：

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()); 
} 

輸出：

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