使用Jsoup刪除所有HTML但保留行

Question

我有一個String其中包含一些電子郵件的內容，我想從此String刪除所有HTML編碼。

這是我的時刻代碼：

public static String html2text(String html) { 

    Document document = Jsoup.parse(html); 
    document = new Cleaner(Whitelist.basic()).clean(document); 
    document.outputSettings().escapeMode(EscapeMode.xhtml); 
    document.outputSettings().charset("UTF-8"); 
    html = document.body().html(); 

    html = html.replaceAll("<br />", ""); 

    splittedStr = html.split("Geachte heer/mevrouw,"); 

    html = splittedStr[1]; 

    html = "Geachte heer/mevrouw,"+html; 

    return html; 
} 

此方法刪除所有的HTML，不斷線且大部分佈局。但它也會返回一些&和nbsp;標籤，這些標籤並未完全刪除。請參閱下面的輸出，因爲您可以看到在String中仍有一些標籤甚至是其中的一部分。我如何擺脫這些？

 Loonheffingen       &n= bsp; Naam 
nr         in administratie         &nbs= p;           meldingen 
 nummer 

1          &n= bsp;            = ;     0            &= nbsp;           &nbs= p;           1 
      123456789L01

這是HTML我試圖解析的一部分。我想刪除所有的HTML，但保留原始電子郵件的佈局。

任何幫助表示讚賞，

謝謝！

 Document xmlDoc = Jsoup.parse(file, "", Parser.xmlParser()); 
     Elements spans= xmlDoc.select("span"); 

     for (Element link : spans) { 
      String html = textPlus(link); 
      System.out.println(html); 
     } 


public static String textPlus(Element elem) { 
    List<TextNode> textNodes = elem.textNodes(); 
    if (textNodes.isEmpty()) { 
     return ""; 
    } 

    StringBuilder result = new StringBuilder(); 
    // start at the first text node 
    Node currentNode = textNodes.get(0); 
    while (currentNode != null) { 
     // append deep text of all subsequent nodes 
     if (currentNode instanceof TextNode) { 
      TextNode currentText = (TextNode) currentNode; 
      result.append(currentText.text()); 
     } else if (currentNode instanceof Element) { 
      Element currentElement = (Element) currentNode; 
      result.append(currentElement.text()); 
     } 
     currentNode = currentNode.nextSibling(); 
    } 
    return result.toString(); 
} 

守則作爲this問題的答案提供了依據。

而不是這樣做，您需要遍歷JSoup返回的HTML結構並整理文本節點。這樣，你讓JSoup確定什麼是真正的文本，並且將爲你處理實體編碼（例如& - >&等）。
