的Java：验证和获取有关HTML标签信息/属性

Question

我在寻找某种现成的Java库的验证和获取有关信息的内置HTML标签和属性如下所示：

public class MyHTMLGenerator { 

    /** 
    * Accepts tag name and attributes and returns a string containing HTML 
    * element. 
    */ 
    public String createElement(
      String tagName, Map<String, String> tagAttributes) throws Exception { 
     HTMLUtils utils = HTMLUtils.for(HTMLDialects.HTML_5); 
     HTMLTagInfo tagInfo = utils.getTagInfo(tagName); 
     ... 
     // checking that tag name specified is a valid HTML5 tag name 
     // checking that tag attributes' names and values are valid for this tag 
     // does this tag is paired or not? which one to return: 
     // "<p>" or "<p></p>"? 
     // etc. 
     ... 
     return result; 
    } 

}

我推荐Jsoup，它允许您将HTML解析到Java DOM中并对其进行处理。
