Java HTML格式化程序到底做什么？

html格式化程序做什么？我已使用以下html格式化程序格式化了一个html文件：

但是当我比较这两个文件时，我只能找到一个不同点，那就是缩进。对于某些需要解析html文件的项目，我无法使用jsoup解析未格式化的html文件，但在格式化html后，jsoup正在解析html文件。 用于解析的代码：

public Document parseHTML(String filePath)  throws IOException{

        File inputFile = new File(filePath); 
        Document fileDoc = Jsoup.parse(inputFile, null);
        return fileDoc;
     }

你问题的答案是什么

html格式化程序做什么

位于您共享的链接的第一行：

使用所需缩进级别格式化HTML字符串/文件。这个 格式化规则是不可配置的，但我认为它为用户提供了 以尽可能最好的输出

因此，它只是缩进HTML字符串，这样它将被视为有效的HTML字符串

一些格式化程序使您的代码如此美丽，以至于您感到欣喜若狂，例如：

哦，是的！

顾名思义，它基本上是格式化html的，在大多数情况下更容易让人阅读。如果jsoup只处理格式化的html，并且除了空格和换行符之外没有其他区别，那么就在上面发布一个问题（或者重新表述这个问题，尤其是标题）-别忘了发布一个简单的例子，说明未格式化的html不起作用，格式化的版本也起作用。
