XMLUnit与HTML文件的不同

Question

我正在尝试对两个HTML文档使用XMLUnit的diff。为此，我将它们转换为字符串，然后从这两个字符串构造一个diff对象。

但是，这会抛出以下SAXException：

[Fatal Error] :1:177: The element type "br" must be terminated by the matching end-tag "</br>".
org.xml.sax.SAXParseException: The element type "br" must be terminated by the matching end-tag "</br>".

因此，我需要将此HTML转换为有效的XML。我看到XMLUnit提供了HTMLDocumentBuilder，它似乎提供了一种方法来实现这一点，但仅用于XPath评估。有什么简单的方法可以转换成有效的超文本标记语言，这样我就可以做XMLUnit比较了？

您可以使用HTMLDocumentBuilder的parse方法从您的HTML输入创建一个Document。Diff和XMLUnit的difference engine的其他部分将愉快地与Document一起工作。

请注意，HTMLDocumentBuilder有点麻烦，您可能更适合使用专门处理HTML转换的库，比如jTidy。
