java - XMLUnit 与 HTML 文件的差异

Question

我正在尝试将 XMLUnit 的 diff 与两个 HTML 文档一起使用。为此，我将它们转换为字符串，然后从两个字符串构造一个 diff 对象。

但是，这会引发以下 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做到这一点，但仅用于 XPath 评估。转换为有效 HTML 以便我可以进行 XMLUnit diff 的简单方法是什么？

Answer 1

您可以使用 HTMLDocumentBuilder 的 parse 方法从 HTML 输入创建 Document。 Diff 和 XMLUnit 差异引擎的其他部分将很乐意与 Document 一起使用。

请注意，HTMLDocumentBuilder 有点破解，您可能更适合专门从事 HTML => XML 转换的库，例如 jTidy。
