我有 2 个 xml 文件，a.xml并且是一些节点值已更改的修改版本。现在我想检查我的代码，只有特定的节点值可以更改，而不是所有节点。我怎样才能在java中进行这个检查？我从用户那里得到这个 xml，如果他更改了我不应该允许的其他节点，他只能更改特定节点。下面是 xml 你可以看到b.xmlb.xmla.xml

<xt:path>HelloWorld/BusinessServices/Mytest</xt:path>两者都发生了变化这是有效的情况，因为他也发生了变化

<xt:value xsi:type="xs:string" xmlns:xs="http://www.w3.org/2001/XMLSchema">40</xt:value>从 30 到 40 这是无效的。

尝试用于 Java 的 XMLUnit。

XMLUnit for Java 提供了两个 JUnit 扩展类，XMLAssert 和 XMLTestCase，以及一组支持类（例如 Diff、DetailedDiff、Transform、SimpleXpathEngine、Validator、NodeTest），这些类允许对以下内容进行断言：

  • 两段 XML 的区别

  • 使用 XSLT 转换一段 XML 的结果

  • 对一段 XML 的 XPath 表达式求值

  • 一段 XML 的有效性

  • 由 DOM Traversal 公开的一段 XML 中的各个节点

    XMLUnit for Java 还可以将 HTML 内容（甚至是格式错误的 HTML）视为有效的 XML，以允许对网页内容进行这些断言。

可以在此处找到另一个 DocumentBuilder 解决方案。

嗯，您可以使用 DocumentBuilder 阅读这两个文件。将节点存储在例如一些列表中，您可以在阅读它们后进行比较：

DocumentBuilderFactory fac = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = fac.newDocumentBuilder();
Document doc = builder.parse(new File("a.xml");

之后，您可以从文档中获取所有节点（存储在 NodeList 中）

NodeList list = doc.getElementsbyName("someelement"); //just for an example

希望我能帮到你一点
