比较XML时如何忽略某些元素？ [英] How do I ignore certain elements when comparing XML?

问题描述

我有这样的XML消息：

I have an XML message like so:

<root>
  <elementA>something</elementA>
  <elementB>something else</elementB>
  <elementC>yet another thing</elementC>
</root>

我想将被测方法生成的此类消息与预期消息进行比较，但是我不关心 elementA 。所以，我希望上述消息被视为等于：

I want to compare a message of this type produced by a method under test to an expected message, but I don't care about elementA. So, I'd like the above message to be considered equal to:

<root>
  <elementA>something different</elementA>
  <elementB>something else</elementB>
  <elementC>yet another thing</elementC>
</root>

我正在使用最新版本的 XMLUnit 。

I'm using the latest version of XMLUnit.

我想这个答案涉及创建自定义 DifferenceListener ;如果有可以在那里使用的话，我只是不想重新发明轮子。

I'm imagining that the answer involves creating a custom DifferenceListener; I just don't want to reinvent the wheel if there's something ready to use out there.

欢迎使用XMLUnit以外的库的建议。

Suggestions that use a library other than XMLUnit are welcome.

推荐答案

XMLUnit ，因为这个问题已得到解答。

Things have changed a lot for XMLUnit since this question was answered.

现在，您可以在使用 DiffBuilder ：

final Diff documentDiff = DiffBuilder
            .compare(expectedSource)
            .withTest(actualSource)
            .withNodeFilter(node -> !node.getNodeName().equals(someName))
            .build();

如果你再调用 documentDiff.hasDifferences（）添加到过滤器的节点将被忽略。

If you then call documentDiff.hasDifferences() nodes added to filter will be ignored.
