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

我有一个像这样的 XML 消息:

I have an XML message like so:

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

我想将被测方法产生的这种类型的消息与预期的消息进行比较，但我不关心 elementA.因此，我希望将上述消息视为等于:

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>

我使用的是最新版本的 XMLUnit.

I'm using the latest version of XMLUnit.

我想象答案涉及创建一个自定义的DifferenceListener；如果有可用的东西，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.

欢迎提出使用 XMLUnit 以外的库的建议.

Suggestions that use a library other than XMLUnit are welcome.

推荐答案

XMLUnit 因为这个问题得到了回答.

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

您现在可以在使用 DiffBuilder 时轻松忽略节​​点:

You can now easily ignore a node when using a DiffBuilder:

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

如果你然后调用 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.
