xml - XML 与 XMLUnit 的比较在列表具有不同复杂元素和排序的特定场景中不起作用

Question

我有以下带有客户列表的 XML，每个客户都有交易列表。我已经设法编写 XMLUnit 代码来忽略客户的顺序而不是交易。交易有一些独特的结构（不能改变）。以下是示例 XML 和代码。请帮忙。

XML 1：

<Customers>
  <Customer>
    <Id>1</Id>
    <Transactions>
      <Transaction>
        <CashTransaction>
          <amount>100</amount>
        </CashTransaction>
      </Transaction>
      <Transaction>
        <CardTransaction>
          <amount>200</amount>
        </CardTransaction>
      </Transaction>
    </Transactions>
  </Customer>
  <Customer>
    <Id>2</Id>
    <Transactions>
      <Transaction>
        <CardTransaction>
          <amount>500</amount>
        </CardTransaction>
      </Transaction>
      <Transaction>
        <CashTransaction>
          <amount>400</amount>
        </CashTransaction>
      </Transaction>
    </Transactions>
  </Customer>
</Customers>

XML 2：

<Customers>
  <Customer>
    <Id>2</Id>
    <Transactions>
      <Transaction>
        <CashTransaction>
          <amount>400</amount>
        </CashTransaction>
      </Transaction>
      <Transaction>
        <CardTransaction>
          <amount>500</amount>
        </CardTransaction>
      </Transaction>
    </Transactions>
  </Customer>
  <Customer>
    <Id>1</Id>
    <Transactions>
      <Transaction>
        <CardTransaction>
          <amount>200</amount>
        </CardTransaction>
      </Transaction>
      <Transaction>
        <CashTransaction>
          <amount>100</amount>
        </CashTransaction>
      </Transaction>
    </Transactions>
  </Customer>
</Customers>

代码：

    Diff diffs = DiffBuilder.compare(Input.from(resourceAsStream1))
        .withTest(Input.from(resourceAsStream2))
        .ignoreComments()
        .ignoreWhitespace()
        .normalizeWhitespace()
        .checkForSimilar()
        .withDifferenceEvaluator(evaluator)
        .withNodeMatcher(new DefaultNodeMatcher(ElementSelectors.conditionalBuilder()
            .whenElementIsNamed("Customer")
            .thenUse(ElementSelectors.byXPath("./Id", ElementSelectors.byNameAndText))
            .elseUse(ElementSelectors.byName)
            .build()
        )).build();

显示的差异：

Expected child 'CashTransaction' but was 'null' - comparing <CashTransaction...> at /Customers[1]/Customer[1]/Transactions[1]/Transaction[1]/CashTransaction[1] to <NULL>
Expected child 'null' but was 'CardTransaction' - comparing <NULL> to <CardTransaction...> at /Customers[1]/Customer[2]/Transactions[1]/Transaction[1]/CardTransaction[1]
Expected child 'CardTransaction' but was 'null' - comparing <CardTransaction...> at /Customers[1]/Customer[1]/Transactions[1]/Transaction[2]/CardTransaction[1] to <NULL>
Expected child 'null' but was 'CashTransaction' - comparing <NULL> to <CashTransaction...> at /Customers[1]/Customer[2]/Transactions[1]/Transaction[2]/CashTransaction[1]
