XML 使用 XML 单元进行比较在重新排序元素时不起作用

Question

我有两个 XML

<books><book language="English"><authors><author>Niklaus Wirth</author></authors></book><book language="English"><authors><author>Mark Twain</author></authors></book><book language="English"><authors><author>O.-J. Dahl</author></authors></book></books>


<books><book language="English"><authors><author>Niklaus Wirth</author></authors></book><book language="English"><authors><author>O.-J. Dahl</author></authors></book><book language="English"><authors><author>Mark Twain</author></authors></book></books>

最后两个<author>标签的顺序不同，应该是相似的。这是代码

public static void compare() throws FileNotFoundException{
        String sourceXML=convertXMLtoString(source);
        String targetXML=convertXMLtoString(target);
        System.out.println(sourceXML);
        System.out.println(targetXML);
        Diff mydiff=DiffBuilder.compare(sourceXML)
        .withTest(targetXML)
        .withNodeMatcher(new DefaultNodeMatcher(ElementSelectors.byNameAndText))
        .checkForSimilar()
        //.withNodeMatcher()
        .build();
        Iterable<Difference> differences = mydiff.getDifferences();
        for(Difference d:differences){
            System.out.println(d.toString());
        }
    }

这是输出。

Expected child 'author' but was 'null' - comparing <author...> at /books[1]/book[2]/authors[1]/author[1] to <NULL> (DIFFERENT)
Expected child 'null' but was 'author' - comparing <NULL> to <author...> at /books[1]/book[2]/authors[1]/author[1] (DIFFERENT)
Expected child 'author' but was 'null' - comparing <author...> at /books[1]/book[3]/authors[1]/author[1] to <NULL> (DIFFERENT)
Expected child 'null' but was 'author' - comparing <NULL> to <author...> at /books[1]/book[3]/authors[1]/author[1] (DIFFERENT)

任何人都可以告诉我如何忽略这个吗？我认为将 NameandText 与元素选择器一起使用应该忽略该顺序。谢谢

Answer 1

使用 byNameAndText 确保选择正确的 author 标签，但这已经太晚了，因为 XMLUnit 需要 select 正确的 book 来进行比较成功。一旦确定要比较哪个 book 元素，它就永远不会在不同的子树中搜索元素。

我不认为 author 最终区分了这些书，但在没有任何其他提示的情况下，类似于

ElementSelectors.conditionalBuilder()
    .whenElementIsNamed("book").thenUse(ElementSelectors.byXPath("./authors/author", ElementSelectors.byNameAndText))
    .elseUse(ElementSelectors.byNameAndText)
    .build();

应该可以。
