比较XML忽略元素顺序 [英] Compare XML ignoring element order

问题描述

使用XMLUnit 2，如何在不考虑元素顺序的情况下比较两个文档?

With XMLUnit 2 how do you compare two documents without taking the element order into account?

我得到了针对XMLUnit 1的问题，但是显然v2中的新API不再具有上述方法.

I got this question for XMLUnit 1, but apparently the new API in v2 doesn't have the mentioned method anymore.

这是我当前的代码:

Diff diff = DiffBuilder.compare(expected)
            .withTest(actual)
            .ignoreComments()
            .ignoreWhitespace()
            .checkForSimilar()
            .build();

assertFalse(diff.hasDifferences());

这些是我与上面代码段比较的两个字符串:

These are the two strings i compare with above snippet:

String expected = "<root><foo>FOO</foo><bar>BAR</bar></root>";
String actual = "<root><bar>BAR</bar><foo>FOO</foo></root>";

报告的差异

Expected element tag name 'foo' but was 'bar' - comparing <foo...> at /root[1]/foo[1] to <bar...> at /root[1]/bar[1] (DIFFERENT)
Expected text value 'FOO' but was 'BAR' - comparing <foo ...>FOO</foo> at /root[1]/foo[1]/text()[1] to <bar ...>BAR</bar> at /root[1]/bar[1]/text()[1] (DIFFERENT)
Expected element tag name 'bar' but was 'foo' - comparing <bar...> at /root[1]/bar[1] to <foo...> at /root[1]/foo[1] (DIFFERENT)
Expected text value 'BAR' but was 'FOO' - comparing <bar ...>BAR</bar> at /root[1]/bar[1]/text()[1] to <foo ...>FOO</foo> at /root[1]/foo[1]/text()[1] (DIFFERENT)

推荐答案

在2.x文档中可能需要更清楚的一个区别是默认的ElementSelector-大致与1.x中的ElementQualifier相同. . 1.x默认情况下按名称匹配元素，而2.x默认情况下按顺序匹配元素.也许这是个坏主意.

One difference that may need to become clearer in the 2.x documentation is the default ElementSelector - roughly what used to be ElementQualifier in 1.x. Where 1.x defaults to match elements by name, 2.x defaults to match elements in order. Maybe this is a bad idea.

如果您切换到元素名称的匹配项，则您的Diff应该起作用.

Your Diff should work if you switch to matching on element names.

.withNodeMatcher(new DefaultNodeMatcher(ElementSelectors.byName))

.withNodeMatcher(new DefaultNodeMatcher(ElementSelectors.byName))
