问题描述
我有两个 XML 文件:
I have two XML files:
<!------------------------File1--------------------------------->
<note id="ignoreThisAttribute_1">
<to>Experts</to>
<from>Matrix</from>
<heading id="dontIgnoreThisAttribute_1">Reminder</heading>
<body>Help me with this problem</body>
</note>
<!------------------------File2--------------------------------->
<note id="ignoreThisAttribute_2">
<to>Experts</to>
<from>Matrix</from>
<heading id="dontIgnoreThisAttribute_2">Reminder</heading>
<body>Help me with this problem</body>
</note>
在比较这两个文件时，我必须忽略 Node:note 的属性:id.
I have to ignore the attribute:id of Node:note while comparing these two files.
我正在使用 DiffBuilder:
Diff documentDiff = DiffBuilder.compare(srcFile).withTest(destFile).build()
大多数在线解决方案建议实现 DifferenceEvaluator:
Most online solutions suggested implementing DifferenceEvaluator:
也试过了，但这会忽略所有具有属性 id 的节点，而我想忽略来自特定节点的属性:
Tried that as well, but this ignores all nodes with attribute id, whereas I want to ignore an attribute from a specific node:
public class IgnoreAttributeDifferenceEvaluator implements DifferenceEvaluator {
private String attributeName;
public IgnoreAttributeDifferenceEvaluator(String attributeName) {
this.attributeName = attributeName;
}
@Override
public ComparisonResult evaluate(Comparison comparison, ComparisonResult outcome) {
if (outcome == ComparisonResult.EQUAL)
return outcome;
final Node controlNode = comparison.getControlDetails().getTarget();
System.out.println(controlNode.getNodeName());
if (controlNode instanceof Attr) {
Attr attr = (Attr) controlNode;
if (attr.getName().equals(attributeName)) {
return ComparisonResult.EQUAL;
}
}
return outcome;
}
}
在我的测试类中调用方法:
Calling method in my Test class:
final Diff documentDiff = DiffBuilder.compare(src).withTest(dest)
.withDifferenceEvaluator(new IgnoreAttributeDifferenceEvaluator("id"))
.build();
有人可以建议我使用 XMLUnit 2.x 实现这一目标的方法吗XMLUnit 的新手，因此请提供相应的帮助.
Can someone suggest me a way I can achieve this using XMLUnit 2.x New to XMLUnit so please help accordingly.
提前致谢.
推荐答案
如果你真的想要，你可以使用 DifferenceEvaluator.除了属性本身的名称之外，您所要做的就是测试 Attr 的所有者元素"名称的名称.
You could use a DifferenceEvaluator if you really wanted to. All you'd have to do was testing the name of the Attr's "owner element"'s name in addition to the name of the attribute itself.
但 XMLUnit 2.x 对此提供了不同的解决方案:AttributeFilter.代码与您已经获得的 DifferenceEvaluator 不会有太大不同，但您不会混淆关注点.
But XMLUnit 2.x offers a different solution to this: AttributeFilter. The code won't be that different from the DifferenceEvaluator you've already got, but you won't be mixing concerns.
class IgnoreNoteId implements Predicate<Attr> {
public boolean test(Attr attr) {
return !("note".equals(attr.getOwnerElement().getNodeName())
&& "id".equals(attr.getNodeName()));
}
}
使用 Java8 时，在 withAttributeFilter 中使用 lambda 甚至更短.
or even shorter with a lambda in withAttributeFilter when using Java8.
