問題描述
我有兩個 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>
在比較這兩個文件時，我必須忽略 Node:note 的屬性: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()
大多數(shù)在線解決方案建議實現(xiàn) DifferenceEvaluator:
Most online solutions suggested implementing DifferenceEvaluator:
也試過了，但這會忽略所有具有屬性 id 的節(jié)點，而我想忽略來自特定節(jié)點的屬性:
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;
}
}
在我的測試類中調(diào)用方法:
Calling method in my Test class:
final Diff documentDiff = DiffBuilder.compare(src).withTest(dest)
.withDifferenceEvaluator(new IgnoreAttributeDifferenceEvaluator("id"))
.build();
有人可以建議我使用 XMLUnit 2.x 實現(xiàn)這一目標的方法嗎XMLUnit 的新手，因此請?zhí)峁┫鄳?yīng)的幫助.
Can someone suggest me a way I can achieve this using XMLUnit 2.x New to XMLUnit so please help accordingly.
提前致謝.
推薦答案
如果你真的想要，你可以使用 DifferenceEvaluator.除了屬性本身的名稱之外，您所要做的就是測試 Attr 的所有者元素"名稱的名稱.
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 對此提供了不同的解決方案:AttributeFilter.代碼與您已經(jīng)獲得的 DifferenceEvaluator 不會有太大不同，但您不會混淆關(guān)注點.
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 時，在 withAttributeFilter 中使用 lambda 甚至更短.
or even shorter with a lambda in withAttributeFilter when using Java8.
