在比较XML时,如何忽略某些元素?

xmlunit junit xml java

Paul Morie · 技术社区 · 17 年前

我有一条这样的XML消息:

<root>
  <elementA>something</elementA>
  <elementB>something else</elementB>
  <elementC>yet another thing</elementC>
</root>

elementA

<root>
  <elementA>something different</elementA>
  <elementB>something else</elementB>
  <elementC>yet another thing</elementC>
</root>

DifferenceListener

我最终实施了一个 DifferenceListener 这需要一个节点名称列表(带命名空间)来忽略以下内容的文本差异:

public class IgnoreNamedElementsDifferenceListener implements DifferenceListener {
    private Set<String> blackList = new HashSet<String>();

    public IgnoreNamedElementsDifferenceListener(String ... elementNames) {
        for (String name : elementNames) {
            blackList.add(name);
        }
    }

    public int differenceFound(Difference difference) {
        if (difference.getId() == DifferenceConstants.TEXT_VALUE_ID) {
            if (blackList.contains(difference.getControlNodeDetail().getNode().getParentNode().getNodeName())) {
                return DifferenceListener.RETURN_IGNORE_DIFFERENCE_NODES_IDENTICAL;
            }
        }

        return DifferenceListener.RETURN_ACCEPT_DIFFERENCE;
    }

    public void skippedComparison(Node node, Node node1) {

    }
}

事情已经发生了很大的变化 XMLUnit 因为这个问题得到了回答。

现在,您可以在使用时轻松忽略节点 DiffBuilder :

final Diff documentDiff = DiffBuilder
            .compare(expectedSource)
            .withTest(actualSource)
            .withNodeFilter(node -> !node.getNodeName().equals(someName))
            .build();

documentDiff.hasDifferences()

identity transform 过滤掉我想忽略的元素,并比较结果。

您现在可以尝试 ${xmlunit.ignore}

Diff diff = DiffBuilder
    .compare(expectedXML)
    .withTest(actualXML)
    .withDifferenceEvaluator(new PlaceholderDifferenceEvaluator())
    .build();

<root>
  <elementA>${xmlunit.ignore}</elementA>
  <elementB>something else</elementB>
  <elementC>yet another thing</elementC>
</root>

实际XML:

<root>
  <elementA>anything</elementA>
  <elementB>something else</elementB>
  <elementC>yet another thing</elementC>
</root>

请注意,目前${xmlunit.ignore}只支持文本节点和属性值忽略,从 unit tests .

忽略节点 不管你想忽略多少节点的长度,或者你不知道 ,按照以下简单步骤操作

public static void XMLdiff(String XML1, String XML2){
               
 //nodes you wanted to ignore
        String[] ignoreNodes = {"nodeX", "nodeY", "nodeZ"};
      
//testnode(node,ignoreNodes) is handled below for finding and ignoring multiple nodes
        final Diff documentDiff = DiffBuilder.compare(XML1)
                                  .withTest(XML2)
                                  .withNodeFilter(node->testnode(node,ignoreNodes))
                                  .build();
}

private static boolean testnode(Node node, String[] name) {

        for (int i = 0; i < name.length; i++) {

            if (node.getNodeName().toString().equals(name[i])) {
                return false;
            }
            if (name.length == 0) {
                break;
            }
        }
        return true;
    }
