Java 如何获取标记名以特定字符串结尾的所有XML节点

我正在想办法解决一个非常琐碎的问题。 让我们假设我有两个xml文档“家族”：“请求”和“响应”

属于“请求”的文档至少有一个以“请求”结尾的标记名，如下所示：

<MyMessage>
    <doSomethingRequest>
         ...
    </doSomethingRequest>
    ...
</MyMessage>

但显然这不起作用（实际上我很确定这不起作用，因为

org.w3c.dom.Document

中的通配符只允许独立匹配所有标记）

有什么想法吗？

非常感谢

正如所指出的，问题很简单，答案也很简单：使用XPath，函数以结尾

public static String getMessageType(Document xml) {
    try {
        xpathFactory = XPathFactory.newInstance(NamespaceConstant.OBJECT_MODEL_SAXON);
        XPath xpath = xpathFactory.newXPath();


        XPathExpression searchRequest = xpath.compile("//*[ends-with(name(),'Request')]");
        XPathExpression searchResponse = xpath.compile("//*[ends-with(name(),'Response')]");
        NodeList requestResult = (NodeList) searchRequest.evaluate(xml, XPathConstants.NODESET);
        NodeList responseResult = (NodeList) searchResponse.evaluate(xml, XPathConstants.NODESET);

        if(requestResult.getLength() != 0) return "REQ";
        if(responseResult.getLength() != 0) return "RESP";
    } catch (XPathExpressionException e) {
        e.printStackTrace();
        return null;
    } catch (XPathFactoryConfigurationException e) {
        e.printStackTrace();
        return null;
    }
}

public static String getMessageFamily(Document xml){
    if(xml.getElementsByTagName("*Request").getLength() != 0){
        return "I'm a Request!";
    } else if(xml.getElementsByTagName("*Response").getLength() != 0){
        return "I'm a Response!";
    } else {
        return "don't know who I am";
    }
}

public static String getMessageType(Document xml) {
    try {
        xpathFactory = XPathFactory.newInstance(NamespaceConstant.OBJECT_MODEL_SAXON);
        XPath xpath = xpathFactory.newXPath();


        XPathExpression searchRequest = xpath.compile("//*[ends-with(name(),'Request')]");
        XPathExpression searchResponse = xpath.compile("//*[ends-with(name(),'Response')]");
        NodeList requestResult = (NodeList) searchRequest.evaluate(xml, XPathConstants.NODESET);
        NodeList responseResult = (NodeList) searchResponse.evaluate(xml, XPathConstants.NODESET);

        if(requestResult.getLength() != 0) return "REQ";
        if(responseResult.getLength() != 0) return "RESP";
    } catch (XPathExpressionException e) {
        e.printStackTrace();
        return null;
    } catch (XPathFactoryConfigurationException e) {
        e.printStackTrace();
        return null;
    }
}
