我能够获得总流量为 3。但是我无法获得元素 ApiName 及其子元素的所有请求响应。

这就是我正在尝试的方法。

 SAXBuilder builder = new SAXBuilder();
          File xmlFile = new File("flowmodeling.xml");
          Document document = (Document) builder.build(xmlFile);
          Element e = document.getRootElement();
          List songElements = document.getRootElement().getChildren("Flow");    

我想获得 ApiName 及其子项的所有请求响应。

请帮帮我

您只需迭代列表 SongElements 即可检索所有元素，例如:

    SAXBuilder builder = new SAXBuilder();
    File xmlFile = new File("flowmodeling.xml");
    Document document = (Document) builder.build(xmlFile);
    Element e = document.getRootElement();
    List<Element> songElements = document.getRootElement().getChildren("Flow"); 

    for(Element element : songElements) {
        Element apiName =  element.getChild("ApiName");
        System.out.println(apiName.getAttribute("name"));

        Element request = apiName.getChild("Request");
        System.out.println(request.getValue());

        Element response = apiName.getChild("Response");
        System.out.println(response.getValue());
    }

希望有帮助。
