XML 文档 - 检查父节点然后遍历文档

Question

我在尝试遍历 XML 文档时遇到了挑战。请帮忙。

对于文档 1，我的方法通过首先检查父节点，然后提取子节点信息。
我现在有 2 XML 个输出，第二个与第一个不同，我
检查一个，然后提取必要的信息，但对于文档二有多个条目我需要提取
两个文件彼此不同
我正在关注一些在线示例，这很有帮助，请问您是否可以帮助编写下面文档二的代码
调试时我可以检查文档和节点，但我看到了它们我正在努力提取信息
int length = nlist.getLength()，这总是Zero/0，改变 getElementsByTagName 它 returns 长度为 3.

此代码适用于第一个文档

NodeList nodeList = xmlDocument.getElementsByTagName("add:MemberKey");
            for (int i = 0; i < nodeList.getLength(); i++) {
                Node currentNode = nodeList.item(i);
                if (currentNode.getNodeType() != Node.ELEMENT_NODE)
                    continue;
                Element currentElement = (Element)currentNode;
                String tagValue = null;
                tagValue = getElementValue("add:MemberCID",currentElement);
                System.out.println(tagValue);
            }

这是我的第二份文件

检查我的第二个文档的代码：我很挣扎

public static checkMessageType(org.w3c.dom.Document xmlDocument) {
    Element docEle = xmlDocument.getDocumentElement();
    NodeList nlist= docEle.getElementsByTagName("bbb:CreateMemberResultAnnotation");
    int length = nlist.getLength(); // I am getting a 0 length here, 
    List<Element> childElement = new ArrayList<>();
    for (int i = 0; i < nlist.getLength(); i++) {
        //Node node = nlist.item(i).getOwnerDocument().getDocumentElement();
       // if (node instanceof Element) {
           // childElement.add((Element) node);
        if (nlist.item(i).getNodeType() == Node.ELEMENT_NODE) {
            Element el = (Element) nlist.item(i);
            if (el.getNodeName().contains("bbb:MemberInst")) {
                String XMLMemberID = el.getElementsByTagName("add:MemberID").item(0).getTextContent();
                String XMLMemberSeq = el.getElementsByTagName("add:MemberSeq").item(0).getTextContent();
            }
        }
 }

Answer 1

您的 xml 是否已解析？第 10 行的 p 标签是什么？它没有在任何地方关闭。在第 36 行也有一个 createMemberResult 结束标记，但在此之前没有打开标记

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

    <bbb:CreateMemberResultAnnotation xmlns:bbb="http://www.google.com">

此处测试运行成功：

      @Test
   public void test() throws ParserConfigurationException, SAXException, IOException {
      DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
      DocumentBuilder builder = factory.newDocumentBuilder();
      URL resource = getClass().getResource("/yourxml.xml");
      Document xmlDocument = builder.parse(resource.openStream());
      Element docEle = xmlDocument.getDocumentElement();
      NodeList nlist = docEle.getElementsByTagName("bbb:CreateMemberResultAnnotation");
      int length = nlist.getLength(); // I am getting a 0 length here,
      List<Element> childElement = new ArrayList<>();
      for (int i = 0; i < nlist.getLength(); i++) {
         // Node node = nlist.item(i).getOwnerDocument().getDocumentElement();
         // if (node instanceof Element) {
         // childElement.add((Element) node);
         if (nlist.item(i).getNodeType() == Node.ELEMENT_NODE) {
            Element el = (Element) nlist.item(i);
            if (el.getNodeName().contains("bbb:MemberInst")) {
               String XMLMemberID = el.getElementsByTagName("add:MemberID").item(0).getTextContent();
               String XMLMemberSeq = el.getElementsByTagName("add:MemberSeq").item(0).getTextContent();
            }
         }

      }
   }
