使用Java解析带有4级XML文件的XML文件

标签： xml parsing

我正在尝试解析此文件和不同级别以获取完全拥有我的数据。请帮忙。我可以解析一个级别的文件但是这个文件正在扼杀我。当我终于认为我得到它然后我进一步搞砸了。我需要遍历UserModel记录。我需要解析的编程语言是Java。下面我提供了两个样本。 XML文件和我正在编写的代码。我不认为我正在向下钻取我想要循环的元素。在这个示例中，我只能获得一个记录实例并且循环停止。所以有些事情显然是错的。

现在这里是我的Java代码，我开始这样做：

       File fXmlFile = new File("C:\\Users\\User\\Documents\\testUsers.xml");
    Document dom = (Document) db.parse(fXmlFile);
    Element docEle = dom.getDocumentElement();
    NodeList nl = docEle.getChildNodes();

 if (nl != null && nl.getLength() > 0) {
        for (int i = 0; i < nl.getLength(); i++) {
         //  System.out.println("Node type is: "+nl.item(i).getNodeType());
          // System.out.println("Element Node is: "+Node.ELEMENT_NODE);
            if (nl.item(i).getNodeType() == Node.ELEMENT_NODE) {
                 Element el = (Element) nl.item(i);
                // System.out.println("Node Name: "+el.getNodeName());
                //System.out.println(el.getElementsByTagName("a:UserModel").item(0).getTextContent());
            if (el.getNodeName().contains("a:UserModel")) {

我在有关java的更新之前发布了此消息。我将把它留下来，因为此解决方案的xpath部分应该可以转移到基于java的解决方案。
