Question

我遇到了一个真正需要帮助的问题。我负责创建一个应用程序。该应用程序有一些要求如下：

读取* .jrxml（JasperReport xml）文件。
需要记录任何对象的属性。例如，TextField具有字体大小，名称等
将它们保存为spec文档。（见图）

这里的问题是如何动态地读取具有其属性的对象;因为不同的报告（* .jrxml）具有不同的xml格式。有任何想法吗？请帮忙......

以下是我已经尝试过的事情：

JRXML代码：

Java代码：

try{
    File xmlFile = new File("jrxml.jrxml");
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
    Document document = dBuilder.parse(xmlFile);
    document.getDocumentElement().normalize();

    Element element = (Element) document.getDocumentElement();
    NodeList nodeList = element.getChildNodes();

    for(int i=0; i<nodeList.getLength(); i++){
       Node node = nodeList.item(i);
       if(node instanceof Element){
           Element child = (Element) node;
           String tagName = child.getTagName();
           System.out.println(tagName);
       } 

    }
}
catch(Exception e){
    e.printStackTrace();
}

结果：它读了什么。
