我正在为我正在开发的安卓应用程序使用SAX Parser,我很难保存Project的名称标签以免被覆盖。这里的问题是,我在项目中的名称标记被许可证中的名称标签覆盖,因为标签是相同的。剩下的正在被完美地解析。此外,这个xml是通过将GET请求传递给API生成的,所以我无法编辑它。有没有办法省略许可证字段中的name标记,或者试图了解我在文档中的位置,这是一个问题,因为SAX甚至是驱动的。此外,我意识到使用DOM可以很容易地实现这一点,但我现在已经走得太远了,无法切换到DOM。我已经附上了我的XML处理代码片段和我试图解析的XML文件。
感谢

您可以用一种简单的方式解决问题。
-
在类处理程序中创建一些标志。
private boolean inProject = false; private boolean inLicense = false;
-
像我下面展示的那样控制这些旗帜。
@Override public void startElement (String namespaceURI, String localName, String qName, Attributes attributes) throws SAXException { if (localName.equalsIgnoreCase("project")) { this.inProject = true; } else if (localName.equalsIgnoreCase("license")) { this.inLicense = true; } } @Override public void endElement (String namespaceURI, String localName, String qName) throws SAXException { if (localName.equalsIgnoreCase("name") { if(inProject) { //Set your project name here. this.inProject = false; } else if (inLicense) { //Set your lencense name here. this.inLicense = false; } } }
如果有效,请告诉我。
