SAX Parser相同的标签覆盖值

标签: android xml-parsing sax saxparser

我正在使用SAX Parser来处理我正在处理的Android应用程序,并且我很难尝试保存Project的名称标签而不被覆盖。这里的问题是项目中的名称标签被许可证中的名称标签覆盖,因为标签是相同的。剩下的就是解析得很漂亮。此外,通过将GET请求传递给API来生成此xml,因此我无法对其进行编辑。有没有办法可以省略许可证字段中的名称标签,或者尝试了解我在文档内部的位置,这是一个问题,因为SAX甚至被驱动。此外,我意识到我可以使用DOM轻松完成这项工作,但现在我已经走得太远而无法切换到DOM。我已经附加了我的XML处理代码和我试图解析的xml文件的片段。

@Override
public void startElement (String namespaceURI, String localName, String qName, Attributes attributes) throws SAXException 
{
    buffer.setLength(0);

    if (localName.equalsIgnoreCase("result"))
    {
        results = new ArrayList <Result> ();
    }

    if (localName.equalsIgnoreCase("project"))
    {
        result = new Result ();
    }

    if (localName.equalsIgnoreCase("name"))
    {
        result.name = buffer.toString ();
        Log.v("PROJECT NAME: ", result.name);
    }
} // end of startElement ()

    {
            this.entries++;
            results.add(result);
    }

    else if (localName.equalsIgnoreCase("id"))

您可以通过简单的方式解决问题。

  1. 在您的类处理程序中创建一些标志。

    private boolean inProject = false;
    private boolean inLicense = false;
    
  2. 控制这些标志,就像我在下面给你看的那样。

       @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;
               }
           }
        }
    
  3. 让我知道它是否有效。
