以另一种格式读取和转换XML文件中的数据（以使用Gate Embedded注释）

Question

我在我的程序Java中从GUI Developer Gate调用我的应用程序，然后我将我的文档注释为格式XML.But现在我无法在XML文件中提取我的数据。你能帮帮我吗？

  Corpus corpus = Factory.newCorpus("Processing CV");

     CorpusController application = 
     (CorpusController)PersistenceManager.loadObjectFromUrl(new URL("file:////home/NafisehApp.xgapp"));
     application.setCorpus(corpus);

     File[] files = getFilesFromDir("/home/GAte/TestCV.pdf");
        for (int i = 0; i < files.length; i++) {
          if (!files[i].getName().endsWith(".pdf"))
             continue;
            File docFile = files[i];
        gate.Document doc =Factory.newDocument(docFile.toURI().toURL());
        corpus.add(doc);
        application.execute();

    AnnotationSet defaultAnnotSet = doc.getAnnotations();
          Set<String> annotTypesRequired = new HashSet<String>();
          annotTypesRequired.add("Person");
          annotTypesRequired.add("Address");
          annotTypesRequired.add("Title");
     File outputFile = new File("/home/GAte/file.xml");
         DocumentStaxUtils.writeDocument(doc, outputFile);
   FileUtils.write(outputFile,doc.toXml(doc.getAnnotations().get(annotTypesRequired), true));
