I have several files, each file have many such tags within them. What is the best way to extract the data between each of and tags? This is my approach

> for (File file : files) { 
> System.out.println(file.getName());   
> if
> (file.isFile()) {         
> try {
>       BufferedReader bufferReader = new BufferedReader(new FileReader(file));             >       String line; 
>       XContentBuilder builder = null;
>       StringBuffer sb = null; 
>       String descrption= null; 
>       String car =null;   
>       Boolean within_description = false; 
>           String Car= "";
>           while ((line = bufferReader.readLine()) != null) {
>               // System.out.println(line);
>               if (line.equals("<DOC>")) {
>                   builder = jsonBuilder();
>                   sb = new StringBuffer();
>                   continue;
>               } 
>               
>       
>               if (line.contains("<CAR>")) {
>                    
>                   String remove_front_space = line.replaceAll("<CAR>",
>                           "");
>                   car= remove_front_space .replaceAll("</CAR>",
>                           "").trim();
>                   builder = builder.startObject().field("CARR",
>                           car);
>                   continue;
>               }
>               if (line.equals("</DESCRIPTION>")) {
>                   within_description = false;
>                   continue;
>               }
>               if (within_description) {
>                   sb.append(line);
>                   continue;
>               }
>               if (line.equals("<DESCRIPTION>")) {
>                   within_description = true;
>                   continue;
>               }
>               if (line.equals("</DOC>")) {
>                   // JSONifying the string data
>                   text_toadd = sb.toString();
>                   builder = builder.field("text", text_toadd)
>                           .endObject();
>                   sb = null;

----Make database call and store CAR and DESCRIPTION information into Database.

Any suggestion would do. Thanks in advance!
