Extract the table data

Question

Hi
i am having a table data...where i want t read that data and put it in another desired format:
Here is the actual data:
sno     Description     Qty.     Units     Rate (Rs.)     Value (Rs.)
1     Aviation Lamp     1     Nos     3700     3,700
2     Lighting Arrester     1     Nos     1600     1,600
3     Aviataion Lamp Cable     31     Rmt          270     8,370
     Gross Total                    13,670
     The     above     Total include     Services     Tax Amount of     Rs     536                    
     Total Invoice Value     I                    13,670
     Now Claimed 100% of Invoice Value                    13,670
(Rupees Thirteen Thousand Six Hundred and Seventy only)           
My Desired ouput should be in
S.No 1
Description Aviation Lamp
Qty. 1
Units Nos
Rate (Rs.) 3700
Value (Rs.) 3700
S.No 2
Description Lighting Arrester
Qty.1
Units Nos
Rate (Rs.) 1600
Value (Rs.) 1600
S.No 3
Description Aviataion Lamp Cable
Qty.31
Units Nos Rmt
Rate (Rs.) 270
Value (Rs.) 8,370
Gross Total 13,670
Tax Amount of Rs 536
Total Invoice Value 13,670
i have written code like this:
import java.io.BufferedReader;
import java.io.FileReader;
public class TabDeli {
    String LineFeed=null,line=null,Output=null; int ctr=0;
BufferedReader in = new BufferedReader(new FileReader("D:\\tab2.txt"));
                                while ((line = in.readLine()) != null) {
                    LineFeed  += line;
                    ctr++;
String substring;
    LineFeed = LineFeed.substring(4);               
int ptr = ctr-4; String LineFeed2 = LineFeed;
for (int i=1; i<ptr;i++){
       try{
        Output +=("S.No " + LineFeed2.substring(0,LineFeed2`.IndexOf("$")+"/n"));
        LineFeed2 = LineFeed2.substring(IndexOf("$")+1);
        Output += "Description "
                   + LineFeed2.substring(0,LineFeed2.IndexOf("$")+"\n";
        LineFeed2 = LineFeed2.substring(IndexOf("$")+1);
        Output += ("Qty. " + LineFeed2.substring(0,LineFeed2.IndexOf("$")+"\n");
        LineFeed2 = LineFeed2.substring(IndexOf("$")+1);
        Output += ("Units " + LineFeed2.substring(0,LineFeed2.IndexOf("$")+"\n"));
        LineFeed2 = LineFeed2.substring(IndexOf("$")+1);
        Output +=( "Rate (Rs.) "
                   + LineFeed2.substring(0,LineFeed2.IndexOf("$")+"\n"));
        LineFeed2 = LineFeed2.substring(IndexOf("$")+1);
        Output += ("Value (Rs.) "
                  + LineFeed2.substring(0,LineFeed2.IndexOf("$")+"\n"+"\n"));
        LineFeed2 = LineFeed2.substring(IndexOf("$")+1);
        } catch (Exception A){
        System.out.println("Error in Line Number: " + ptr+1);}
LineFeed2 = LineFeed2.substring(4); //removing the null =)
//Adding the Last Line
LineFeed2 = LineFeed2.substring(IndexOf("$")+1);
Output += ("Gross Total " + LineFeed2.substring(0,LineFeed2.IndexOf("$")));
LineFeed2 = LineFeed2.substring(IndexOf("$")+1);
Output += ("Tax Amount of Rs "
          + LineFeed2.substring(0,LineFeed2.IndexOf("$")));
LineFeed2 = LineFeed2.substring(IndexOf("$")+1);
Output +=( "Total Invoice Value "
          + LineFeed2.substring(0,LineFeed2.IndexOf("$")));
LineFeed2 = (LineFeed2.substring(IndexOf("$")+1));
//Here is the output you Desire
System.out.println(Output);
}I think a simplier approach is to add a Delimeter. Then Cut the substring before the Delimeter. You can also check if there is a missing part in the line by counting the delimeters. Here is my suggestion.
S.No Description Qty. Units Rate (Rs.) Value (Rs.)
1$Aviation Lamp$1$Nos$3700$3,700$
2$Lighting Arrester$1$Nos$1600$1,600$
3$Aviataion Lamp Cable$31$Rmt$270$8,370$
Gross Total $13,670$
The above Total include Services Tax Amount of Rs $536$
Total Invoice Value $13,670$
thats how should it look. You can change the '$' sign if you like.
Then, extract all the content of the file into a single String.
i am unable to process it...can any one give me idea where i went wrong??
