I am stuck on this issue, and I will happy for answer to next questions:

How I load the .txt file into Java?
After I load the file, how I can acsses to the information into it? for example, How I can asked if the first line of one of the records is equal to "1";
How I export the result to XML's file.

@home: I would like for some highlights how to do it in Java. pseudo code will be excellent. — Adam Sh, Jan 14 '12 at 15:39

Basic I/O
Integer.parseInt(1stLine)
There are a plethora of choices.

one: you need a sample-code for reading a file line by line

two: the split-method of a string might be helpful. For instance getting the number of the first element if information is seperated by a space

String myLine;
String[] components = myLine.split(" ");
if(components != null && components.length >= 1) {
    int num = Integer.parseInt(components[0]);
    ....
}

three: you can just write it like any text-file, or use any XML-Writer you want
