How do I  read data from a read.xml file and store it in a String variable sGroup in a CrewingGroup.java file .

I need to find - 'ost' from - <connection-name>ost</connection-name> in read.xml and
Store it in a variable sGroup in CrewingGroup.java  and use sGroup whereever I have 'ost' hard-coded in the java file.

Example:   'gr-ost' should be 'gr- +  sGroup + "'" // something like that ??

Please provide suggestions on how to do this ..?

Eagerly awaiting suggestions ....
File - read.xml
<?xml version="1.0" encoding="UTF-8"?>


File: CrewingGroup.java
import java.sql.*;
import java.lang.*;
import java.io.*;

public class CrewingGroup {

      public static void main (String[] args) throws SQLException, ClassNotFoundException {
             String s_name = "TEST";
            Class.forName ( "oracle.jdbc.driver.OracleDriver" );
            Connection conn = DriverManager.getConnection("jdbc:oracle:oci:@devspi", "scott", "tigre");
            Statement stmt = conn.createStatement();
            ResultSet rs = stmt.executeQuery ("select e.str_email1, ge.str_comment from  contact.groups g WHERE  ge.pk_entity = e.pk_entity AND g.str_name = 'gr-ost' ");
            try {
                  FileOutputStream f = null;
                  PrintStream pf = null;
                  f = new FileOutputStream("output.txt");
                  pf = new PrintStream(f);
                  pf.println ("<OrganiseUsers> <sync />");
                  while (rs.next()) {
                        String name = rs.getString(1);
                        s_name = name;
                        String comment = rs.getString(2);
                        System.out.println ("Name : " + name);
                        System.out.println ("Comment : " + comment );
      pf.println ("<move source=\"Users\\LDAP Users\\" + s_name + "\" target=\"Users\\gr-ost\" />");
                  } // end while
                  pf.println ("</OrganiseUsers>");
                  pf.close(); // close and free up system resource.
                  f.close(); // close in reverse order;FileOutputStream last
      } catch (Throwable t) {}
    } // end main()

you need to parse xml document using SAX or DOM apis.
if you have Jdk 1.3 or higher, then there will be a package of org.
import that package in ur project.
By using DOM u can easily navigate to each node of xml, and get ur desired data.
