Wrap all the text in single line. Split first by ;. Foreach collection item, split by , and fill the values.

Sample parsing in Java:

import java.io.*;
import java.util.*;

public class EmployeeParse {
	
	private Integer empID ;
	private String empName ;
	private String empCity ;
	
	
	public Integer getEmpID() {
		return empID;
	}

	public void setEmpID(Integer empID) {
		this.empID = empID;
	}

	public String getEmpName() {
		return empName;
	}

	public void setEmpName(String empName) {
		this.empName = empName;
	}

	public String getEmpCity() {
		return empCity;
	}

	public void setEmpCity(String empCity) {
		this.empCity = empCity;
	}

	
	public EmployeeParse() {
	}

	public static void main(String[] args) {
		try {
			ArrayList<EmployeeParse> empList = new ArrayList<EmployeeParse>() ;
		    File file = new File ( "/Users/ramesh/Documents/workspace/Programs/src/employee.rtf") ;
		    
		    if ( file.exists() )   
		    {  
		    	Scanner inFile = new Scanner( file );
		    	inFile.useDelimiter("[;]");
		        while ( inFile.hasNext() )
		        {
		        	String line = inFile.next() ;
		            line = line.trim().replaceAll("\n", "");
		            line = line.trim().replaceAll("\t", "");

		            if ( line.length() > 0 ) {
		            	String delims = "[,]+";
		            	String[] tokens = line.split(delims);
		            	EmployeeParse emp = new EmployeeParse() ;
		            	emp.setEmpID(Integer.parseInt(tokens[0]));		            	
		            	emp.setEmpName(tokens[1]);
		            	emp.setEmpCity(tokens[2]);
		            	
		            	empList.add(emp) ;
		            }
		        }

		        inFile.close(); 
		        
		    }
			else {
				System.out.println( "File Not Found");
			}
		    Integer rec = 0 ;
		    for (EmployeeParse employee : empList) {
		    	System.out.println( "Employee-"+ ++rec +":");
				System.out.println( "ID = " + employee.getEmpID());
				System.out.println( "Name = " + employee.getEmpName());
				System.out.println( "City = " + employee.getEmpCity());
			}
		}
		catch ( FileNotFoundException e) {
			System.out.println( "File Not Found Exception");
		}
	
	}

}

Output:

Employee-1:
ID = 101

City = city1

ID = 2
Name = emp2
City = city2

ID = 3

City = city4
Employee-5:
ID = 5
