Parsing XML: PHP vs Java

Let's see how much time does PHP programmer spend to parse some XML file.

Here is our test XML file:

and this is how I would parse this document in PHP:

and the result would be:

 

Nice, don't you think?

And this is how I would parse the same file in Java:

Main.java:

package me.tcom.kdarko.blog;

import java.io.IOException;
import java.util.ArrayList;
import org.xml.sax.SAXException;

public class Main
{
   
    private ArrayList arraylist = null ;
   
    public static void main(String[] args)
    {
    try {
        Main m = new Main();
        m.arraylist = new EmployeesListParser("list_of_employees.xml").doParse();
        for(Employee e:m.arraylist)
        System.out.println("Employee: ID: " + e.getId() + " , " + e.getName() + "  " + e.getLast_name());       
        }
        catch (IOException ex)
        {
        System.out.println(ex.getMessage());
        }
        catch (SAXException ex)
        {
        System.out.println(ex.getMessage());
        }
        catch (Exception ex)
        {
        System.out.println(ex.getMessage());
        } 
    }

}

Employee.java:

package me.tcom.kdarko.blog;

public class Employee
{

    String id , name, last_name;

    public Employee() {
    }
  
    public Employee(String id, String name, String last_name) {
        this.id = id;
        this.name = name;
        this.last_name = last_name;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getLast_name() {
        return last_name;
    }

    public void setLast_name(String last_name) {
        this.last_name = last_name;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
       
}

EmployeesListParser.java:

package me.tcom.kdarko.blog;

import java.io.IOException;
import java.util.ArrayList;
import org.xml.sax.Attributes;
import org.xml.sax.ContentHandler;
import org.xml.sax.Locator;
import org.xml.sax.SAXException;
import org.xml.sax.XMLReader;
import com.sun.org.apache.xerces.internal.parsers.SAXParser;

public class EmployeesListParser implements ContentHandler
{
    private String XML_FILE_NAME;
    String temp = null;
    Employee employee = new Employee();
    StringBuffer sb=new StringBuffer();
    private ArrayList arraylist = new ArrayList();

    public EmployeesListParser(String XML_FILE_NAME) {
        this.XML_FILE_NAME = XML_FILE_NAME;
    }
   
    public ArrayList doParse() throws IOException, SAXException
    {
     XMLReader parser = new SAXParser();
     parser.setContentHandler(this);
     parser.parse(XML_FILE_NAME);
     return arraylist;  
    }

    public void startElement(String uri, String name, String qName, Attributes atts) throws SAXException
    {
         sb.setLength(0);
         if(name.equalsIgnoreCase("id"))
             temp="id";
         else if(name.equalsIgnoreCase("name"))
             temp="name";
         else if(name.equalsIgnoreCase("last_name"))
             temp = "last_name";
         else if(name.equalsIgnoreCase("employee"))
          employee = new Employee();
    }

    public void endElement(String uri, String name, String qName) throws SAXException
    {
    sb.setLength(0);
    if(name.equalsIgnoreCase("employee"))
    {
     arraylist.add(employee);
     employee=null;
    }
    }

    public void characters(char[] arg0, int arg1, int arg2) throws SAXException
    {
        sb.append(arg0,arg1,arg2);
        String s = sb.toString().trim();
        if(!s.equals(""))
        {
        if( temp.equalsIgnoreCase("id") )
        {
         employee.setId( s );
        }
        else if( temp.equalsIgnoreCase("name") )
        {
        employee.setName( s );
         }
         else if( temp.equalsIgnoreCase("last_name") )
         {
        employee.setLast_name(s);
         }
    }
    }

    public void setDocumentLocator(Locator locator) {
    }

    public void startDocument() throws SAXException {
    }

    public void endDocument() throws SAXException {
    }

    public void startPrefixMapping(String prefix, String uri) throws SAXException {
    }

    public void endPrefixMapping(String prefix) throws SAXException {
    }

    public void ignorableWhitespace(char[] ch, int start, int length) throws SAXException {
    }

    public void processingInstruction(String target, String data) throws SAXException {
    }

    public void skippedEntity(String name) throws SAXException {
    }
   
}
 

and the result would be:
