I have a problem with using the SAX parser to parse a XML file. It is a complex XML file, it is like the following.

    <Objects>
        <Object no="1">
            <field name="PID">ilives:87877</field>
            <field name="dc.coverage">Charlottetown</field>
            <field name="fgs.ownerId">fedoraAdmin</field> 
        </Object>
        <Object no="2">......

I am confused how to get the names in each field, and how to store the information of each object.

import java.util.Enumeration;
import java.util.Hashtable;


public class XMLObject {
 private Hashtable mFields = new Hashtable();
    private int mN = -1;
    public int getN() {
        return mN;
    }
    public void setN(int n) {
        mN = n;
    }
    public String getStringField(String key) {
        return (String) mFields.get(key);
    }
    public void setStringField(String key, String value)
    {
        mFields.put(key, value);
    }
    public String getPID() {
        return getStringField("PID");
    }
    public void setPID(String pid) {
        setStringField("PID", pid);
    }
    public String getDcCoverage() {
        return getStringField("dc.coverage");
    }
    public void setDcCoverage(String dcCoverage) {      
        setStringField("dc.coverage", dcCoverage);
    }
    public String getFgsOwnerId() {
        return getStringField("fgs.ownerId");
    }
    public void setFgsOwnerId(String fgsOwnerId) {
        setStringField("fgs.ownerId", fgsOwnerId);
    }
    public String dccreator() {
        return getStringField("dc.creator");
    }
    public void dccreator(String dccreator) {
        setStringField("dc.creator", dccreator);
    }
    public String getdcformat() {
        return getStringField("dc.format");
    }
    public void setdcformat(String dcformat) {
        setStringField("dc.format", dcformat);
    }
    public String getdcidentifier() {
        return getStringField("dc.identifier");
    }
    public void setdcidentifier(String dcidentifier) {
        setStringField("dc.identifier", dcidentifier);
    }
    public String getdclanguage() {
        return getStringField("dc.language");
    }
    public void setdclanguage(String dclanguage) {
        setStringField("dc.language", dclanguage);
    }
    public String getdcpublisher()
    {
        return getStringField("dc.publisher");
    }
    public void setdcpublisher(String dcpublisher)
    {
        setStringField("dc.publisher",dcpublisher);
    }
    public String getdcsubject()
    {
        return getStringField("dc.subject");
    }
    public void setdcsubject(String dcsubject)
    {
        setStringField("dc.subject",dcsubject);
    }
    public String getdctitle()
    {
        return getStringField("dc.title");
    }
    public void setdctitle(String dctitle)
    {
        setStringField("dc.title",dctitle);
    }
    public String getdctype()
    {
        return getStringField("dc.type");
    }
    public void setdctype(String dctype)
    {
        setStringField("dc.type",dctype);
    }


    public String toString() {
        StringBuffer sb = new StringBuffer();
        sb.append("N:"+mN+";");
        Enumeration keys = mFields.keys();
        while (keys.hasMoreElements()) {
            String key = (String) keys.nextElement();
            sb.append(key+":"+mFields.get(key)+";");
        }
        return sb.toString();
    }

} i used the same handler class you provided
