[ketandba]

hi,
This is my code.....
************************
public class InvoiceNotesHandler extends DefaultHandler {
private String currentElement = null; // State variable
private String currentQname = null;

String dateString = null;
String descriptionString = null;
String minutesString = null;

StringBuffer thisText = new StringBuffer();

static Hashtable clientNameToRecords;
String clientName = null;

float hours = 0;
ArrayList clientList = new ArrayList();

public void startDocument() {
clientNameToRecords = new Hashtable();
}
public void endDocument() {

}
public void startElement( String uri,
String localname,
String qname,
Attributes attributes)
throws SAXException {

if(qname.equals("client")) {

currentQname = qname;
clientName = attributes.getValue(0);
}

else if(qname.equals("REC")) {

currentQname = qname;
}

currentQname = qname;
}

public void endElement(String uri,
String localname,
String qname)
throws SAXException {
if (thisText.length() > 0) {

if(qname.equals("DATE1"))
{

dateString = thisText.toString().trim();

}
else if(qname.equals("DESCRIPTION"))
{
descriptionString = thisText.toString().trim();

}
else if(qname.equals("MINUTES"))
{
minutesString = thisText.toString().trim();
hours = new Float(minutesString).floatValue();

}else if(qname.equals("REC"))
{

Record record = new Record(dateString, descriptionString, hours);
clientList.add(record);
}
thisText.delete(0, thisText.length());
}

if(qname.equals("client")){

clientNameToRecords.put(clientName, clientList);
System.out.print(clientNameToRecords);
clientList.clear();

}
thisText.delete(0, thisText.length());
}

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

thisText.append(ch, start, length);

}
}
******************************
My input xml file..

i want to print the hashtable contents as

{"A"=[010104aaaaaaa0.30,010204bbbbbbb0.50]}
{"B"=[010104cccccc0.70,010804ddddd0.30,010904eee0.25]}
{"C"=[011104xxxx0.70,010504yyyy0.60,010404zzzz0.25]}

but my code give me the output like this..(WRONG)
{"A"=[010104aaaaaaa0.30,010204bbbbbbb0.50]}

{"B"=[010104cccccc0.70,010804ddddd0.30,010904eee0.25],"A"=[010104cccccc0.70,010804ddddd0.30,010904eee0.25]}

{"B"=[011104xxxx0.70,010504yyyy0.60,010404zzzz0.25],"C"=[011104xxxx0.70,010504yyyy0.60,010404zzzz0.25],"A"=[011104xxxx0.70,010504yyyy0.60,010404zzzz0.25]}
