[JAVA] Problema con vector.addElement(Object)

[xxdavide84xx]

Salve.

Io ho una
class Body {
String stile;

String jc;

String grassetto;

String italico;

String testo;

public String toString() {
StringBuffer buffer = new StringBuffer();
if ( stile != null )
buffer.append("Stile body: " + stile + "\n");
if ( jc != null )
if ( grassetto != null )
buffer.append(" Grassetto body " + grassetto + "\n");
if ( italico != null )
buffer.append(" Italico body " + italico + "\n");
buffer.append(" Testo body: " + testo + "\n");
return buffer.toString();
}
}

con questo funzione il problema è bodyObjects.addElement(body); che mi memorizza sempre lo stesso NODO...
cerco di spiegarmi meglio io per es ho:
w:p
w:rPr 1
w:r ciao
w:r Gino
w:p
w:rPr 2
w:r come
w:r stai
w:r ?
e al posto che restituirmi come sopra il mio programma restituisce:
w:p
w:rPr 1 w:r ciao
w:rPr 1 w:r ciao
w:p
w:rPr 2 w:r come
w:rPr 2 w:r come
w:rPr 2 w:r come
il pezzo in cui penso sia il problema:
private void createBodyObjects() {
for ( int i = 0; i < bodyNodes.size(); i++) {
Node bodyNode = (Node)bodyNodes.elementAt(i);
Body body = new Body();
Node paragraphNode = getChildNode(bodyNode, "w:pPr");
if ( paragraphNode != null ) {
Node stileNode = getChildNode(paragraphNode, "w:pStyle");
if ( stileNode != null )
body.stile = getAttributeValue(stileNode, "w:val");
Node jcNode = getChildNode(paragraphNode, "w:jc");
if ( jcNode != null )
body.jc = getAttributeValue(jcNode, "w:val");
}
NodeList pNode = getAllChildNode(bodyNode, "w:r");
for ( int j = 0; j < pNode.getLength(); j++) {
Node rNode = (Node)pNode.item(j);
Node rPrNode = getChildNode(rNode, "w:rPr");
if ( rPrNode != null ) {
Node grassettoNode = getChildNode(rPrNode, "w:b");
if ( grassettoNode != null )
body.grassetto = getAttributeValue(grassettoNode, "w:val");
Node italicoNode = getChildNode(rPrNode, "w:i");
if ( italicoNode != null )
body.italico = getAttributeValue(italicoNode, "w:val");
}
Node testoNode = getChildNode(rNode, "w:t");
if ( testoNode != null ) {
Node testoNode1 = getChildNode(testoNode, "#text");
if ( testoNode1 != null )
body.testo = testoNode1.getNodeValue();
}
bodyObjects.addElement(body);
}
}
}

Quello di cui non riesco a capacitarmi è che se scrivo:
System.out.println("A" + body.stile);
System.out.println("B" + body.jc);
System.out.println("C" + body.grassetto);
System.out.println("D" + body.italico);
System.out.println("E" + body.testo);
mi da i valori corretti, ma se metto al posto dei System.out.println bodyObjects.addElement(body);

mi viene preso per TOT di volte sempre lo stesso nodo contentente gli stessi stile,jc,grassetto,italico,testo....

Mi chiedo cosa cambi concettualmente tra il primo e il secondo caso....
