Problems to read out an XML

Question

Hello together
I have a problem to read out an XML file with JDOM. I am in charge to read out one attribute of the XML with JDOM. But my XML file has more than one Attribute of the same type. It is repeated more than once... It looks like that...
<Resolution v="PT15M"/>
               <Interval>
                    <Pos v="1"/>
                    <Qty v="0"/>
               </Interval>
               <Interval>
                    <Pos v="2"/>
                    <Qty v="0"/>
               </Interval>
               <Interval>
                    <Pos v="3"/>
                    <Qty v="0.379"/>
               </Interval>
               <Interval>
                    <Pos v="4"/>
                    <Qty v="2.453"/>
               </Interval>
               <Interval>
                    <Pos v="5"/>
                    <Qty v="0"/>
               </Interval>
               <Interval>
                    <Pos v="6"/>
                    <Qty v="0"/>
               </Interval>
               <Interval>
                    <Pos v="7"/>
                    <Qty v="1.108"/>
               </Interval>
               <Interval>
                    <Pos v="8"/>
                    <Qty v="2.22"/>
               </Interval>
               <Interval>
                    <Pos v="9"/>
                    <Qty v="0"/>
               </Interval>
               <Interval>
                    <Pos v="10"/>
                    <Qty v="0.247"/>
               </Interval>
               <Interval>
                    <Pos v="11"/>
                    <Qty v="0.712"/>
               </Interval>
               <Interval>
                    <Pos v="12"/>
                    <Qty v="0.964"/>
               </Interval>
Now, I want to read out the Qty from 1 to 6 and I tried it now with an Iterator but it doesn't work...I don't know what the problem is, so please help me...
I also post the Java File here. I am sorry for y English..

Hello together
I have a problem to read out an XML file with JDOM. I am in charge to read out one attribute of the XML with JDOM. But my XML file has more than one Attribute of the same type. It is repeated more than once... It looks like that...
<Resolution v="PT15M"/>
<Interval>
<Pos v="1"/>
<Qty v="0"/>
</Interval>
<Interval>
<Pos v="2"/>
<Qty v="0"/>
</Interval>
<Interval>
<Pos v="3"/>
<Qty v="0.379"/>
</Interval>
<Interval>
<Pos v="4"/>
<Qty v="2.453"/>
</Interval>
<Interval>
<Pos v="5"/>
<Qty v="0"/>
</Interval>
<Interval>
<Pos v="6"/>
<Qty v="0"/>

<Pos v="7"/>
<Qty v="1.108"/>
</Interval>
<Interval>
<Pos v="8"/>
<Qty v="2.22"/>
</Interval>
<Interval>
<Pos v="9"/>
<Qty v="0"/>
</Interval>
<Interval>
<Pos v="10"/>
<Qty v="0.247"/>
</Interval>
<Interval>
<Pos v="11"/>
<Qty v="0.712"/>
</Interval>
<Interval>
<Pos v="12"/>
<Qty v="0.964"/>
</Interval>
Now, I want to read out the Qty from 1 to 6 and I tried it now with an Iterator but it doesn't work...I don't know what the problem is, so please help me...
The problem is, that the Iterator doesn't bring out my Quantity Attribute (see part of the xml above). I didn't get any error messages, so I really don't know what the problem is. I am a beginner, so maybe you can help me...
I also post the Java File here. I am sorry for my English..
               /*Elemente holen*/
               //4. Stufe
               // Childs von period auslesen
               Element timeinterval = period.getChild("TimeInterval");
               Element resolution = period.getChild("Resolution");
               Element interval = period.getChild("Interval");
               //5. Stufe
               // Childs von interval auslesen
               Element position = interval.getChild("Pos");
               Element quantity = interval.getChild("Qty");
               /*Attribute holen*/
               //Attribute aus Stufe 4 auslesen (aus XML)
               String timeintervalv = timeinterval.getAttributeValue ("v");
               String resolutionv = resolution.getAttributeValue ("v");
               //Attribute aus Stufe 5 auslesen (aus XML)
               Iterator i = period.getChildren("Interval").iterator();
               while(i.hasNext()) {
               Element currentElement = (Element)i.next();
               Iterator j = currentElement.getAttributes().iterator();
               System.out.print(j);
               while(j.hasNext()) {
                    Attribute currentAttribute = (Attribute)j.next();
               System.out.println("Attribute\t Name: "+currentAttribute.getName()+", Value: "+currentAttribute.getValue());
               String positionv = position.getAttributeValue ("v");
               String quantityv = quantity.getAttributeValue ("v");
Thank you for your help....
