Hi,

I have some problems by getting the attributes from the first child node, if i try to get child elements everything works fine, but whenever i need the elementvalue from a node with attributes i doesn't return anything.
The xpath expression works fine if i want to get the element value from all childs, but not when i just want from one of them.

This one works,

XPathFactory factory1 = XPathFactory.newInstance();
    XPath xpath = factory1.newXPath();
    xpath.setNamespaceContext(new PersonalNamespaceContext());
    XPathExpression expr 
     = xpath.compile("//default:DeviceExchange[1]/default:Status/text()");
   
   // gets the value of the node picked out
    Object result = expr.evaluate(doc, XPathConstants.NODESET);
    NodeList nodes = (NodeList) result;
    for (int i = 0; i < nodes.getLength(); i++) {
      names[i] = nodes.item(i).getNodeValue();
      String a = names;

// checks if status is exchanged, if it is sets status to 1

if (a.length() == 9){

names[i] = "1"; }

else{  names[i] = "0";}

System.out.println(names[i]);
This doesn't
XPathFactory factory2 = XPathFactory.newInstance();

XPath xpath2 = factory2.newXPath();

xpath2.setNamespaceContext(new PersonalNamespaceContext());

XPathExpression expr2 = xpath2.compile("//default:DeviceExchange[1]/default:Field[@names='MLPKTID']/text()");



Object result2 = expr2.evaluate(doc, XPathConstants.NODESET);

NodeList nodes2 = (NodeList) result2;

for (int i = 0; i < nodes2.getLength(); i++) {

names2[i] = nodes2.item(i).getNodeValue();

System.out.println(names2[i]);}
Does anyone have any ideas? I will apreciate all help!
