Xml namspace parsing using JDOM

Question

I am trying to read following XML String response using JDOM but have no idea how to parse? can you please help me? I am trying following codes to parse:

org.jdom.Element rootNode =  document.getRootElement();

List<?> list =  rootNode.getChildren("QuotationResponse");
for(int i = 1 ; i <= list.size() ; i++) {
   Element node = (Element) list.get(i);
   String documentDate = node.getAttribute("documentDate");
   String transactionType = node.getAttribute("transactionType");
}

XML:

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

You need to the use Namespace-specific getChildren() method. The Namespace you want is "un:vtinc:o-series:tps:6:0"

Namespace ns = Namespace.getNamespace("un:vtinc:o-series:tps:6:0");
List<?> list = rootNode.getChildren("QuotationResponse", ns);

If you were using JDOM 2.x, the second line could be:

Namespace ns = Namespace.getNamespace("un:vtinc:o-series:tps:6:0");
List<Element> list = rootNode.getChildren("QuotationResponse", ns);

and your whole thing could be:

Namespace ns = Namespace.getNamespace("un:vtinc:o-series:tps:6:0");
for(Element node : rootNode.getChildren("QuotationResponse", ns)) {
  String documentDate = node.getAttribute("documentDate");
  String transactionType = node.getAttribute("transactionType");
}

Edit: OK, you are still having problems. I see a number of things that are wrong now.

You should be using JDOM 2.0.4. It will help with the type-casting. You somehow are putting an Attribute object in to a String. That should not be possible to compile!

String documentDate = node.getAttributeValue("documentđate")

Finally, the QuotationResponse is not a child of the root element, but of the S:Body.... and then VtEncelope. You will need to access these with the right namespaces. You need to get your document structure right.
