Searching xml, importing found stuff into newDocument

Question

I've an xml file which is structured like
<people>
     <name id="my name">
          <holiday>
               <allocated num="25"/>
               <taken num="0"/>
               <unused num="25"/>
          </holiday>
          <time>
               <admin />
               <marketing />
               <projects />
               <RandD />
               <offSick />
          </time>
     </name>
     <name id="somebody else">
     etc.
</people>I have a user id as a String, for example userID = "my name". Ive read in the file to an object and search through it untill I find a node whose attribute matches the userID. I then want to copy this node, and all of its children into a newDocument called details. This is the code i have at the moment:
//Create a new document
DocumentBuilder domBuilder = newBuilder(false);
Document details = domBuilder.newDocument();
//Get the root Element of timeRecord
Element timeRoot = timeRecord.getDocumentElement();
//Find all Elements with tag name "name"
NodeList nameList = timeRoot.getElementsByTagName("name");
//Step through each of these name Elements
for (int i = 0; i < nameList.getLength(); i++){
     Node nameNode = nameList.item(i);
     //Get the attributes associated with this Element
     NamedNodeMap attributes = nameNode.getAttributes();
     log("NamedNodeMap created");
     Node id = attributes.getNamedItem("id");
     log("got id = attributes.getNamedItem");
     String nameID = id.getNodeValue();
     //Test to see if this Element is the name we are looking for
     //if yes, clone + recursively clone all child nodes
     if (nameID.equals(userID) ){
          Node person = details.importNode(nameNode, true);
          save2File("data", "details.xml", details);
return details;even though it does find the matching attribute, the details document remains empty (if I save it to file using an IDTransform, all I get is the <?xml version="1.0" encoding="UTF-8"?>)
can anyone please help -what do I need to change?

I've searched quite a lot through the forum, and have four thread printed off in front of me. In between them, they've given me enough - didn't really find anything that exactly answered the orriginal question, but, like I said, enough.
//Create a new document
DocumentBuilder domBuilder = newBuilder(false);
Document details = domBuilder.newDocument();
//Get the root Element of timeRecord
Element timeRoot = timeRecord.getDocumentElement();
//Find all Elements with tag name "name"
NodeList nameList = timeRoot.getElementsByTagName("name");
//Step through each of these name Elements
for (int i = 0; i < nameList.getLength(); i++){
     Node nameNode = nameList.item(i);
     //Get the attributes associated with this Element
     NamedNodeMap attributes = nameNode.getAttributes();
     Node id = attributes.getNamedItem("id");
     String nameID = id.getNodeValue();
     //Test to see if this Element is the name we are looking for
     //if yes, clone + recursively clone all child nodes
     if (nameID.equals(userID) ){
          Element foundTag = details.createElement("found");
          details.appendChild(foundTag);
          Node person = details.importNode(nameNode, true);
          Node root = details.getDocumentElement();
          root.appendChild(person);
//If nothing has been found, root will be null, create response telling of error
if (details.getDocumentElement() == null)
     Element errorTag = details.createElement("error");
     details.appendChild(errorTag);
return details;
