Could someone help me out how to insert a Node properly into a DOM?

Question

I am trying to insert a Node built from a String to a DOM.
Here is how I created the Node
               Detail = "<Detail><Msg>Detail Message</Msg></Detail>";
               prolog = "<?xml version="1.0" encoding="UTF-8"?>";
               Node DetailNode = null;
               Document DetailDoc = null;
               if( Detail != null ){
                    Detail = prolog + BiometricDetail;
                    DetailDoc = xp.XML2DOM( BiometricDetail ); // transform a XML String into a DOM.
                    DetailNode = BiometricDetailDoc.getDocumentElement();                    
Here is how I created the DOM
               javax.xml.parsers.DocumentBuilderFactory factory = javax.xml.parsers.DocumentBuilderFactory.newInstance();
               javax.xml.parsers.DocumentBuilder builder = factory.newDocumentBuilder();
               Document document = builder.newDocument();
               Element beeE = document.createElement("BeeSets");
               Element grpE = document.createElement("Group");          
               bioE.appendChild( grpE );
               // the document looks like "<BeeSets><Group></Group><BeeSets>";
               // After inserting the Node DetailNode, I want it to look like
               // "<BeeSets><Group><Detail><Msg>Detail Message</Msg></Detail></Group><BeeSets>";
Now when I tried to insert the node DetailNode to the DOM document, I tried
1) document.importNode( DetailNode, true );               
No exception was thrown. But when I transformed the DOM document back to a String, I could not see the information from the newly imported Node DetailNode.
When I tried
          grpE.insertBefore( BiometricDetailNode, dataE );
I got the following exception.
     org.w3c.dom.DOMException: WRONG_DOCUMENT_ERR: A node is used in a different document than the one that created it.
     at org.apache.xerces.dom.ParentNode.internalInsertBefore(Unknown Source)
     at org.apache.xerces.dom.ParentNode.insertBefore(Unknown Source)
     at com.jadcs.bioidentity.role.base.RP.getNodes(RP.java:497)
2) document.adoptNode( DetailNode );
I got the following exception.
     java.lang.ClassCastException: org.apache.xerces.dom.DocumentImpl
     at org.apache.xerces.dom.DeferredTextImpl.synchronizeData(Unknown Source)
     at org.apache.xerces.dom.NodeImpl.setOwnerDocument(Unknown Source)
     at org.apache.xerces.dom.ParentNode.setOwnerDocument(Unknown Source)
     at org.apache.xerces.dom.ElementImpl.setOwnerDocument(Unknown Source)
     at org.apache.xerces.dom.ParentNode.setOwnerDocument(Unknown Source)
     at org.apache.xerces.dom.ElementImpl.setOwnerDocument(Unknown Source)
     at org.apache.xerces.dom.CoreDocumentImpl.adoptNode(Unknown Source)
     at com.jadcs.bioidentity.role.base.RP.getNodes(RP.java:509)
3) detailStr = "<Detail><Msg>Detail Message</Msg></Detail>";
Element detailE = document.createElement("Detail");
detailE.setTextContent( detailStr );
grpE.appendChild( detailE );
This way gives result like "<BeeSets><Group><Detail><Detail><Flash>On</Flash></Detail></Detail></Group><BeeSets>";
The content is messed up.
Could someone help me out at how to insert a Node properly into a DOM? Thank you very much.

Said another way, importNode actually only makes and returns a copy of the node you gave it (it will be a deep copy only if you pased true as the second parameter), but where the new dom you called import on is owner.
So what you need to do is more like this:
Node tempNode = domYouAreAddingTheNodeTo.importNode(node2copy,true); //true if you want a deep copy
domYouAreAddingTheNodeTo.appendNode(tempNode);You can also traverse to any point in the DOM and insert the node there with the same method, but you always have to import first so that the DOM has a copy of the node that it owns.
