Merging XML Doc's

Question

Hi
I have a servlet that builds up two different connections. The 2 databases holds the same type of data, ie the select statement is the same, it just brings back different time period values. I need to combine these two XML docs into one XML document, massage it a bit, apply style sheet and send to browser.
I have now succeeded in doing the XML doc , massage and sending. However, I'am battling to combine the two xml doc's into one. any help appreciated.
Tks

Here is the Servler code:
String query = queryBuff.toString();
OracleXMLQuery q1 = new OracleXMLQuery(conn1, query);
q1.useLowerCaseTagNames();
q1.setRowsetTag("CARDSLOADED");
q1.setRowTag("CARDREC");
XMLDocument xmldoc1 = (XMLDocument)q1.getXMLDOM();
// now 2nd
OracleXMLQuery q2 = new OracleXMLQuery(conn2, query);
q2.useLowerCaseTagNames();
q2.setRowsetTag("CARDSLOADED");
q2.setRowTag("CARDREC");
XMLDocument xmldoc2 = (XMLDocument)q2.getXMLDOM();
So I need to combine xmldoc1 and xmldoc2. The stylesheet will do the Order by for me.

Hi - got it going ...tks
You need to step down into the XMLDOC to get the nodes and not start at the beginning
Sameple code -
try
String query = queryBuff.toString();
System.out.println("query is >"+query);
OracleXMLQuery q = new OracleXMLQuery(conn2, query);
q.useLowerCaseTagNames();
q.setRowsetTag("CARDSLOADED");
q.setRowTag("CARDREC");
xmldoc2 = (XMLDocument)q.getXMLDOM();
// num_rows = q.getNumRowsProcessed();
} //end try
catch (Exception exc)
out.println(exc.toString());
// Now attemt to merge the two xml docs
try
NodeList list = xmldoc1.getElementsByTagName("CARDSLOADED");
Node root = list.item(0);
NodeList list1 = xmldoc2.getElementsByTagName("CARDREC");
// now loop from pos 0 to end and add each node
int noOfRecs = list1.getLength();
for (int i=1; i <= noOfRecs -1; i++)
Node child=list1.item(i);
Node copy = xmldoc1.importNode(child, true);
root.appendChild(copy);
catch (Exception exc)
System.out.println("Error merging "+exc.toString());
