did you already tried Oracle's xml libraries (you can get them at
your code may look like this:
// Construct the new XML Document.
XMLDocument xmlDoc = new XMLDocument() ;
// Create the root Node.
XMLNode rootNode = (XMLNode) xmlDoc.createElement("ROOT") ;
// Create a new node.
XMLNode node = (XMLNode) xmlDoc.createElement("TAG") ;
// Add text to the new node.
node.appendChild(new XMLText("Value")) ;
// Append a child to the root tag.
/* Repeat the above statements as much as needed (you could make
this recursive in order to create child and/or parent tags.
// Append the complete root node (tree) to the new XMLDocument.
