Update statement problem !!

Question

Hi,
I need some specific features for my school project and BDB is almost providing me with this functionality. In my project, I want to provide the user with the functionality to provide the update statements from the user screen. I want to then take the user input in a java variable for manipulation of the xml data and display the end result. The only option I have for the user is to provide the xquery updates with the following syntax: ( I need this syntax for update statements as I use a parser to convert the user input to involve fuzziness):
"insert nodes <b4>inserted child</b4> after doc('dbxml:/test.dbxml/book)/Bookstore";
Now I am trying to run these with the below Code but I am not actually getting the required output. Can somebody help me to debug or fix this code for my requirement. I use the following xml data :
<Bookstore>
<Book>
<book_ID>1</book_ID>
<title>Harry Potter and the Order of the Phoenix</title>
<subtitle/>
<author>
<author_fname>J.K.</author_fname>
<author_lname>Rowling</author_lname>
</author>
<price>9.99<;;/price>
<year_published>2004</year_published>
<publisher>Scholastic, Inc.</publisher>
<genre>Fiction</genre>
<quantity_in_stock>28997</quantity_in_stock>
<popularity>20564</popularity>
</Book>
</Bookstore>
I have track points in my code to find the mistake and I get the following ouput.
Track 3
Track 3.1
Track 3.2-----
The code I use fails to compile the xquery statement with .prepare API.
import java.io.*;
import com.sleepycat.db.*;
import com.sleepycat.dbxml.*;
public class phone{
public static void main(String[] args)
String document1 = "C:/Documents and Settings/cjmadall/Desktop/BDB/book.xml";
String docName = "book";
XmlManager myManager = null;
XmlContainer myContainer = null;
try {
myManager = new XmlManager();
myContainer = myManager.openContainer("test.dbxml");
String myQuery = "insert nodes <b4>inserted child</b4> after doc('dbxml:/test.dbxml/book)/Bookstore";
// This Works and displays the entire document-> String myQuery = "collection('test.dbxml')";
// This Doesnt Work, ends with the above output -> String myQuery = "insert nodes <newNode>Some new text</newNode> after collection("dbxml:/test.dbxml")/Bookstore";
// collection('test.dbxml')/Bookstore";
System.out.println("Track 3 ");
XmlQueryContext managerContext = myManager.createQueryContext();
System.out.println("Track 3.1 ");
// Get a context for the document queries
// XmlQueryContext documentContext = myManager.createQueryContext();
System.out.println("Track 3.2 ");
// Prepare the XmlManager query
*XmlQueryExpression managerQuery = myManager.prepare(myQuery, managerContext);*
System.out.println("Track 3.3 ");
// Perform the query.
XmlResults results = managerQuery.execute(managerContext, 0);
// Display the result set
System.out.println("Track 3.4 ");
XmlValue value;
while ((value = results.next()) != null){
System.out.println(value.asString());
System.out.println("Track 3.5 ");
results.delete();
managerQuery.delete();
// documentContext.delete();
managerContext.delete();
} catch (XmlException e) {
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
if (myContainer != null) {
myContainer.close();
if (myManager != null) {
myManager.close();
} catch (XmlException ce) {
// Exception handling goes here
}//end finally
Thanks.

I was using a old version of BDB and the latest version fixed this issue.
