XMLTYPE variable converting to XML (Question)

Question

Friends,
I am stuck on an error and cannot find a way out. Please help. I know it's a long question but a very simple answer to many smart people here. I am just lost and need your help. (I am new to SOA so bear with me)
I have a BPEL process which invokes a PL/SQL API which returns the XMLTYPE output which has the XML data. In order to convert the XMLTYPE to normal XML I do following :-
- I added a Java embed activity in BPEL with following code (Invoke_new_get_customer_order_info_OutputVariable','OutputParameters','/ns2:OutputParameters/ns2:X_CUSTOMER_ORDER_INFO_XML is the XMLTYPE)
(responsePayoad is string variable)
try{                                                           
Node node = (Node)getVariableData("Invoke_new_get_customer_order_info_OutputVariable','OutputParameters','/ns2:OutputParameters/ns2:X_CUSTOMER_ORDER_INFO_XML");
Node childNode = (Node) node.getFirstChild();
StringWriter writer = new StringWriter();
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.transform(new DOMSource(childNode), new StreamResult(writer));
String xml = writer.toString();
String nsXML = xml.replaceFirst("<FetchCustomerInfoResponse","<FetchCustomerInfoResponse xmlns=\"http://xmlns.djoglobal.com/OrderTracking/CustomerInfo\" ");
setVariableData("responsePayload",nsXML);
addAuditTrailEntry("XML with Namespace: " + nsXML);
} catch(Exception e){                            
addAuditTrailEntry(e);
System.out.println("Namespace injection failed due to : " + e);
After above I have ASSIGN activity where I use parsexml function on the "responsePayload" variable to assign to a variable of type element which refers to following xsd. This is where I get an "internal xpath error" during runtime which I cannot resolve.
XSD of the element variable refering to "FetchCustomerInfoResponse" element
<?xml version="1.0" encoding="windows-1252" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.example.org"
targetNamespace="http://xmlns.djoglobal.com/OrderTracking/DJOFetchCustomerOrderInfo"
elementFormDefault="qualified">
<xsd:element name="FetchCustomerInfoResponse">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="DJO_ONT_ACCOUNT_ORDERS">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="DJO_ONT_ACCOUNT_ORDER" maxOccurs="unbounded">

</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
XML returned in the XMLTYPE from the PL/SQL API :-
<Invoke_new_get_customer_order_info_OutputVariable><part name="OutputParameters" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<OutputParameters xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.oracle.com/pcbpel/adapter/db/APPS/XXDJO_ONT_ORDER_TRACKING_WS/GET_CUSTOMER_ORDER_INFO_XML/"><X_CUSTOMER_ORDER_INFO_XML>
<FetchCustomerInfoResponse xmlns="">

</FetchCustomerInfoResponse>
</X_CUSTOMER_ORDER_INFO_XML>
</OutputParameters></part></Invoke_new_get_customer_order_info_OutputVariable></messages>
Any help is greatly appreciated as this is driving me nuts.
Thanks

Few modifications,
1. Initialize your int count to 0, int count=0;
2. Write count++; as the first statement in your for loop. 3. Remove count++; at the bottom.
4. Add a hidden field to your form (after submit button, but before your </form> tag)
<input type="hidden" name="qCount" value="<%=count%>">
Now use this code,
writeXML.jsp
<%
int qCount = Integer.parseInt(request.getParameter("qCount"));
String home ="C:\\Tomcat\\FYProject\\lib\\";
String filename = request.getParameter("file");
String extension = ".xml";
String filePath = home + filename + extension;
BufferedWriter bw = new BufferedWriter(new FileWriter(filePath,true));
bw.write("<mc_QuestionType>");
bw.newLine();
for(int count=0;count<qCount;count++) {
     String Tquestion = request.getParameter("questionText"+count);
     String answer1 = request.getParameter("choice_1"+count);
     String answer2 = request.getParameter("choice_2"+count);
     String answer3 = request.getParameter("choice_3"+count);
     String answer4 = request.getParameter("choice_4"+count);
     String Canswer = request.getParameter("cAnswer"+count);
     bw.write(" <questionText>" Tquestion "</questionText>");
     bw.newLine();
     bw.write(" <choice>" answer1 "</choice>");
     bw.newLine();
     bw.write(" <choice>" answer2 "</choice>");
     bw.newLine();
     bw.write(" <choice>" answer3 "</choice>");
     bw.newLine();
     bw.write(" <choice>" answer4 "</choice><br>");
     bw.newLine();
     bw.newLine();
     bw.write(" <answer>" Canswer "</answer>");
     bw.newLine();
     bw.write("</mc_QuestionType>");
     bw.close();
%>Hope this works.
