DVM with OSB

Question

Hi All,
Wanted to implement DVM with OSB.
Follwed the below URL and tried to implement as is.
https://blogs.oracle.com/christomkins/entry/domain_value_maps_in_oracle_se
Created project, created XQuery with DVM information, created XQuery to get those values from DVM.
But when i run iam getting the following error message
Error Message:
<error>Error occurred while executing XQuery: line 10, column 9: {err}FORG0005: expected exactly one item, got 0 items. Either the XQuery is invalid or it contains custom XQuery functions. Try using the web test console to test this XQuery (Right click on the XQuery file and select Run As ->Run On Server) </error>
The below line is creating problem:
*$dvm/ns0:rows/ns0:row[ns0:cell[1]=$airportName]/ns0:cell[2]* - This xpath is throwing the exception.
Thanks,
Vijay

Thanks Vlad for your response, I have pasted below the DVM file.
+<dvm name="airportCodes" xmlns="http://xmlns.oracle.com/dvm">+
+<description>This is description</description>+
+<columns>+
+<column name="Airport Name"/>+
+<column name="Airport Code"/>+
+</columns>+
+<rows>+
+<row>+
+<cell>London Heathrow</cell>+
+<cell>LHR</cell>+
+</row>+
+<row>+
+<cell>Dublin</cell>+
+<cell>DUB</cell>+
+</row>+
+<row>+
+<cell>Liverpool</cell>+
+<cell>LIV</cell>+
+</row>+
+</rows>+
+</dvm>+
and i have the standard dvm.xsd file as schema file.
This below Xquery is used, to get the value from above DVM file.
+(:: pragma bea:global-element-parameter parameter="$dvm" element="ns0:dvm" location="dvm.xsd" ::)+
declare namespace ns2 = "";
declare namespace ns0 = "http://xmlns.oracle.com/dvm";
declare namespace xf = "http://tempuri.org/SimpleOSBv1/SimpleDVM/";
declare function xf:SimpleDVM($dvm as element(ns0:dvm),
+$airportName as xs:string)+
+as xs:string {+
+$dvm/ns0:rows/ns0:row/ns0:cell[1]+
+};+
declare variable $dvm as element(ns0:dvm) external;
declare variable $airportName as xs:string external;
xf:SimpleDVM($dvm,
+$airportName)+
Thanks,
Vijay
