Error: The result is empty for XPath expression

Question

hi gurus
Following is my input sample data to BPEL process.
<ItemList>
<Item>
<Name>Music System</Name>
<Id>525</Id>
<Item>
<Name>Fog Light</Name>
<Id>325</Id>
<Item>
<Name>Tyres</Name>
<Id>325</Id>
<Item>
<Name>Neon Light Ring</Name>
<Id>325</Id>
</Item>
</Item>
</Item>
</Item>
</ItemList>
Here <ItemList> contains <Item>.
And <Item> contains <Name>,<Id> & <Item> element itself.
i have created proper XSD for this.
But When i try to fetch any value then using Assign Activityits gives runtime following error.
Error in evaluate from expression at line "36".The result is empty for the XPATH expression: /ns1:ItemList/ns1:Item/ns1:Name
Any suggestion..?
thanks

Here is my XSD.
<?xml version="1.0" encoding="windows-1252"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.example.org"
targetNamespace="http://www.example.org"
elementFormDefault="qualified" >
<xsd:element name="ItemList" type="ItemListType"/>
<xsd:element name="Total" type="TotalType"/>
<xsd:complexType name="ItemListType">
<xsd:sequence>
<xsd:element name="Item" type="ItemType"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="ItemType">
<xsd:sequence>
<xsd:element name="Name" type="xsd:string"/>
<xsd:element name="Id" type="xsd:string"/>
<xsd:element name="Item" type="ItemType"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="TotalType">
<xsd:sequence>
<xsd:element name="TotalPrice" type="xsd:double"/>
</xsd:sequence>
</xsd:complexType>
