How to specify pairs of variabel names and values in OdiInvoke

Question

Hi,
If you start the scenario from a web service, you are invoking the service OdiInvoke. When you look at the WSDL for this Web Service, you will notice that beyond the scenario name, version and the execution context, you can specify pairs of variable names and values. The WSDL for the web service as following:
<xsd:complexType name="SessionRequestType">
<xsd:sequence>
<xsd:element minOccurs="0" default="true" type="xsd:boolean" name="Synchronous"/>
<xsd:element minOccurs="1" type="xsd:long" name="SessionId"/>
<xsd:element minOccurs="0" default="true" type="xsd:boolean" name="KeepVariables"/>
<xsd:element minOccurs="0" type="VariableType" name="Variables" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="VariableType">
<xsd:all>
<xsd:element type="xsd:string" name="Name"/>
<xsd:element type="xsd:string" name="Value"/>
</xsd:all>
</xsd:complexType>..........
If i call this OdiInvoke web service from BPEL, From BPEL assign activity, how can i specify pairs of variable names and values? Example: i have variable 1 and value1, variable 2 and value2, how to assign them to pairs if variable names and values. so that after the assignment, the payload for assign activity in BPEL can be become as following:
<Variables>
<Name>variable1</Name>
<Value>value1</Value>
<Name>variable2</Name>
<Value>value2</Value>
</Variables>
Thanks!

Try this way,
In the expression builder copy the xml fragment to the target node. This will result in the below assign action in the bpel code
<assign name="Assign1">
<copy>
<from expression="&lt;Variables>&lt;Name>variable1&lt;/Name>&lt;Value>value1&lt;/Value>&lt;Name>variable2&lt;/Name>&lt;Value>value2&lt;/Value>&lt;/Variables>"/>
<to variable="outputVaribable"/>
</copy>
</assign>
