There are a sample for loop data out using xpath-querie?

Question

hello,
i have a web service that contains multiple rows. i transfered these data in a variable tInput. Now i want to transfer these data in a output variable.
Is There a sample or tutorial, that shows how to loop data out of a variable (array) in a
second variable using xpath-querie?

Hi,
thanks for the Link, but it doesn't work at all.
I have a variable tOutput with follow content:
tOutput>
<part name="parameters" >
<SchedulForwardResponse>
<SchedulForwardResult>
<ArrayType>
<plnnr>50001203</plnnr>
<vornr>1</vornr>
<starttime>20.08.2006 09:00:00</starttime>
</ArrayType>
<ArrayType>
<plnnr>50001203</plnnr>
<vornr>2</vornr>
<starttime>20.08.2006 09:10:00</starttime>
</ArrayType>
<ArrayType>
<plnnr>50001203</plnnr>
<vornr>3</vornr>
<starttime>20.08.2006 09:35:00</starttime>
</ArrayType>
</SchedulForwardResult>
</SchedulForwardResponse>
</part>
</tOutput>
I want to copy these content in the output Variable of my BPEL Prozess. But just the first <ArrayType> is copy to output:
<ArrayTpe>
<plnnr>50001203</plnnr>
<vornr>1</vornr>
<starttime>20.08.2006 09:00:00</starttime>
</ArrayType>
The other two <ArrayType> fail.
I create 3 variables:
<variable name="bufferOutput" messageType="ns0:SchedulForwardSoapOut"/> (MessageType of the invokeing WS)
          <variable name="count" type="xsd:integer"/>
          <variable name="n" type="xsd:integer"/>
Count and n are counter for the while loop. Count is initial 1. For n i have follow expression:
<assign name="prepareLoop">
<copy>
<from expression="ora:countNodes('bufferOutput','parameters','/ns0:SchedulForwardResponse/ns0:SchedulForwardResult/ns0:ArraySchedulType[1]')"></from>
<to variable="n"/>
</copy>
</assign>
In the BPEL Console i saw, that the value of n is1 and not 3 as i thought. When i set ora.countNodes to SchedulForwardResult n is null in the console.
Does anybody try befor to copy such a content of a variable into another variable or has a idea how i can implement these?
