Biztalk Looping functoid Problem at nested level during Mapping.

I am trying to write a mapper. whose input xml is in the format:

<OR_Items>
<Item>
  <Name>item1</Name>
  <Value>item1Value</Value>
</Item>
<Item>
  <Name>item2</Name>
  <Value>item2Value</Value>
</Item>
<LineItems LineItemName="123">
 <SubItems>
  <SubItem>
    <Name>subitem1</Name>
   <Value>subitem1Value</Value>
  </SubItem>
  <SubItem>
   <Name>subitem2</Name>
   <Value>subitem2Value</Value>
 </SubItem>
 </SubItems>
 <SubItems>
  <SubItem>
    <Name>1</Name>
   <Value>value</Value>
  </SubItem>
  <SubItem>
   <Name>name</Name>
   <Value>value</Value>
 </SubItem>
 </SubItems>
  </LineItems>
<LineItems LineItemName="abnbdf">
 …..
…..
</LineItems>
<OR_Items>

where Name contacins the name of anyitem and value contanes value.I want to
convert this into a simple xml like:

<OutputXml>
<item1>item1Value</item1>
<subitem1>subitem1Value</subitem1>
<subitem2>subitem2Value</subitem2>
</OutputXml>
