 <Inventories 
  xmlns:_cat="http://www.ibm.com/xmlns/prod/commerce/9/catalog" 
  xmlns:_inv="http://www.ibm.com/xmlns/prod/commerce/9/inventory" 
 >

  <_inv:Inventory ProductPartNumber="TAPL-01" >
          <_cat:Item ItemPartNumber="TAPL-0101" >
                <Quantity>101</Quantity>
          </_cat:Item>
          <_cat:Item ItemPartNumber="TAPL-0102">
                <Quantity>102</Quantity>
          </_cat:Item>
  </_inv:Inventory>
 </Inventories>

 

It will build a map and the key is the name and the value is either a string or a list if there are multiple values for the same name.
