Mearging tow xml in single list

[mirajgodha]

Hi, I have tow XML like this:
XML 1:
<DisplayValues>  
   <DisplayValuesRow QUERY_CNTRL_NM="trxnTransactionDateFromDPk" filterDisplayValue="Transaction Date"/>
</DisplayValues>
XML2:
<QueryParams>
  <QueryParamsRow QUERY_CNTRL_NM="trxnTransactionDateFromDPk" QUERY_CNTRL_VAL="12"/>
<QueryParams/>

Resultant List Required:
---------------------------------------
filterDisplayValue   ---  QUERY_CNTRL_VAL
---------------------------------------
Transaction Date     ---     12
----------------------------------------

   
Now i have to make a list using these tow xml's. I want to have tow columns in list: One is pointing to /DisplayValues/DisplayValuesRow@filterDisplayValue
Second column pointing to: /QueryParams/QueryParamsRow@QUERY_CNTRL_VAL

Now the problem is how to give condition in dataSource of list(or list columns) on the basis of 'QUERY_CNTRL_NM', i.e. the filterDisplayValue and QUERY_CNTRL_VAL columns of list should mapped on the basis of 'QUERY_CNTRL_NM'attribute of both XML's.
