generating request

I have a structure with attributes and their values for every risk.
I want to use it depending on value for risk in .xls file.
It's not only value but very large structure.
for example:
in xls true true true
req:

<InstanceData>
            <RiskList>
              <Risk id="one">
                  </Risk>
               <Risk id="two">
                 </Risk>
               <Risk id="three">
               </Risk>
            </RiskList>
           </InstanceData>

in xls true false false

<InstanceData>
            <RiskList>
              <Risk id="one">
                  </Risk>
             
            </RiskList>
           </InstanceData>

in xls true false true

<InstanceData>
            <RiskList>
              <Risk id="one">
                  </Risk>
               <Risk id="three">
               </Risk>
            </RiskList>
           </InstanceData>

If it is only value, it's not a problem with get data.
What if it is structure with thousands of lines nested tags in tags in tags in tags...
