Z1WHCUTM and Z1CUSTCD are at same level under node  Z1WHCUSTCH.

Target:

BOX             0..n                   --     Z1WHCUSTC when Z1WHCONS is initial

MIXPLT         0..n                     --      Z1WHCONS

    BOX            0..n                    --  --     Z1WHCUSTC when Z1WHCONS is not initial

       Line            0..n                  --        Z1CUSTCD

         comment    0..n               ---    Z1WHCUTM-comment field

First Box and Mixplt are at same level.

I am not getting proper data when BOX and BOX with MIxplt data is coming in source xml.

How can I do it using graphical mapping or UDF.
