XSLT get node at same level of for-each

Question

I'm trying to get data from a node that is on the same level as the node I'm using for a for-each. How do I get the DTM nodes to return data while I am in the SVC for-each?

I thought add "/" would send me up a level but it's not working. I also thought "//" might work but that doesn't work either.

Here is my XML:

<Loop2110>
              <SVC>
                <C003_1>
                  <F235>HC</F235>
                  <F234_1>99214</F234_1>
                </C003_1>
                <F782_1>100</F782_1>
                <F782_2>75</F782_2>
                <F380_1>1</F380_1>
              </SVC>
              <DTM>
                <F374>472</F374>
                <F373>2021-03-01</F373>
              </DTM>
              <CAS>
                <F1033>PR</F1033>
                <F1034_1>3</F1034_1>
                <F782_1>45</F782_1>
              </CAS>
              <CAS>
                <F1033>CO</F1033>
                <F1034_1>45</F1034_1>
                <F782_1>99.54</F782_1>
              </CAS>
              <REF>
                <F128>6R</F128>
                <F127>1</F127>
              </REF>
              <AMT>
                <F522>B6</F522>
                <F782>100.46</F782>
              </AMT>
</Loop2110>

Answer 1

if you are in the context of SVC , then the expression ../DTM will select the sibling DTM node (or nodes, if there are more than one).

Alternatively, you could use following-sibling::DTM - but this assumes the nodes are in the order shown in your example.
