I wonder how to test the existence of a field before matching its value.
for example,
$Root/XMLNSC/COMPLAINT/VERSION testing existence.
$Root/XMLNSC/COMPLAINT/VERSION = 2
any insight would be appreciated.

If you mean that you want to take one route if a tag has a specific value, and another route if it simply exists, then code 2 tests.
If you want to test that it exists and has a specific value, then the test for the specific value will obviously fail if the tag does not exist.
Or are you asking a different question?

I hope, his question is the one you've mentioned then following should be suitable.
It totally depends what he is looking for while checking the field for some value or if that exists at all and then do some logical comparison. Following will work in any case, I believe :
| Code: |
IF FIELDTYPE(InputRoot.XMLNS.Message1.Name)
IS NULL THEN
// Name field does not exist, take error
action....
... more ESQL ...
ELSE
// Name field does exist, continue....
... more ESQL ...
END IF

Yes, this is exactly what I mean. Sorry for not being clear enough.

I was more worried I was answering a different question and providing an answer that was, at best, irrelevant.
