Use ISNULL function. or compare the value of that XML tag with NULL.

Or you can use FieldName function.
For example:
| Quote: |
FIELDNAME(InputRoot.XML) returns 'XML'.
FIELDNAME(InputBody) returns the name of the last child of InputRoot, which could be 'XML'.
FIELDNAME(InputRoot.*[<]) returns the name of the last child of InputRoot, which could be 'XML'.
|
To store the fieldname in a variable:
| Code: |
DECLARE thePath character;
SET thePath = FIELDNAME(InputRoot.XML.*[1]);
[\code]
You can use this to findout which is the next tag... |
