DELETE statement

The DELETE statement detaches and destroys a portion of a message tree, allowing its memory to be reused. This statement is particularly useful when handling very large messages.

Syntax

If the target field does not exist, the statement does nothing and normal processing continues. If any reference variables point into the deleted portion, they are disconnected from the tree so that no action involving them has any effect, and the LASTMOVE function returns FALSE. Disconnected reference variables can be reconnected by using a MOVE... TO... statement.

Example

DELETE FIELD OutputRoot.XMLNS.Data.Folder1.Folder12;
DELETE LASTCHILD OF Cursor;
