Use this function to create a syntax element as the first child of the specified syntax element.
Do not use cniCreateElementAsFirstChild when creating a message body folder (such as XML, XMLNS, MRM, BLOB), because it does not associate an owning parser with the folder. To create a message body folder, you can use one of the following functions:
When the message body folder has been created, you can call cniCreateElementAsFirstChild to create elements under the folder. You can use cniCreateElementAsFirstChild because the parser, which is associated with the message body folder, is inherited.
CciElement* cniCreateElementAsFirstChild(
int* returnCode,
CciElement* targetElement);
If successful, the address of the new element object is returned. Otherwise, a value of zero (CCI_NULL_ADDR) is returned, and the returnCode parameter indicates the reason for the error.
