Hi everyone,

In the xml below, can I use xpath to find the <message> node which do
not have any child <message> node. The conversion I am working, I have
to start from the child node and move up to the top node. There could
be multiple child nodes. Many thanks in advance.

The xpath should give me the following node:
<message subject="attach 1.1">
<message subject="attach 1.2">
<message subject="attach 2.1">
<message subject="attach 2.2">
