Based on following table (I have kept spaces between the rows for clarity)

Path
-----------
\node1\node2\node3
\node1\node2\node3\node5

\node1\node6\node3

\node1\node4\node3
\node1\node4\node3\node7
\node1\node4\node3\node8
\node1\node4\node3\node9
\node1\node4\node3\node9\node10

I want to get all the paths containing leaf node. So for instance, following will be considered leaf nodes for path \node1\node4\node3

\node1\node4\node3\node7
\node1\node4\node3\node8
\node1\node4\node3\node9\node10

The following will be the output:

Output
---------------------------
\node1\node2\node3\node5
\node1\node6\node3
\node1\node4\node3\node7
\node1\node4\node3\node8
\node1\node4\node3\node9\node10

Pls. suggest. Thanks.
