Examples are prefixed with boiler plate in the normal case.
In the rare case a root node is required this boiler plate shall not be
used.
Example with root node:
/ {
chosen {
...;
}
}
Teach the script to recognize that the example starts with a root node
and avoid the boiler plate in such cases.
The root node is recognized using a simple regular expression search.
