# Test YANG ANYDATA:
|
|
# Also Test CLICON_YANG_UNKNOWN_ANYDATA: Treat unknown XML/JSON nodes as anydata.
|
|
# Test matrix is three dimensions:
|
|
# 1. YANG spec: Add elements denotend with "u" which are either a) defined as anydata or b) unknown
|
|
# 2. Make access to elements as: a) top-level, b) in container, c) in list
|
|
# 3. data is in a) startup b) netconf 3) state
|
|
|
|
# Load an XML file with unknown yang constructs that is labelled as anydata
|
|
# Ensure clixon is robust to handle that
|
|
# Test is that unknown XML subcomponents (with label u) are loaded in an xml file.
|
|
|
|
# Magic line must be first in script (see README.md)
