In queryDataNodes, a special-case algorithm is used for cases without leaf-condition/text-condition and fetching all descendants. It is called getDataNodesUsingRegexQuickFind.

Using openroadm model, this returns incorrect results for queries such as '//openroadm-device', returning only direct descendants. In this case, this regex is used:

.*\/openroadm-device(\[@(?!.*\[).*?])?(\/.*)?$

This regex will not match descendants with nested lists, like:

/openroadm-devices/openroadm-device[@device-id='C201-7-1A-1']/org-openroadm-device/degree[@degree-number='4']

but it can match this:

/openroadm-devices/openroadm-device[@device-id='C201-7-1A-1']/org-openroadm-device
