/**
@page get_data Getting Data
Retrieving data from Sysrepo is simple and flexible. The selection is specified using
[XPath 1.0](https://www.w3.org/TR/1999/REC-xpath-19991116/) language. Accepted expressions are limited only by
_libyang_ implementation, which means almost everything is supported.
When reading data, it is important to select the right [datastore](@ref datastores) in the session used. Be aware that
every call of these functions can simply return a copy of cached data at best (caching mentioned in [connections](@ref conn_sess))
or it can request some subtrees from one or more applications that will need to [provide them](@ref oper_subs) for
the _operational_ datastore.
Lastly, be aware that all data are modified by the [prepared changes](@ref edit_data) in the session, if any.
