How should I get JSON format path from expr inside leafref?

[lyzliyuzhi91]

I get a leafref node, and I want to create an isntance for the leafref's target.
But once I call lyd_new_path by the path getted from lyxp_get_expr, it failed. It seems that because the path's prefix is not a module name but a module prefix.

You are right and there is no direct way of transforming the prefix into the module name so you will have to do so manually somehow.
