Do not call getMetadata twice. It is heavy

parentElement can be null, can we add a null check?

If previousNode or previousNode.parentElement is null, this will still be a problem.
BTW, what is the parent element here?

It should to be the UL or OL element, but I noticed that the list structure can different to just <ol><li></li><ol>, then I changed the code to use findClosestElementAntecesor to find the ul or ol element that contain the metadata.
