Extracting line numbers from org nodes?

[lenianiva]

Is it possible to extract the line number from a node? I need this functionality because I want to signal to the user the document is invalid.

Yep, nodes have a .linenumber property, e.g. see usage example here https://github.com/karlicoss/promnesia/blob/78e7d73b40c88c4c0374cd9a495d2347017f4b55/src/promnesia/sources/org.py#L167
