NotebookImport ignoring multiple style cells

Question

Bug introduced in 11 or earlier and persisting through 12.1

[...] I have filed a report to the development team, raising the issue to them. [...]

[CASE:3802659]

---

CellPrint[Cell["test", "Text"]]
CellPrint[Cell["test2", "Text", "MyStyle"]]
CellPrint[Cell["test3", "Text", "Text"]]

NotebookImport[EvaluationNotebook[], "Text"]

{"test"}

Since multiple style cells are officially supported I would consider it a bug. Or have I missed something?

Answer 1

I suppose you want that to return all three cells? This does work for that:

NotebookImport[EvaluationNotebook[], "Text" | {"Text", _}]

{"test", "test2", "test3"}

One can also pull only specific combinations:

NotebookImport[EvaluationNotebook[], {"Text", "Text"}]

{"test3"}

Notably this matches none of the examples:

NotebookImport[EvaluationNotebook[], {"Text"}]
