Parsing a OneNote section fails on ArrayOfPropertyValues and an unknown FileNode

[ajtorrens]

Description

I’m using pyOneNote to parse a local .one section file from OneNote for Mac. The section opens successfully in OneNote, but parsing it with the installed pyOneNote command-line tool fails before extracting content.

Running the parser directly produces:

File "pyOneNote/FileNode.py", line 641, in __init__
  raise NotImplementedError('ArrayOfPropertyValues is not implement')
NotImplementedError: ArrayOfPropertyValues is not implement

I also tried the section with onenote-exporter (https://github.com/strick-j/onenote-exporter, commit 2dc051d). That project contains a local workaround for ArrayOfPropertyValues, so it gets further. It then fails with:

File "pyOneNote/FileNode.py", line 181, in __init__
  self.children.append(FileNodeList(file, self.document, self.data.ref))
AttributeError: 'FileNode' object has no attribute 'data'

Tracing the exporter failure locally showed an unknown FileNode ID (0x1D7) with baseType == 2 in the Meetings section. A second section from the same notebook fails similarly on unknown node ID 0x13D, also with baseType == 2. Both sections fail when tested individually. The standalone pyOneNote command above was run against the Meetings section; I have not confirmed whether it produces the same ArrayOfPropertyValues error on the second section.

This appears related to [issue #4](#4), which reports the same missing-data AttributeError while following a child FileNodeList. I understand that issue is closed, but the exporter comparison still encounters this failure. The ArrayOfPropertyValues error may be a separate unsupported case.

Could you advise whether these structures are supported in a newer version, or whether this indicates a parser bug? I can investigate a fix, but I have not tried skipping unknown nodes because that could silently omit referenced content.

Reproduction

I can reproduce this locally with pyOneNote 0.0.2 and a OneNote for Mac backup section, but I cannot provide the file publicly because it contains sensitive information.

This produces the ArrayOfPropertyValues traceback above. The missing-data traceback was observed separately when running onenote-exporter with its local workaround.

Environment

• macOS Tahoe 26.7
• Python 3.12
• pyOneNote 0.0.2
• onenote-exporter commit 2dc051d for the comparison run
