Getting a reference to HTML attributes inside NVDA

[ehteshamulhaque71]

Is it possible to get a reference to HTML attributes (default and custom) inside NVDA? Let's say I have a tag <textarea id="myID" rows="5" data-current-line="2"></textarea>. Is it possible to get a list of these attributes and their values inside NVDA for this object using an add-on so that I can perform some action using the attributes?

I found that api.getFocusObject().devInfo gives IAccessible2 attributes, which lists id and class, but I could not find the remaining attributes like rows and the custom attribute data-current-line.

NVDA only has access to the accessibility tree via IAccessible2 attributes, full HTML markup is not passed through to the accessibility APIs consumed by screen readers.
