Is it possible to read OFX data iteratively, rather than all at once?

[daviewales]

ElementTree provides two ways to read XML data iteratively:

• XMLPullParser
• iterparse

Is it possible to connect these with ofxtools somehow to iteratively parse OFX data, rather than parsing it all at once?
Or some other way to parse the data one record at a time?

The reason I'm asking is that I'm hoping to add an OFX loader to Visidata, and they require loaders to yield rows one at a time to avoid blocking the UI thread.

(I'm aware that it's likely very difficult to map the entire OFX specification to tables. However, there are some parts which work nicely, such as transaction lists.)
