Using an imaging crawler to extract text and images from a webpage to avoid parsing the DOM. Reason include dynamic content loading, diverse HTML usage and consistent training data sets for ML models. I have edge detection running in OpenCV, but it's a bit problematic and brittle. My reasoning is that a ML model would be a bit more robust and useful to others.
