I want to crawl and collect information about products and their prices from some e-commerce websites like Walmart or Target, and I found using Schema Markup Validator or Google's Rich Result Test to extract structured data like price, description, etc would be easier than searching for attributes in HTML with xpath etc. However I don't know how to download the extracted data so that I can integrate it in my Java code. Or better, is there any way I can program this in Java with the help of these schema testing tools?
