The goal of this project is a Chrome Extension that when clicked would allow you to select data on the websites page, and the extension would then find similar data. For example, clicking an item image on a store front would then select all of the images on that page. The same concept applies to item names, prices, etc. Selecting one would retrieve all similar occurrences on the page.
Ultimately, a Chrome extension similar to what Kimono Labs was, or what import.io still is. This would most likely be accomplished using a mix of XPath, CSS Path, regex, and possibly node.js or other packages, but exact methods are, in part, the authors choice.
Please detail relevant experience, along with a timeline estimation for completion, and feel free to ask any questions for more clarity.
