Scraper - a Google Chrome Extension
Your first, and probably easiest option is to go with a Google Chrome plugin that's already created for you. It's called scraper and the extension is for getting data out of web pages and into spreadsheets. Simple enough. Head to the page, download it, and reboot your Chrome browser. To use it: highlight a part of the webpage you'd like to scrape, right-click and choose "Scrape similar...". Anything that's similar to what you highlighted will be rendered in a table ready for export, compatible with Google Doc.
