Scraping javascript-generated data using Python
javascript, python, screen-scraping, web-scraping
Solution
There's also dryscape (a library written by me, so the recommendation is a bit biased, obviously :) which uses a fast Webkit-based in-memory browser to navigate around. It understands Javascript, too, but is a lot more lightweight than Selenium.
Problem
I want to scrape some data of following url using Python. http://www.hankyung.com/stockplus/main.php?module=stock&mode=stock_analysis_infomation&itemcode=078340 It's about a summary of company information. What I want to scrape is not shown on the first page. By clicking tab named "재무제표", you can access financial statement. And clicking tab named "현금흐름표', you can access "Cash Flow". I want to scrape the "Cash Flow" data. However, Cash flow data is generated by javascript across the url. The following link is that url which is hidden, http://stock.kisline.com/compinfo/financial/main.action?vhead=N&vfoot=N&vstay=&omit=&vwidth= Cash flow data is generated by submitting some option value and cookie to this url. As you perceived, itemcode=078340 in the first link means stock code and there are as many as 1680 stocks that I want gather cash flow data. I want make it a loop structure. Is there good way to scrape cash flow data? I tried scrapy but scrapy is difficult to cope with my another scraping code already I'm using.
