As you can see, the Hello World is added on the HTML page using javascript, when I use the HTML parser, like the BeautifulSoup to parse it, it can't parse the Hello World, it is possible to me parse the actually result on how the client side really see....? Thanks.
推荐答案
在Python编写web刮刀，当我遇到了类似的问题，我发现的与BeautifulSoup非常有用的组合硒网络驱动程序。在code最终看起来是这样的：
I ran into a similar problem when writing web scrapers in python, and I found Selenium Web Driver in combination with BeautifulSoup very useful. The code ends up looking something like this:
browser = WebDriver.Firefox()
browser.get("http://www.yoursite.com")
soup = BeautifulSoup(browser.page_source)
...
使用webdriver的硒，有功能上也为等到一定的DOM元素已加载，这使得与JavaScript元素的时机更容易了。
With Selenium WebDriver, there's also functionally for a "wait until a certain DOM element has loaded", which makes the timing with javascript elements easier too.
