Walter and Bruce have jumped ahead a few steps from where I was
heading but basically it's an increasingly common scenario where
web pages are no longer primarily html but rather are
A headless browser is the brute force way to deal with such issues
but a better (purer?) way is to access the same API that the browser
is using. Many web sites now publish RESTful APIs with web
services that you can call directly. It is worth investigating
whether your target has this. If so that will generally provide
a much nicer solution than trying to drive a headless browser.
Finally you need to consider whether you have the right to the
data without running a browser? Many sites provide information
for free but get paid by adverts. If you bypass the web screen
(adverts) you bypass their revenue and they do not allow that.
So you need to be sure that you are legally entitled to scrape
data from the site or use an API.
Otherwise you may be on the wrong end of a law suite, or at
best be contributing to the demise of the very site you are
trying to use.
