Is it possible for nokogiri to parse content loaded via ajax? If not how would I accomplish this?
回答1:
Nokogiri can't see the AJAX content because it isn't a Javascript parser, and, as a result, can't interpret it and do the needed request.
What you want is something like Watir, or one of its spinoffs, depending on your OS. They will launch a browser, which can process the Javascript and resulting AJAX request.
Then, you can request the page's contents, and do your parsing of the DOM using Nokogiri.
The process is too specific for a generic example, but the Watir platform page will point you to the browsers supported. The examples are pretty easy is to figure out, so you should be able to piece something together nicely.
回答2:
Just post your content to the server with an AJAX call. Here a normal controller action can handle the response, including parsing with Nokogiri.
If you mean, 'Can I parse the result of an AJAX call with Nokogiri?', the answer is no. Nokogiri is server-side software and the results of an AJAX call arrive at the client.
