It's possible to do an XHR call and render the output with Selenium?
Selenium is really designed to be an external control system for a web browser.  I don't think of it as being the source of test data, itself.  There are other unit-testing frameworks which are designed for this purpose, but I see Selenium's intended purpose to be different.
Well, the title says it all... It is possible to perform an XmlHttpRequest from Selenium/Webdriver and then render the output of that requests in a browser instance ? If so, can you enlight me please ?
