I am using Selenium\'s python library to scrape data from a html page in Firefox.
I have had to update from Selenium 2.0 to 2.21 because the server has updated Firef
The problem about WebDriver is that it still evolves. A lot. I personally don't know about a version that supported searching by many classes in one command, so it must have been a fairly old one :).
Searching by a CSS selector should work, however:
find_element_by_css_selector(".grid-cell-inner.grid-col-name");
I don't recommend using XPath for this particular thing, because these two following expressions are a different thing:
//*[class='grid-cell-inner grid-col-name']
//*[class='grid-col-name grid-cell-inner']
