How do I do an xpath regex search in my Cucumber / Capybara step definition (Rails 3)?

Question

I have a Scenario that validates that the image I just uploaded exists on the next page.

This below works great, except that I have a variable folder structure based on the listing_id. How can I use regex here to match image to only the filename instead of the entire url?

Then /^I should see the image "(.+)"$/ do |image|
    page.should have_xpath("//img[@src=\"/public/images/#{image}\"]")
end

Answer 1

Try page.should have_xpath("//img[contains(@src, \"#{image}\")]"), which will match any img whose src contains your filename.
