Working with the response DOM
by Andy Watts

Rate this Message:
Hi,
Anyone know a way to traverse/query the DOM in a response? I'm trying to write reusable story step implementations and as much as possible want to work with the actual response from a previous GET. As an example, I often have buttons that POST/PUT a hidden value. My goal is a reusable step implementation that takes the button label and works the existing response DOM to make an appropriate POST/PUT. - Andy |

I completely forgot about Hpricot
http://code.whytheluckystiff.net/hpricot/ Looks perfect for this. - Andy

I've been wondering the same for quite a while
http://www.nabble.com/simple-story,-extract-link-t4518721.html but hadnt asked the question so succinctly In that thread, Pat suggests helpers like click_link and submit_form If you progress along these lines, please post your solution, I'm very interested. linoj On Oct 24, 2007, at 12:43 AM, Andy Watts wrote: > > I completely forgot about Hpricot > http://code.whytheluckystiff.net/hpricot/ > > Looks perfect for this. > > - Andy > > > > Andy Watts wrote: >> >> Hi, >> >> Anyone know a way to traverse/query the DOM in a response? >> >> I'm trying to write reusable story step implementations and as >> much as >> possible want to work with the actual response from a previous GET. >> >> As an example, I often have buttons that POST/PUT a hidden value. >> My goal is a reusable step implementation that takes the button >> label and >> works the existing response DOM to make an appropriate POST/PUT. >> >> - Andy >> >> > > -- > View this message in context: http://www.nabble.com/Working-with- > the-response-DOM-tf4681975.html#a13378962 > Sent from the rspec-users mailing list archive at Nabble.com. > > _______________________________________________ > rspec-users mailing list > rspec-users@... > http://rubyforge.org/mailman/listinfo/rspec-users _______________________________________________ rspec-users mailing list rspec-users@... http://rubyforge.org/mailman/listinfo/rspec-users |

Re: Working with the response DOM - Step implementations using Hpricot

I'm playing with step implementations that use hpricot to manipulate response.body.
Here's what I have so far. Very much work-in-progress, but may be of some use to you. #This step implementation takes a button's label, collects the inputs and does the POST/PUT add.when("I click the $button_text button") do |button_text| h = Hpricot(response.body) form = h.search("form[button][text()=#{button_text}]").first action = form[:action] method = form[:method] headers = {'HTTP_REFERER' => request.env['REQUEST_URI']} params = {} form.search('input').each{|i| params[i[:name]] = i[:value] } send(method, action, params, headers) end #This step implementation takes an input field & value, and updates the response.body add.when("I set the $input_field to $value") do |input_field,value| input_field.each{|s| s = s.sub!(/^'(.*?)'$/,'\1') } # strip the quotes if used in the input field input_field.gsub!(' ', '_') # join to get an id to search for..not robust enough? h = Hpricot(response.body) # get body in Hpricot field_element = h.search("input##{input_field}").first # find the input field field_element[:value] = value # update the field's value response.body = h.to_html # put the modified body back in the response end - Andy
