= rspec_hpricot_matchers A matcher similar to RSpec's +#have_tag+ sitting atop Hpricot rather than wrapping +#assert_select+. == Usage Include RspecHpricotMatchers in your +spec_helper+: Spec::Runner.configure do |config| config.include RspecHpricotMatchers end As its first argument, match_element() accepts any CSS or XPath selectors which are supported by Hpricot. response.should match_element('form[@action*=session]') response.should match_element('ul > li + li') Expectations can be placed upon the inner text of the matched element by providing another argument, which should be either a String or a Regexp: response.should match_element('h1', 'Welcome') response.should match_element('p', /a very important blurb/i) Expectations can be placed upon the number of matched elements by passing an options hash: response.should match_element('abbr', :count => 1) # exactly one response.should match_element('dt', :minimum => 4) # at least 4 response.should match_element('dd', :maximum => 4) # at most 4 response.should match_element('a.outgoing', /rspec/i, :count => 2) The :count key also accepts a Range, making the following equivalent: response.should match_element('tr', :count => 3..5) response.should match_element('tr', :minimum => 3, :maximum => 5) A block can be passed to #match_element to search for elements within the matched element: response.should match_element('thead') do |thead| thead.should match_element('th', :count => 5) end This also allows arbitrary expectations to be applied from within the block, such as: response.should match_element('dl dd.sha1') do |dd| dd.inner_text.length.should == 40 end == Notes Currently, this implementation does not support substitution values as assert_select did (by way of HTML::Selector): # Not yet supported: response.should match_element('li[class=?]', dom_class) response.should match_element('tr.person#?', /^person-\d+$/) I personally rarely use these, and Hpricot's advanced selectors make them mostly useless, as far as I can tell, so I am unlikely to implement them myself. This match_element() further differs from the assert_select-based implementation in that the nested match_element() calls must *all* pass on a single selected element in order to be true. This was a source of confusion in RSpec ticket #316. There is a spec covering this case if you need an example.
