Cucumber step to match table rows with Capybara (within wrapper method suppor...

Here is an update from the original card to support Capybara's within method.
The original card always looked thru all tables on the page.

The 2 points i changed were :

to use Capybara's all method instead of using Nokogiri directly
and to use Capybara's node.text method instead of Nokogiri's node.content method

And finally here is the code :

Then /^I should( not)? see the following table rows?( in any order)?:?$/ do |negate, unordered, expected_table|
  expectation = negate ? :should_not : :should
  rows = all(:xpath, './/tr').collect { |row| row.all(:xpath, './/th|td') }
  expected_table = if expected_table.is_a?(String)
    # multiline string. split it assuming a format like cucumber tables have.
    expected_table.split(/\n/).collect do |line|
      line.sub!(/^\|/, '')
      line.sub!(/\|$/, '')
      line.split(/\s*\|\s*/)
    end
  else
    # vanilla cucumber table.
    expected_table.raw
  end
  expected_table.all? do |expected_row|
    first_row = rows.find_index do |row|
      expected_row.all? do |expected_column|
        first_column = row.find_index do |column|
          content = column.text.gsub(/[\r\n\t]+/, ' ').gsub(/[ ]+/, ' ').strip
          content.include? expected_column.gsub('  ', ' ').strip
        end
        if first_column.nil?
          false
        else
          row = row[(first_column + 1)..-1]
          true
        end
      end
    end
    if first_row.nil?
      false
    else
      if unordered
        rows.delete_at(first_row)
      else
        rows = rows[(first_row + 1)..-1]
      end
      true
    end
  end.send(expectation, be_true)
end
