Capybara: How to check that an element has content among many similar elements?
===

I need to check that some content exists on the page within a specific type of selector. For example, let's say I have the following HTML:

    <h2>Headline One</h2>
    <h2>Headline Two</h2>

I know how to select only the first one on the page:

    find('h2').should have_content('Headline Two')

How would I check that the content exists among all of the `h2`s on the page?
