How to access element using Watir and XPath

Question

I have some HTML that looks like this:

<h1 id="header">Header</h1>

I would like to click it using Watir and XPath.

Answer 1

After watir-webdriver 0.5.1 selecting random element with an xpath was updated to:

browser.element(:xpath => "//h1[@id='header']").click
