This step clicks a series of elements by executing a series of XPath lookups. If there were 3 elements to click, their XPaths would\u00a0 be:<\/p>\n

There should be at least one element found, so it returns an error if none are found. It uses findElements() instead of findElement() because findElements() does not throw an exception if nothing is found. This makes it easy to catch all other exceptions and report them errors. If it finds more than one element with a single query, then something is wrong with the XPath, so it also reports this as an error.<\/p>\n
