Instance Method Details

#detect_element(element_name, options = {}) ⇒ Object

this is a handy method for getting info out of the doc since so many of the elements can be multiple, and you may need to pick just one, this method lets you do that by specifying the element, then how to select it by matching values to an attr. It can return just the first one of the element by default. It also can get the value from the element rather than return the element
