Use XPath that will return your target attribute and convert the result to boolean :

boolean(//target_element/@target_attribute)

or similar approach but using exists() function :

exists(//target_element/@target_attribute)

_{Actually, the context isn't clearly stated in the question, for example, maybe the context element in your case is the target element already, so you don't need //target_element/ part.}

Also, you can return all of the attribute names for the target element:

//target-element/(@*[1])
