Discussion

This method constructs a URL given the string value of an element attribute. Examples include the href attribute of a DOMHTMLAnchorElement object, or the src attribute of a DOMHTMLImageElement object. This method only applies to attributes that refer to URLs.

This method is similar to init(string:) in the NSURL class, except that URLWithAttributeString: handles relative URLs automatically based on the current document’s location.
