Hello, I'm faced with an HTML page that contains a FORM tag with a unique identifier, and an INPUT (button) tag without any unique identifiers associated with it. In the same page, there are other FORMs, with the same exact INPUT (button) tag. My question is, knowing the identifier of the FORM, how do I select the INPUT button on that specific form? I tried this as the selector: <tagname="form" AND name="addcomment" AND tagname="input" AND value="SUBMIT"> (where the outer FORM element has name attribute "addcomment", and the inner INPUT element has value attribute = "SUBMIT").
