I have coded a structured pattern that should be detecting <input/> elements with an id attribute but no name attribute.  All the details are in the image below.  There is a regex match on the attribute names that should not match if the 'name' attribute already exists.  However, it does not fail, but instead matches an element like <input id="foo" name="foo" style=""/>.  Also, it does not seem to matter if I toggle the regex between "should" and "should NOT".  It matches either way.

Thanks,

Josh
