If you give every tab element id="tabs" your code will fail, firstly because there can be only be one instance of any one id in a web page, secondly because the code will count every element contained within the first (or last, not quite sure at the moment) element with id="tabs". Since you haven't linked to a code example I can't really give you any further assistance. @Codeventure
Your code will return all elements contained within the element with id=”tabs”. If you give every tab element id=”tabs” your code will fail, firstly because there can be only be one instance of any one id in a web page, secondly because the code will count every element contained within the first (or last, not quite sure at the moment) element with id=”tabs”.

Since you haven’t linked to a code example I can’t really give you any further assistance.

Firefox correctly interprets whitespace, line breaks and newlines as text elements, which sort of makes sense if you think about it. The first example on this page http://www.oracle.com/technology/pub/articles/wang-whitespace.html illustrates it quite well. About the <!, I'm not quite sure if I understand what you mean. Is it a normal html comment tag, or something that Firefox adds to the mix? @rav Nodetype 3 actually relates to all kinds of text, that is DOM elements that are not enclosed with tags.
