You are just quoting an API, in this case the DOM, and unless you use a language
that equates NodeLists to arrays, you'll need to replace [0] with .item(0). In
fact, using the first item in the childNodes here is probably going to bite you
very hard since for newbie and question, the first node will be a text node
containing whitespace.
Using other APIs you could get what you want. Both Perl and Python have APIs
that will access the above as root.newbie.question.whatsUp, or something locally
similar.
You could also use XPath: /newbie/question/whatsUp.
