Which again points out that this book belongs in the "Worst books on this 
topic" category.  Either it has the bad example verbatim, or it fails badly 
in teaching its dedicated reader how DOM scripting works.  Given that "valid 
HTML is simply a subset of XML" (probably the most ridiculous claim in this 
book, to be found on page 8), both are equally likely.
