In-Depth Information
When testing a document's nodes, be careful of the whitespace bug! If you break lines,
for example, between the
<head>
and
<title>
tags, the whitespace is considered a text
node and your output might not be consistent. There are a number of Web sites that deal
with the whitespace bug and offer programmatical ways to solve the problem when tra-
versing the DOM tree. See
https://developer.mozilla.org/en/Whitespace_in_the_DOM
(see
Figure 15.5)
