The books node at the top of the tree has two book child tags. In each book, there are several nodes author, publisher, and title. Author, publisher, and title nodes have text child nodes that contain text, respectively.
The code that reads the book XML file and displays the content in the DOM is shown in Listing 2.
Listing 2. Reading book XML with DOM
The script first creates a new DOMDocument object and loads the book XML into the object using the Load method. The sc

Brief IntroductionInternet Explorer 7 contains a number of improvements on cascading style sheet (CSS) parsing and rendering. These improvements are meant to improve Internet Explorer's ability to interpret cascading style sheets to meet recommended standards for the consortium, while providing developers with a collection of features to rely on.
In some cases, these changes may have an impact when existing content is rendered in a way that is incompatible with IE6. This behavior is

Importing (import) and hiding CSS
Since older browsers do not support CSS, a common practice is to use the @import technique to hide the CSS. For example:
@import URL (main.css);
However, this method does not work for IE4, which makes me very headache for a while. Later I used the following wording:
@import main.css;
This can also be hidden in the IE4 CSS, hehe, also saved 5 bytes. To learn more
for IE bugs, there are too many CSS tips (hacks), and I use only two of these methods, and whether or not Microsoft is better at supporting CSS in the upcoming IE7 Beta, both of these are the safest.
1. Method of annotation
(a) to hide a CSS definition in IE, you can use the selector (child-selector):
The following is a reference fragment:Html>body p {/* Definition Content * *}
(b) The following wording is only understandable by IE browser (hidden fr

Why is our CSS so messed up-we're really easy to get caught up in this confusion.
Sometimes this is the result of sloppy programming at first, sometimes because of late multiple additional code (hacks) and modifications.
Either way, it's not inevitable. Write clean, super manageable CSS is simple, as long as you go the
