2.  Code of data.xml
---------------------------------------------------

<?xml version="1.0" encoding="ISO-8859-1"?>
<!-- Edited by XMLSpy® -->
<?xml-stylesheet type="text/xsl" href="data_xslt_test.xsl"?>
<catalog>

IE Conditional Comments

Following is from the http://haslayout.net/condcom, more detail can reference it

Overview

IE Conditional Comments (or condcom for short) are special comments that enable authors to use the instructions that only Internet Explorer 5.0 and above on Windows platform will see.

Various types of conditional comments

Regular comment:

<!--This is a comment-->

IE conditional comment:

<!--[if IE]> <![endif]-->

Reversed anti-IE comment:

<!--[if !IE]>--> non-IE HTML Code <!--<![endif]-->

Reversed IE conditional comment (rarely needed):

<!--[if ! lt IE 7]>
    <![IGNORE[--> <![IGNORE[]]>
        Code for browsers that match the if condition
<!--<![endif]-->

In a nutshell, any browser except Internet Explorer on a Windows platform will treat conditional comment as a regular HTML comment. You cannot use condcoms in the CSS code itself. IE conditional comments are useful for hiding or revealing the code to IE, which in turn allows authors to use CSS "hacks" in a more appropriate fashion.

IE9 compatible mode

Problem:

 When you written in web page, if you have some CSS3 code, but the 
 IE9 browser open page using the quirk mode, and you will miss the your style,
 how do you setting the IE9 browser to standard mode??

Solution:

(a)  Before html, you can type the doctype
     <!DOCTYPE html>

(b)  in <head> </head> tag, adding the

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9">

Eclipse package meaning

Problem: what do different packages of eclipse like

Indigo
Helios SR1
Helios
Galileo
Ganymede
Europa


Solution: These are code names for major releases of the Eclipse IDE/platform. For example, I think Galileo was Eclipse 3.5. They started relying heavily on the code names about 4-5 years ago, not sure why - it can be confusing post-release.

Helios is the latest stable release. "SR1" means there's been a service release applied (bug fixes).
