Correct Style Sheet Declaration
The root element that declares the document to be an XSL style sheet is <xsl:stylesheet> or <xsl:transform>.
Note: <xsl:stylesheet> and <xsl:transform> are completely synonymous and either can be used!
The correct way to declare an XSL style sheet according to the W3C XSLT Recommendation is:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
or:
<xsl:transform version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
Note: The xmlns:xsl="http://www.w3.org/1999/XSL/Transform" identifies the official W3C XSL recommendation namespace. If you use this namespace, you must also include the attribute version="1.0".
Note: If you are using IE 6.0 or Netscape 6 you should use one of the codes above.

Incorrect Style Sheet Declaration
This was the correct way to declare an XSL style sheet according to the W3C XSL Working Draft:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/TR/WD-xsl">
Note: The declaration above is OUTDATED, but if you are using IE 5 you should use the (incorrect) code above.

Start with your XML Document
We want to transform the following XML document ("cdcatalog.xml") into XHTML:
<?xml version="1.0" encoding="ISO-8859-1"?>
<catalog>
<cd>
<title>Empire Burlesque</title>
<artist>Bob Dylan</artist>
<country>USA</country>
<company>Columbia</company>
<price>10.90</price>
<year>1985</year>
</cd>
.
.
.
</catalog>
To view an XML / XSL document in IE 5.0 (and higher) and Netscape 7 you can click on a link, type the URL in the address bar, or double-click on the name of an XML file in a files folder.
To view an XML / XSL document in Netscape 6 you'll have to open the XML file and then right-click in XML file and select "View Page Source".
View XML file
--------------------------------------------------------------------------------
Create an XSL Style Sheet
Then you create an XSL Style Sheet ("cdcatalog.xsl") with a transformation template:
<?xml version="1.0" encoding="ISO-8859-1"?><xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl:template match="/">
<html>
<body>
<h2>My CD Collection</h2>
<table border="1">
<tr bgcolor="#9acd32">
<th align="left">Title</th>
<th align="left">Artist</th>
</tr>
<xsl:for-each select="catalog/cd">
<tr>
<td><xsl:value-of select="title"/></td>
<td><xsl:value-of select="artist"/></td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template></xsl:stylesheet>
View XSL file
--------------------------------------------------------------------------------
Link the XSL Style Sheet to the XML Document
Finally, add an XSL Style Sheet reference to your XML document ("cdcatalog.xml"):
<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href="cdcatalog.xsl"?>
<catalog>
<cd>
<title>Empire Burlesque</title>
<artist>Bob Dylan</artist>
<country>USA</country>
<company>Columbia</company>
<price>10.90</price>
<year>1985</year>
</cd>
.
.
.
</catalog>
If you have an XSLT compliant browser it will nicely transform your XML into XHTML!
