codebytes: XSLT Example [XML][(X)HTML][XSLT][Note]

XSL stands for EXtensible Stylesheet Language, and is a style sheet language for XML documents.

XSLT stands for XSL Transformations. We'll be using XSLT to transform a sample XML document into XHTML.

If you want to take a quick tutorial about XSLT visit here.

Our sample XML file is:

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="sheet.xsl"?>

<People>
  <Person>
    <ID>1</ID>
    <Name niceName = "false">A Guy</Name>
    <Address>Streets</Address>
    <Company>None</Company>
    <EMail>some@person.com</EMail>
    <Info show  = "yes">Likes Candies</Info>
  </Person>
  
  <Person>
    <ID>2</ID>
    <Name niceName = "true">Another Guy</Name>
    <Address>Streets</Address>
    <Company>Some Company</Company>
    <EMail>some@otherPerson.com</EMail>
    <Info show = "no">Likes Ladies</Info>
  </Person>
</People>

And we'll be using this stylesheet with the name 
"sheet.xls"

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/People">

        </xsl:for-each>
        
        <h3 style="color:green;">[Choose] Display only if Info[@show='yes']</h3>

         </xsl:choose>

        </xsl:for-each>
        
        <h3 style="color:green;">[sort] Display according to Decreasing ID numbers.</h3>
        <xsl:for-each select="Person">
