Example

Given the following XML instance document, links.xml :

 <links>       <link name="NewRiders.com" URL="http://www.newriders.com" />       <link name="Xmlandasp.net" URL="http://www.xmlandasp.net" />       <link name="MSDN Online Library" URL="http://msdn.microsoft.com/library" />  </links>

The following stylesheet displays all the elements in a table with every other row colored medium gray:

 <?xml version="1.0" encoding="UTF-8" ?>  <xsl:stylesheet version="1.1"  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">       <xsl:template match="/">            <table>                 <xsl:for-each select="links/link">                      <tr>                           <td>                                <xsl:if test="position() mod 2 = 0">                                <xsl:attribute name="bgcolor">silver</xsl:attribute>                                </xsl:if>                                <xsl:value-of select="@name" />                           </td>                      </tr>                 </xsl:for-each>            </table>       </xsl:template>  </xsl:stylesheet>

This results in the following markup:

 <?xml version="1.0" encoding="UTF-16"?>  <table>     <tr>       <td>NewRiders.com</td>     </tr>     <tr>       <td bgcolor="silver">Xmlandasp.net</td>     </tr>     <tr>       <td>MSDN Online Library</td>     </tr>  </table>
