Transform XML with XSLT Stylesheets
As the list of links won't change terribly often, you could easily store them in a simple XML document. For example:

<?xml version="1.0"?> <menu> <nextid>4</nextid> <link id="link1" title="Link 1" url="http://myserver/someplace/file1.asp" /> <link id="link2" title="Link 2" url="http://myserver/someplace/file2.asp" /> <link id="link3" title="Link 3" url="http://myserver/someplace/file3.asp" /> <!-- etc --> </menu>

You can write an XSLT stylesheet to transform that data into HTML, for example:

<?xml version='1.0'?> <xsl:stylesheet xmlns:xsl= "http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method="html"/> <xsl:template match="/"> <xsl:apply-templates select="menu"/> </xsl:template> <xsl:template match="menu"> <table align="left" width="150"> <xsl:apply-templates select="link"/> </table> </xsl:template> <xsl:template match="link"> <tr><td> <a href="{@url}"> <xsl:value-of select="@title"/> </a> </td></tr> </xsl:template> </xsl:stylesheet>

Then you can perform the transform on the server:

<%@ Language=VBScript %> <% dim xml dim xsl set xml = Server.CreateObject("MSXML2.DOMDocument.4.0") set xsl = Server.CreateObject("MSXML2.DOMDocument.4.0") xml.load Server.MapPath(".") & "\menu.xml" xsl.load Server.MapPath(".") & "\menu.xsl" %> <html> <head> </head> <body> <%Response.Write xml.transformNode(xsl)%> </body> </html>

Author's Note: For the code in this article, I've used the MSXML version 4 processor, but the code works fine with version 3. To use it with version 3, change every occurrence of Server.CreateObject("someobjectProgID.4.0") to Server.CreateObject("someobjectProgID.3.0").
