RE: How can I get both a HTML and a PDF output from the same XML source file?

[John Menke <jo...@eagleinfosystems.com>]

I use the following code at the top of my XML files.  It checks the query
string for a value and picks the correct Stylesheet.

<?xml version="1.0"?>
<!-- edited with XML Spy v3.5 (http://www.xmlspy.com) by john menke (eagle
information systems) -->
<?cocoon-process type="xsp"?>
<?cocoon-process type="xslt"?>
<xsp:page language="java" xmlns:xsp="http://www.apache.org/1999/XSP/Core">
	<page title="My Page">
		<xsp:logic>

	String[] param = request.getParameterValues("dummy");
	String stylesheet;
	if (param != null) {
		stylesheet = "pdf.xsl";
	} else {
		stylesheet = "html.xsl";
	}


</xsp:logic>
		<xsp:pi target="xml-stylesheet">
                href="<xsp:expr>stylesheet</xsp:expr>"
                type="text/xsl"
</xsp:pi>
