How can I get both a HTML and a PDF output from the same XML
source file?
I thoroughly read the FAQ (in particular the "How do I chain stylesheets"
item) and I tried hard to get both a (X)HTML and a PDF output from the
same XML source file by applying two different XSL-T stylesheets.
The first stylesheet is a regular XML->(X)HTML converter and it works fine.
The second stylesheet tries to create a XSL-FO file from the XML source
and post-process it with the Cocoon XSL:FO engine. This second XSL-T
stylesheet does not work. I'm able to get a valid PDF file sent to my
internet browser (MS IE 5.5 on Windows 98) but this PDF file is presented
in the browser window as it was a ASCII text file. Acrobat Reader is not
invoked by the browser.
As long as I can understand, this happens because of the lacking of the
<?xml version="1.0"?> element in the XSL:FO output produced by my XSL-T
stylesheet. Unfortunatley, I cannot insert this element in my output
using the "xsl:processing-instruction" because the XSL engine complains
about an illegal operation ('processing-instruction cannot be "xml"'). I
did not understand how to use the second technique mentioned in the "my
processing instruction disapper..." of the FAQ, that is by using an
"apply-templates" element that matches processing instructions, so I did
not try it.
Does anybody know how to get both HTML and PDF output from the same XML
file by applying two different stylesheets?
Does anybody have a working example of a single XML file converted into
both HTML and PDF using different stylesheets?
Many thanks in advance

Hi,
if you can use a parameter to specify the output format, then following
style should work (you have to refer to it in your xml file, of course).
At leats I use it in this way:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format">
<xsl:param name="out"/>
<xsl:param name="lang"/>
<xsl:template match="/">
<xsl:processing-instruction
name="cocoon-process">type="xslt"</xsl:processing-instruction>
<xsl:choose>
<xsl:when test="$out='html'">
<xsl:processing-instruction
name="xml-stylesheet">href="styles/style_html.xsl"
type="text/xsl"</xsl:processing-instruction>
</xsl:when>
<xsl:when test="$out='pdf'">
<xsl:processing-instruction
name="xml-stylesheet">href="styles/style_fo.xsl"
type="text/xsl"</xsl:processing-instruction>
</xsl:when>
<xsl:when test="$out='xml'">
<xsl:processing-instruction
name="xml-stylesheet">href="../styles/style_xml.xsl"
type="text/xsl"</xsl:processing-instruction>
</xsl:when>
</xsl:choose>
<xsl:copy-of select="*root node of your xml source file*"/>
</xsl:template>
</xsl:stylesheet>
Hope this helps.

Posted by 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>
