Alternate CSS stylesheets.

I currently use the following XSL fragment to include a css
stylesheet
in the resulting html documents:

------------------------------------------------------------
---------
<?xml version='1.0'?>
<xsl:stylesheet xmlnssl=&q
uot;http://www
.w3.org/1999/XSL/Transform"
                xmlns:fo="http://www.w3
.org/1999/XSL/Format"
                version="1.0">
  <xsl:param name="html.stylesheet"
      
select="'/home/gavron/devel/docbook/tests/css-dir/flb.c
ss'"/>
</xsl:stylesheet>
------------------------------------------------------------
----------

I proceed to generate the html document via a:

$ xmlto -vv -m ../fragment.xsl -o ../html-dir html
docfile.xml

Would anyone know whether I can use the same strategy to
specify
alternate css stylesheets that I can switch to on the fly
while browsing
the html document?

Or do I need to specify the alternate CSS style sheets in
the prolog of
each DocBook/XML document?

At this point I modify the XSL fragment above and regenerate
the html
documents every time I want to switch style sheets, which is
slow and
error-prone.  

So I was hoping there might be a better way to do this.

Thanks,
cga

You can emit all necessary link elements by overriding
user.head.content
 template:

<xsl:template name="user.head.content">
  <link .../>
  <link .../>
</xsl:template>

I replaced my XSL fragment by:

------------------------------------------------------------
--------------
<?xml version='1.0'?>
<xsl:template name="user.head.content">
  <link href="walsh.css"
title="walsh" rel="stylesheet"
type="text/css"/>
  <link href="sgh.css" title="alt"
rel="alternate stylesheet"
type="text/css"/>
</xsl:template>
------------------------------------------------------------
--------------

ran:

$ xmlto -vv -m ../xsl-dir/alt1.xsl -o ../html-dir/cheat html
cheat.xml

And I get the following error:

------------------------------------------------------------
--------------

------------------------------------------------------------

Does this mean that he's not finding the
"user.head.content" template
on my system? 

Could this be because I do not have this particular template
installed
on my system, possibly because I'm running this on a system
that's
fairly ancient?

The only html template I found on my system is 

nwalsh/html/titlepage.templates.xsl.

Naturally, it could be just a syntax error in my coding.  I
don't know
XSL so I'm just guessing.

Thanks,
cga

Then you should start by learning at least basics of XSLT
and how to use
it to customize XSL stylesheets:

I took a quick peek and came up with the following fragment
that does what 
I need:

------------------------------------------------------------
-----------------
<?xml version='1.0'?>
<xsl:stylesheet xmlnssl=&q
uot;http://www
.w3.org/1999/XSL/Transform"
                xmlns:fo="http://www.w3
.org/1999/XSL/Format"
                version="1.0">
 <xsl:param name="use.id.as.filename"
select="'1'"/>
 <xsl:param name="admon.graphics"
select="'1'"/>
 <xsl:param
name="admon.graphics.path"></xsl:param>
 <xsl:param name="chunk.section.depth"
select="2"></xsl:param>
 <xsl:param name="html.stylesheet"
   
select="'/home/gavron/devel/docbook/tests/css-dir/free-
templ/fbr.css'"/>
 <xsl:param name="section.autolabel"
select="1"/>
 <xsl:param name="toc.section.depth"
select="5"/>
 <xsl:template name="user.header.content">
  <link href="walsh.css"
title="walsh" rel="stylesheet"
type="text/css"/>
  <link href="bb.css" title="bb"
rel="alternate stylesheet"
