Hi
Upon recommendation from this list, I initially used XPathDirectoryGenerator,
but it was too slow for online use. Since I know when a file is changed, I
call the following URL which produces one large XML file with the contents of
all files in the directory.
A FileChainingGenerator would probably be a better solution, but here I have a
full Cocoon XML/XSLT solution. Not very elegant, but at least it works. If
somebody comes up with something better, I'll be happy ;-)
Cheers Martin

The sitemap entry:
<!-- Update the (cached) list of all files and write it to the file allfiles.xml -->
<map:match pattern="allfiles-update">
<map:generate type="directory" src="docs">
<!-- regexp to exclude all files that have characters after ".xml" -->
<!-- e.g. auto-save files -->
<map:parameter name="exclude" value=".*\.xml.+"/>
</map:generate>
<map:transform src="stylesheets/lib/aggregate.xsl"/>
<map:transform type="xinclude"/>
<map:transform src="stylesheets/lib/sourcewrite.xsl">
<map:parameter name="sourcefile" value="docs/allfiles.xml"/>
</map:transform>
<map:transform type="write-source"/>
<map:serialize type="xml"/>
</map:match>

The stylesheet aggregate.xsl (makes list of XLinks)
<?xml version="1.0" encoding="utf-8"?>
<!-- =======================================================================
Make include tags for all files given in the input (from DirectoryGenerator)
======================================================================= -->
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:dir="http://apache.org/cocoon/directory/2.0";
xmlns:xi="http://www.w3.org/2001/XInclude";
version="1.0">
<xsl:output method="xml"/>
<xsl:template match="/">
<allglaciers>
<xsl:apply-templates/>
</allglaciers>
</xsl:template>
<xsl:template match="dir:directory">
<xsl:for-each select="dir:file">
<xsl:sort select="@name"/>
<xi:include parse="xml" href="cocoon:/{../@name}/{@name}#xpointer(/*)" />
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
----
The stylesheet sourcewrite.xsl (makes the sourcewriting tags)
<?xml version="1.0" encoding="utf-8"?>
<!-- =======================================================================
Make source-writing tags
======================================================================= -->
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:param name="sourcefile"/>
<xsl:output method="xml"/>
<xsl:template match="/">
<source:write xmlns:source="http://apache.org/cocoon/source/1.0";>
<source:source><xsl:value-of select="$sourcefile"/></source:source>
<source:fragment>
<xsl:copy-of select="*"/>
</source:fragment>
</source:write>
</xsl:template>
</xsl:stylesheet>
