#1152 epub files fail to create for some components

[David Gardiner]

epub files fail to generate correctly when I transform Docbook 'glossary' and 'index' chunks. The output file - which should be the mimetype file that contains only one line: <?xml version="1.0" encoding="UTF-8"?> - instead also contains a DTD and HTML code of the transformed chunk. Also, there is no HTML file generated in folder OEBPS which should contain the HTML code - only 'content.opf' and 'toc.ncx' are created in OEBPS.

I am using 1.76.1 stylesheets, and transforming using Saxon 6.5.5 through oXygen XML Editor version 12. I have changed only two parameters for the epub transformation:
epub.metainf.dir : /META-INF/
epub.oebps.dir : /OEBPS/

The mimetype file contains this code:
<?xml version="1.0" encoding="UTF-8"?>

Input file to transform

[David Gardiner]

I've partly succeeded in generating a glossary chunk. I had a close look at the stylesheet epub/docbook.xsl - there is some code under "<xsl:template name="chunk" priority="1">" that states what components are specified as chunks (and therefore processed when transformed). Both glossary and index components are treated as chunks IF they match several criteria. For glossary:
<xsl:when test="local-name($node)='glossary' and (local-name($node/parent::*) = 'article' or local-name($node/parent::*) = 'book' or local-name($node/parent::*) = 'part' )">1</xsl:when>

This indicates that a glossary will only be transformed IF its parent is a book, article or part. Sure enough, when I transformed a book with a glossary include, I got a correctly formatted HTML file for the glossary. I could not, however, get the correct HTML files if I transformed a glossary chunk on its own (ie. where glossary was the root node).

Can the stylesheets please be changed so that you can transform glossary and index for individual testing, without the need to first include these in a book component? I can't fathom why you wouldn't want this functionality anyway.
