Subject: RE: [docbook] Select chunk content from user.head.content template

Thanks Bob, I never though of using the chunk template :P

The for-each selector ended up as 

<xsl:for-each select=".//indexterm[$is.chunk= 1] 
                     |(indexterm|*[not(self::section or self::book)]//indexterm)[$is.chunk = 0]">

same as yours, but excluding book nodes and reversed the is.chunk selector exclusions. Does this seem logical by you?

Hi Morten,
There is a utility template named "chunk" that can be used to test if a
given node is a chunk element.  You could use it to check the first child

<xsl:variable name="chunk.children">
  <xsl:call-template name="chunk">
    <xsl:with-param name="node" select="section[1]"/>

The $chunk.children will have a value of 1 if that section is a chunk, or 0
otherwise.  Then you can use that in the select statement:

<xsl:for-each select=".//indexterm[$chunk.children = 0] |
|*[not(self::section)]//indexterm)[$chunk.children = 1]">

The select statement combines two parts that are mutually exclusive.
The first part selects all the indexterms, but qualifies them with a boolean
expression to exclude all of them if $chunk.children = 1.
The second part selects indexterms that are either immediate children of the
current section, or a descendant of any child element that is not a section.
This part is qualified by the opposite boolean expression, so only one or
the other part is used.

I didn't test this, so let me know if it doesn't work for you.  There might
be a glitch that I'm not seeing.
