[docbook-apps] removing elements from bookmarks (fop1)

[robert <rp.info@gmail.com>]

Hi,

I have a book with the following structure:

<book xml:id="b1">

  <article xml:id="a1"/>

  <article xml:id="a2"/>

</book>

I use fop1 extension to generate bookmarks. The xsl-fo transforms generate something like this:

<fo:bookmark-tree>

  <fo:bookmark internal-destination="b1"/>

  <fo:bookmark internal-destination="a1"/>

  <fo:bookmark internal-destination="a2"/>

</fo:bookmark-tree>

Now, I would like the list to contain only articles, i.e.

<fo:bookmark-tree>

  <fo:bookmark internal-destination="a1"/>

  <fo:bookmark internal-destination="a2"/>

</fo:bookmark-tree>

How can I block the mechanism for book elements?

Thanks,

Robert
