[relaxng-user] rng analysis

[David Rosenborg]

Hi Dave,

Have you tried using a simplified rng schema as input to your stylesheet?
If not, you could try it, it will make things a lot easier. I've used 
this method
to successfully generate <xsl:preserve-space> and <xsl:strip-space>
declarations from rng schemas.

The stylesheet uses rules along these lines:

  <xsl:template match="rng:element [
      descendant::*[
      (self::rng:data or self::rng:text or
       self::rng:value or self::rng:list) and
      not(ancestor::rng:attribute)]]
      ">
       <!-- Preserve space in this element -->
  </xsl:template>

Depending on your required accuracy of the output, the outline above might
be too coarse grained, but a few more templates and predicates should
narrow it down sufficiently.

relaxng.org has links to tools that can perform the simplification step 
(e.g. rng2srng).

Cheers,

David
