Re: [xsl] Grouping Adjacent Elements in XSLT 1.0 and Duplicates

Hi Joe,

The problem is that in the calling template, you're applying templates
to all the <ol_li> elements (in no mode). The first list is being
generated due to templates being applied to the first <ol_li> element,
the second because of templates being applied to the second <ol_li>
element and so on.

To use the kind of recursion that you're using to construct the lists,
you need to just apply templates to the first <ol_li> in each list. So
in the calling template, you need something like:

  <xsl:apply-templates
    select="para |
            ol_li[not(preceding-sibling::*[1][self::ol_li])]" />

Alternatively, you could do the whole thing using step-by-step
recursion, in which case you need to just apply templates to the first
of the <para> or <ol_li> elements:

  <xsl:apply-templates select="*[1]" />

but build in recursion within the <para> template as well:

<xsl:template match="para">
  <p><xsl:apply-templates /></p>
  <xsl:apply-templates select="following-sibling::*[1]" />
</xsl:template>

Cheers,

Jeni
