Dear Martynas,

This not the complete solution that you asked for, with lookups in styles.xml and with HTML generation, but at least it deals with outline gaps. I put it in a function that takes all your nodes and groups them by the lowest outline level number present (which corresponds to the highest hierarchy level...), and then recursively groups the groups by the next level that is available. You can also find it on http://github.com/gimsieke/oo2teilite-xslt2/blob/master/oo2teilite.xsl

Gerrit

<xsl:function name="letex:hierarchize-by-outline" as="node()*"> <xsl:param name="nodes" as="node()*" /> <xsl:param name="outline-level" as="xsd:double*" /> <xsl:choose> <xsl:when test="empty($outline-level)"> <xsl:sequence select="$nodes" /> </xsl:when> <xsl:otherwise> <xsl:for-each-group select="$nodes" group-starting-with="text:h[@text:outline-level = $outline-level]"> <xsl:choose> <xsl:when test="current-group()[1]/@text:outline-level = $outline-level"> <xsl:text>
</xsl:text> <div type="Heading_{$outline-level}"> <head> <xsl:copy-of select="current-group()[1]/node()" /> </head> <xsl:variable name="new-nodes" select="current-group()[position() gt 1]" as="node()*" /> <xsl:sequence select="letex:hierarchize-by-outline($new-nodes, min($new-nodes/@text:outline-level))" /> </div> </xsl:when> <xsl:otherwise> <xsl:sequence select="letex:hierarchize-by-outline(current-group(), min(current-group()/@text:outline-level))" /> </xsl:otherwise> </xsl:choose> </xsl:for-each-group> </xsl:otherwise> </xsl:choose> </xsl:function>

Sorry, you're right. I can make a simplified test case:

ODT (styles.xml):
<style:style style:name="Heading_1" text:outline-level="1"/>
<style:style style:name="Heading_2" text:outline-level="2"/>
<style:style style:name="Heading_3" text:outline-level="3"/>
<style:style style:name="Heading_4" text:outline-level="4"/>

XHTML:
<p class="Heading_1">1</p>
...
<p class="Heading_3">1.1.1</p>
...
<p class="Heading_1">2</p>
...
<p class="Heading_2">2.1</p>
...
<p class="Heading_3">2.1.1</p>
...
<p class="Heading_2">2.2</p>

Desired outline (also what OpenOffice.org produces):
1
   1.1.1
2
   2.1
     2.1.1
   2.2

But if you process it recursively level after level as I described, you get:
1
2
   2.1
     2.1.1
   2.2

Notice 1.1.1 is missing, because 1.1 is missing as well -- in other
words, there is a gap between levels 1 and 3.

Does that make it clearer? How would you process such outline that all
the levels are included, no matter there are gaps between them?
