Here is my desired output:

<level2>

<para>ABC</para>

</level2>
<level2>

<level3>
<text>
<para>I belong to the new list 3list 3.</para>

<level2>
<text>
<para>I belong to list 2 again</para>
</text>
<level3>
<text>
<para>another list 3</para>
</text>
<level4 id="S022496B8">
Where does that id come from?
<text>
<para>222</para>
</text>
</level4>
</level3>
Isn't one level3 missing here, from
<!-- I belong to lsit 3 now-->
<litem>333</litem>
</level2>
</level1>
The idea is that every 'litem' element counts as a 'levelX'.
Here is an attempt to solve that with XSLT 2.0:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:mf="http://example.com/2009/mf";
exclude-result-prefixes="xs mf"
version="2.0">
<xsl:output method="xml" indent="yes"/>
<xsl:function name="mf:group" as="element()*">
<xsl:param name="elements" as="element()*"/>
<xsl:param name="level" as="xs:integer"/>
<xsl:for-each-group select="$elements/*" group-starting-with="litem">
<xsl:element name="level{$level}">
<text>
<para>
<xsl:value-of select="."/>
</para>
</text>
<xsl:sequence select="mf:group(current-group() except ., $level
+ 1)"/>
</xsl:element>
</xsl:for-each-group>
</xsl:function>
<xsl:template match="/">
<xsl:sequence select="mf:group(list1, 1)"/>
</xsl:template>
</xsl:stylesheet>
Using Saxon 9 it produces the following result:
<level1>
<text>
<para>000</para>
</text>
<level2>
<text>
<para>123 </para>
</text>
<level3>
<text>
<para>ABC</para>
</text>
</level3>
<level3>
<text>
<para>666</para>
</text>
</level3>
</level2>
<level2>
<text>
<para> 999 I belong to list 2</para>
</text>
</level2>
<level2>
<text>
<para> I belong to list 2</para>
</text>
<level3>
<text>
<para> I belong to the new list 3</para>
</text>
</level3>
</level2>
<level2>
<text>
<para> I belong to list 2 again</para>
</text>
<level3>
<text>
<para> another list 3</para>
</text>
<level4>
<text>
<para>222</para>
</text>
</level4>
</level3>
<level3>
<text>
<para>333</para>
</text>
</level3>
</level2>
</level1>
It does not generate the id as I don't know where that should come from
and it does generate a <text><para>...</para></text> for the 'litem'
element child of 'list1' as I did not try to implement different
treatment for the first level.
