Hi David,
The last week an amazin brown arrive me, the problem is the same:
I have this xml:
<modul>
<unit id="1">
<subunit>Rupturas</subunit>
<sub-subunit>sistema </sub-subunit>
<sub-subunit>incertidumbre</sub-subunit>
<subunit>Megatendencias</subunit>
<sub-subunit>Caracterización</sub-subunit>
<sub-sub-subunit>1.2.1.1.</sub-sub-subunit>
<p>Text 1211</p>
<param>Text 2 1211</param>
<sub-sub-subunit>1.2.1.2.</sub-sub-subunit>
<sub-sub-subunit>1.2.1.3.</sub-sub-subunit>
<sub-subunit>Vectores</sub-subunit>
<sub-sub-subunit>1.2.2.1.</sub-sub-subunit>
<sub-sub-subunit>1.2.2.2.</sub-sub-subunit>
<sub-sub-subunit>1.2.2.3.</sub-sub-subunit>
<subunit>Perspectivas</subunit>

<sub-sub-subunit>1.3.1.1.</sub-sub-subunit>
<sub-sub-subunit>1.3.1.2.</sub-sub-subunit>
<sub-subunit>controversia</sub-subunit>
<sub-sub-subunit>1.3.2.1.</sub-sub-subunit>
<sub-sub-subunit>1.3.2.2.</sub-sub-subunit>
</unit>
<unit id="2">
<p>Desafíos sociolaboral</p>
<subunit>Cantidad</subunit>
<p>Text Cantidad</p>
<sub-subunit>riqueza</sub-subunit>
<sub-subunit>paraíso</sub-subunit>

<sub-subunit>panorama a las perspectivas</sub-subunit>
<subunit>Calidad</subunit>
<sub-subunit>Polarización</sub-subunit>
<sub-subunit>La cara</sub-subunit>
<sub-subunit>La cruz</sub-subunit>
<sub-subunit>Precarización</sub-subunit>
<subunit>experiencia</subunit>
<sub-subunit>Ejes</sub-subunit>
<sub-subunit>Condiciones</sub-subunit>
<sub-sub-subunit>2.3.2.1.</sub-sub-subunit>
<sub-sub-subunit>2.3.2.2.</sub-sub-subunit>
<sub-sub-subunit>2.3.2.3.</sub-sub-subunit>
<subunit>paradigma</subunit>
<sub-subunit>civilización</sub-subunit>
<sub-subunit>empleísmo</sub-subunit>
<sub-subunit>Agenda</sub-subunit>
</unit>
</modul>
And I have to convert in a hierarchial xml structure into the unit
tag, with this conditions:
- Between tag can exists another tags, this tags belongs to the
preceding-sibling.
- The hierarchi is: unit, subunit,sub-subunit and sub-sub-subunit.
Result file and solution:

2006/7/24, Georg Hohmann <georg(_dot_)hohmann(_at_)gmail(_dot_)com>:
Dear XSLT-Community,
i have problem with some "strange" type of data which i have to
convert to a hierarchical xml structure.
My source is a huge xml file which represents a decimal
classifikation. It contains so called documents, where each document
represents one node of the classification. Furthermore each documents
shows the direct parents of a node. It's a structure like this
(example taken from http://www.udcc.org):
...
<document>
<tag1>3</tag1>
<tag1a>Social Sciences</tag1a>
</document>
<document>
<tag1>3</tag1>
<tag1a>Social Sciences</tag1a>
<tag2>32</tag2>
<tag2a>Politics</tag2a>
</document>
<document>
<tag1>3</tag1>
<tag1a>Social Sciences</tag1a>
<tag2>32</tag2>
<tag2a>Politics</tag2a>
<tag3>326</tag3>
<tag3a>Slavery</tag3a>
</document>
...
As you can see there is no hierarchical information in it instead of
the names and the sequence of the tags. In my real data i have up to 9
levels, but not every time. My result should look like this (or
something similar):
...
<node id="3" name="Social Science">
<node id="32" name="Politics">
<node id="326" name="Slavery"/>
</node>
</node>
...
I have simply no idea what to start with to archive this result. I
guess the first step would be to get rid of all those redundant
content, but i don't know how. And i even can't figure out how to
build the hierachichal structure the same time.
Has anyone a good starting point for this?
