Re: Nesting a flat XML structure

Heres a much simplified, but representative example of typical source XML:

<doc>

<p style="h1">title text</p>

<p style="para">body text</p>

<p style="para">body text</p>

<p style="bullet_level1">list text</p>

<p style="bullet_level1">list text</p>

<p style="bullet_level2">list text</p>

<p style="bullet_level2">list text</p>

<p style="bullet_level2">list text</p>

<p style="h2">title text</p>

<p style="para">body text</p>

<p style="para">body text</p>

</doc>

I need to generate the nested structure to look like similar to this (again much simplified):

<doc>

<section>

<title>title text</title>

<p>body text</p>

<p>body text <ul>

<li>list text</li>

<li>list text<ul>

<li>list text</li>

<li>list text</li>

<li>list text</li>

</ul>

</li>

</ul>

</p>

<section>

<title>title text</title>

<p>body text</p>

<p>body text</p>

</section>

</section>

</doc>

There is no way to know in advance the level of nesting that may be needed. The rules for nesting are provided by a separate mapping file. The mapping file is used as the input to generate a document specific xslt file that handles element naming and adds all of the necessary attributes. The format and content of that mapping file are under my control but the source documents are not.

My initial efforts used xsl:for-each-group with group adjacent to identify and nest the first level and that works nicely, but Ive got myself tied-up in knots trying to work out how to make it work for any further nesting. Perhaps Im overthinking it? I tried to create a recursive template to do the work, but thats where I got stuck.
