recursion with Muenchean Grouping...

Hi,

I have a source XML file with following general structure:

<root>
	<element>text</element> 	occurence 0 to unbounded
	<element href="URL"/>		occurence 0 to unbounded

	<element>***</element>		*** means a structure like root;
occurence 0 to unbounded		
</root>

I'm trying to develope a generic html visualization for such a XML
document. As you can see by the *** recursion is involved. But I don't
know how to handle it exactly? I think I need another key which groups
the *** root elements? Does anyone have a solution? At the Moment my XSL
looks like that:

Key defined in other XSL:
<xsl:key name="elementtags-by-name" match="*" use="name(.)"/>
