Re: [xsl] Duplicate output for nested list Help

I have a few comments to make regarding style, in addition to what I 
think is the answer to your question.

I note in your data that <strong> and <ol> are siblings.

So in your XSLT when you test that you have an <ol> child, you 
process *all* children of <li> which reprocesses your <strong> a second time:

You probably only want <xsl:apply-templates select="ol"> in order not 
to process other siblings.

But I suspect the structure of your stylesheet could be changed to do 
more matching so as to reduce the amount of special casing that you 
are doing.  But it is difficult to advise without seeing more of your 
specification.

Regarding style, this technique of checking "what am I" is 
particularly frowned upon in stylesheet:

>                 <xsl:variable name="nodeName" select="name()"/>
> ...
>                 <xsl:if test="$nodeName = 'li'">

... where you should be using test="self::li" ... which, actually, 
you are using elsewhere in your stylesheet:

>            <xsl:apply-templates select="@* | node()[not(self::ol)]">

And your depth counting may be able to be addressed with counting 
nodes in the source node tree declaratively rather than imperatively 
maintaining depth counters in raw stylesheet code.

I hope this is helpful.
