nested groups from flat file

Hi,

I'm using XSLT 2.0 and Saxon 9.3.
I have a flat markup and need to give it some structure.

Examplary markup

<a>...</a>
<b>...</b>
<c>...</c>
<d>...</d>
<e>...</e>
<d>...</d>
<d>...</d>

Desired result:

<layera>
      <a>...</a>
      <layerb>
             <b>...</b>
             <layerc>
                <c>...</c>
                <layerd>
                        <d>...</d>
                        <e>...</e>
                </layerd>
                <layerd>
                        <d>...</d>
                </layerd>
                 <layerd>
                        <d>...</d>
                </layerd>
        </layerc>
     </layerb>
</layera>

So I know where a new "layer" oft he strcture starts (it's a little more
complicated but I simplified it to fit in an email) but I don't know how to
wrap things like this.

I've tried nested groupings while always checking if there is a nother layer
following but that seems very cumbersome and not elegant at all.

I've also tried matching the starts of layers and working with modes to wrap
things but that get's very messy very quick and doesn't really work as
intended either.

Is there a best practive to do this ? Maybe a feature of for-each-group that
I'm unaware of ?

regards
