Hi Rick,

Compared to the pain using XSLT1 for a task which XSLT2 can easily handle, the
pain you have to go through if you are forced to change a nice working XSLT2
solution down to XSLT1 is a real PITA.

But anyhow, I know that sometimes we are forced to do ugly stuff. I would not
be trying to use xsl:key for that problem, as keys are more of an index across
a full document and in your situation everything depends on the order of
elements. In XSLT2 you would use xsl:for-each-group, which in XSLT1 sometimes
can be kind-of replicated by "tree walking"
<http://www.dpawson.co.uk/xsl/sect2/N4486.html#d5510e1105>.

As in your example the same class attribute value maybe used for a level 1 or
level 2 list item, it might also be a good idea to do some preprocessing,
because otherwise some XPaths may become really long. I guess I would try to
separate the logic of finding the correct list item level from the step of
adding the required <ul>.

Good luck,

- Michael
