I have written an xsl file that parses the individual "Script" nodes
in the ScriptCatalog and it works fine.... the problem recently is
that FileMaker has now added the ability that the Script Element I am
looking for in the ScriptCatalog might be nested within a Group or
SubGroup or any other sub nesting ...

Ken already emailed me a suggestion where I could just use //Script to
get all the script elements... but the problem with that is the
CustomMenuCatalog might also have MenuItems with Script elements.

But that now only gets me to the first Script if it is not within a
group.

Any suggestions on how I can get the complete list of all the Script
entries even if they are nested 1, 2, 3, ...n levels?
