RE: Count Ancestors Up To But Not Including a Given Ty
Hi, I'm transforming DITA too. Yes, it's quite wide open in some repects. To keep track of how deeply nested I am, I initialize tunnel variables (such as OLdepth and Uldepth) at the topic element, and increment them when I hit elements such as ol ($OLdepth + 1) or ul ($ULdepth + 1). When you are in the li element, include the param statements, remembering to always specify tunnel="yes". Check the parent to see which value you want. I think this is what tunnel variables are for.

In DITA, as in many doctypes, you can have nested lists of the form: <ol> <li> <ol> <li> </li> </ol> </li> </ol> As well as an intermixing of different list types, e.g.: <ol> <li> <ul> <li> <ol> <li> What I need to do is determine, for a given li, its depth of nesting within unbroken ancestry of a given list type. Thus, int the first example, the deepest li is a level 2 because it has two ancestor <ol> elements with no intervening <ul> (or other non-list element that might occur within <li> and itself contain a list). In the second example, the deepest <li> is a level one because there is an intervening <ul> between the two <ol> ancestors. I can't for the life of me figure out either a single expression or a recursive function that will return the correct answer. What bit of logic am I failing to see? I am using XSLT 2.
