Hi,

I just noticed this question has remained unanswered so far...

Is it possible to repost the problem and include maybe some pseudocode to
demonstrate what the actual concerns / desired results are?

Anyway, your description above reminds me of a way I tackled a similar
scenario, by specifying the count of the children (or any other type of
descendant-nodes) as an attribute on the ancestor at XML creation time. This
could avoid a lot of node-counting while processing the document, just pick
up the value from the attribute.

Best way, I believe, is to use a combination of both, as the above approach
could turn out to be unflexible in some cases.

Hope this helps!

Cheers,

Andreas
