Subject: Equivalent for (tree-before?) From: Chris Maden <crism@xxxxxxxxxxx> Date: Thu, 29 Jul 1999 12:23:45 -0400 (EDT) |
I need to check which footnotes come before a page break: (let ((fn-list (select-elements (descendants (current-node)) (norm "footnote"))) (last-break-pi (node-list-last (find-break-pis)))) (process-node-list (node-list-filter (lambda (cand) (tree-before? last-break-pi cand)) fn-list))) I've implemented the reference functions from ISO/IEC 10179, and it's *really* slow (presumably because of (sort-in-tree-order)). Is there a faster way to do this? In this case, I can use a variant of (sort-in-tree-order) that only gets the (subtree) for the current context (I only need to do this inside DocBook <sidebar>s), but it would be nice to know another way. When only elements are involved, I just use (all-element-number), but that doesn't work when one of the nodes is not an element.
