<!--
- XSL transform to extract useful content of a Trac Wiki page.
-
- Django generates weird HTML for ordered lists: it sometimes breaks
- up a single ordered list into multiple adjacent <ol/> elements,
- using the @start attribute to try to make the result look like a
- single ordered list. This looks OK in Firefox but confuses the
- bejesus out of both html2markdown and htmldoc. In some cases this is
- probably unavoidable, but most of the uses of this I've seen look
- gratuitous, and are probably the result of code modulararity issues
- in Django.
-
- So we try to clean this up, by merging adjacent <ol/> elements where
- we can. The merge incantation is an adaptation of:
-
- http://stackoverflow.com/questions/1806123/merging-adjacent-nodes-of-same-type-xslt-1-0
-
- There may be a more efficient way to do this, but I don't think
- we care, and this seems to work.
-
- Original author's explanation:
-
- The rather convoluted XPath expression for selecting the following
- sibling aaa nodes which are merged with the current one:
-
- following-sibling::aaa[ # following 'aaa' siblings
- not(preceding-sibling::*[ # if they are not preceded by
- not(self::aaa) and # a non-'aaa' node
- not(following-sibling::aaa = current()) # after the current node
- ])
- ]
