Hi,
At 04:40 PM 9/27/2007, was written:
In addition, you have three ways of writing 'answers': ,../answers,
../../answers and ../../../answers. I am sure that while you were
writing it you were thinking something like "it must be possible to
achieve this effect more easily"... There are several ways to code
around the path-depth problem, but the easiest is probably to leave
the path out completely, if you are certain that "answer" elements
are what they are at any level: answer elements (and even if you do
find later that you have different treatment for different
answer-elements, you will simply add a new rule):
I ususally advise against it, but this is a good place to code:
<xsl:apply-templates select=".//answers" />
Actually this should be "ancestor::*/answers", or
"ancestor::*[answers][1]/answers", shouldn't it?
".//answers" will search the subtree below the current node, rather
than look up the tree.
"ancestor::*/answers" will select answers elements from all
ancestors; "ancestor::*[answers][1]/answers" will select only the
closest one. If you think the latter expression is too opaque, you
could also write
(ancestor::*/answers)[last()]
... and then try to explain that. :-)
(Steve, the rest of what Abel says is true: you can refactor your
code into apply-templates select="[the appropriate expression above]"
and lose all those "when" clauses without fear.)
Cheers,
Wendell
