A general question regarding this sort of handling of duplicates (I'm not
sure if it's in the faq, but I couldn't find an explicit mention) - am I
correct in thinking that if you have to worry about white space in the
values you're comparing, then you have to use keys?
Having to deal with things like this:
with a desired output of
doing something like
<xsl:if test="not(. = preceding-sibling::bar)"><xsl:text>
doesn't work because of the white space. This
not(normalize-space(.) = preceding-sibling::bar)
doesn't work because it only normalizes the context node, and this
not(normalize-space(. )= normalize-space(preceding-sibling::bar))
doesn't work because it's only comparing the context node and the first node
in doc order of the preceding-sibling access.
I have handled this by defining a key from the space normalized value of the
element plus the document position of its parent (to duplicate the
preceding-sibling behaviour) and then checking if the context node is the
first in its key group, but wondered if there was some combination of
preceding-sibling and normalize-space that would do what I mean.
I did find this in the archive - which seems to indicate that there isn't,
yet, any way to do this -
