Re: [xsl] managing footnotes in nested elements

2007-09-24 04:22:19


1. I want to test whether a particular table node (the context node)
contains any descendant footnote elements where (a) the footnote "level"
attribute has the value "table", and (b) the footnote's nearest table
ancestor is the context node.

.//footnote[(_at_)level='table'][generate-id(ancestor::table[1])=generate-id(current())]

2. The next step is to generalise this test so that the context node may be
anything, i.e. for the current node, X say, there is at least one footnote
element with its level attribute = "X", and that footnote's nearest ancestor
X is in fact the context node X.

.//footnote[(_at_)level='table'][generate-id(ancestor::*[name()=name(current())][1])=generate-id(current())]

but it's not working.
mainly because you are using . (which is the fotnote element being
tested) not current() (which is the current node at the start of the
expression)


Although looking at your original post I wouldn't do this test at all.

You only need to look all the way down at footnotes and then look back
to check you haven't gone inside a nested table because you were too
agressive in collecting footnotes in the first place.


so instead of

   <xsl:apply-templates
       select="descendant::footnote[(_at_)level=$local]"
        mode="footnote"/>


I'd (perhaps) do

   <xsl:apply-templates  select="*"  mode="footnote"/>

On most elements you just want to recurse (on elements, not text) so:

<xsl:template match="*" mode="foornote">
   <xsl:apply-templates  select="*" mode="footnote"/>
</xsl:template>

on table elements you want to stop looking (you'll handle the nested
table later)

<xsl:template match="table" mode="foornote"/>


and foootnote elements you want to do whatever it is you want to do:

<xsl:template match="footnote[(_at_)level='footnote']" mode="foornote">
  make a footnote
</xsl:template>
