All,
I have a conditional expression that checks to see if the current node
has any ancestor whose xml:id attribute matches a string
\xmldoifelse{#1}{ancestor::div[@xml:id='apr_engl']}
What I need is a test to see if the current node has any ancestor
whose xml:id attribute _contains_ a substring. Something like this:
\xmldoifelse{#1}{ancestor::div[ @xml:id contains('_engl')]}
trying this:
\xmldoifelse{#1}{ancestor::div[ contains(@xml:id, '_engl')]}
got me this error:
! LuaTeX error < local expr = xml.expressions...>:3: bad argument
#1 to 'contains' (string expected, got nil)
any suggestions?
Jon

is there always an id? if not:
@xml:id and contains(@xml:id,'_engl')
small test file needed
(you can run with \enabletrackers[xml.parse,xml.path] to see how it ends
up)

Hans et alia,
Thanks for helping out with the right xpath expression. That was
indeed the problem: div elements in the ancestor axis that had no
xml:id attribute. Unfortunately, this doesn't solve my root problem.
I have a tei/xml marked up text with English and Arabic sections. For
each ref tag in the english section I want to place a \footnote. For
the corresponding ref in the Arabic section I want to place a \note
pointing to the same footnote as the corresponding English ref. The
minimal example appended below accomplishes this, but when I try to
apply this solution to my full text, this solution fails: I get ?? in
place of the references in the arabic, lua stats reports:
mkiv lua stats > cross referencing - 56 identified, 56 unknown
and I get repeated errors of the following sort:
xml > lpath > 1 : ex :
@xml:id==string.sub('#N020-18', 2) ->
(ll.at and ll.at['xml:id'])==string.sub('#N020-18', 2) ! Missing
number, treated as zero.
which is where, I presume, the ?? references are coming from
minimal example follows (\environment ara-sty not included)
Any insights you may have would be gratefully received.
Jon
(PS I suspect that the multiple errors associated with this problem
are what's causing --result renaming to fail)

lua error with sub .. not sure what you want t o test here
indeed an error will prevent the multipass file to be saved (feature)

Thanks Hans, It's good to know the --result problem is not a bug, but
a feature. My problem then arises from my use of \note as opposed to
\footnote. In processing a <ref> tag in the xml, I need to test if the
current ref node has an ancestor <div> with attribute:
@xml:id='apr_engl'. If it does, I need to create a \footnote whose
text comes from a <note> element with attribute xml:id='N020-18', if
it does not, I need to create a \note whose reference number
corresponds to the one created by \footnote and thus points to the
same footnote contents:
<div xml:id='apr_arab'>
<...>
<ref target="#N020-18">referenced text</ref>
<...>
</div>
<div xml:id='apr_engl'>
<...>
<ref target="#N020-18">referenced text</ref>
<...>
</div>
...
<note xml:id='N020-18'>footnote contents</note>
To result in:
arabic text (1)
english text (1)
(1) footnote content
Currently I'm getting:
arabic text ??
english text (1)
(1) footnote content
Document order problem maybe?
thanks,
Jon

probably a too complex solution ... this is an alternative:
\startbuffer[test]
<text>
<div type='a'>
a <ref target="#N01"> a </ref>
a <ref target="#N02"> a </ref>
</div>
<div type='b'>
b <ref target="#N01"> b </ref>
b <ref target="#N02"> b </ref>
</div>
<div type='c'>
<note xml:id="N01">ONE</note>
<note xml:id="N02">TWO</note>
</div>
</text>
\stopbuffer
\startxmlsetups xml:somesetups
\xmlsetsetup{#1}{text|div|ref|note}{xml:*}
\xmlsetsetup{#1}{div[@type='a']}{xml:div:a}
\xmlsetsetup{#1}{div[@type='b']}{xml:div:b}
\xmlsetsetup{#1}{div[@type='c']}{xml:div:c}
\stopxmlsetups
\xmlregistersetup{xml:somesetups}
\startluacode
function document.preprocess()
local notes = { }
for e in lxml.collected("main","note") do
notes[e.at["xml:id"]] = 0
end
for e in lxml.collected("main","ref") do
local target = e.at["target"]
if target then
local id = string.gsub(target,"^#","")
local n = notes[id]
if n then
n = n + 1
e.at.footnote = n
notes[id] = n
e.at["xml:id"] = id
end
end
end
end
\stopluacode
\startxmlsetups xml:text
\ctxlua{document.preprocess()}
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:div:a
\par[div a]\par
\xmlflush{#1}
\par[div a]\par
\stopxmlsetups
\startxmlsetups xml:div:b
\par[div b]\par
\xmlflush{#1}
\par[div b]\par
\stopxmlsetups
% \startxmlsetups xml:div:c
% \par[div c]\par
% \xmlflush{#1}
% \par[div c]\par
% \stopxmlsetups
%
% \startxmlsetups xml:note
% [note \footnote[\letterhash\xmlatt{#1}{xml:id}]{\xmlflush{#1}}]
% \stopxmlsetups
%
% \startxmlsetups xml:ref
% [ref : \note[\xmlatt{#1}{target}] ]
% \stopxmlsetups
\startxmlsetups xml:div:c
\stopxmlsetups
\startxmlsetups xml:note
\stopxmlsetups
\startxmlsetups xml:ref
\doifsomething{\xmlatt{#1}{footnote}} {
\doifelse{\xmlatt{#1}{footnote}} {1} {
[footnote \footnote[\xmlatt{#1}{xml:id}]{\xmlflush{#1}}]
} {
[note \note[\xmlatt{#1}{xml:id}]{\xmlflush{#1}}]
}
}
\stopxmlsetups
\starttext
\xmlprocessbuffer{main}{test}{}
\stoptext
(if it works ... wikify it)

Hans,
Thanks for this. It's almost what I need. I truly appreciate the
effort, and it does give me some ideas about things to try.
However, if I change your example buffer slightly (for clarity) to this:
<text>
<div type='a'>
arab <ref target="#N01"> foo </ref>
arab <ref target="#N02"> bar </ref>
</div>
<div type='b'>
english <ref target="#N01"> eggs </ref>
english <ref target="#N02"> ham </ref>
</div>
<div type='c'>
<note xml:id="N01"> note text ONE</note>
<note xml:id="N02"> note text TWO</note>
</div>
</text>
your code runs and gives me this:
[div a]
arab [footnote1] arab [footnote2]
[div a]
[div b]
english [note1 eggs ] english [note2 ham ]
[div b]
____
1 foo
2 bar
but what I'm trying for is this:
[div a]
arab [ foo1 ] arab [ bar2 ]
[div a]
[div b]
english [ eggs1 ] english [ ham2 ]
[div b]
____
1 note text ONE
2 note text TWO
