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?
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)
