Hi all,
below is a slightly silly example that demonstrates a problem I’m having: I
want to process (in Lua) the xml element “b” only when it has an attribute
“display” set. This works, but elements without the attribute leave spurious
spaces in the pdf output. The workaround I’m currently using is
if xml.attribute(e, "./", "display", "") ~= "yes" then
context.unskip()
else
…
but that seems like a kludge. Is this expected behavior, or should this be
fixed?
Thanks
Thomas
\startbuffer[test]
<a>
<b display="yes">test</b>
<b>test</b>
<b>test</b>
<b>test</b>
<b display="yes">test</b>
<b display="yes">test</b>
<b>test</b>
</a>
\stopbuffer
\startxmlsetups xml:testsetups
\xmlsetsetup{\xmldocument}{a|b}{xml:*}
\stopxmlsetups
\xmlregistersetup{xml:testsetups}
\startluacode
function xml.functions.b(e)
xml.strip(e, "/", nolines, anywhere)
if xml.attribute(e, "./", "display", "") == "yes" then
context.space()
context("/")
context.space()
lxml.flush(e)
end
end
\stopluacode
\startxmlsetups xml:a
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:b
\xmlfunction{#1}{b}
\stopxmlsetups
\starttext
\xmlprocessbuffer{main}{test}{}
\stoptext
