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?

\startxmlsetups xml:a \ignorespaces \xmlflush{#1} \removeunwantedspaces \stopxmlsetups \startxmlsetups xml:b \ignorespaces \xmlfunction{#1}{b} \removeunwantedspaces \stopxmlsetups

Thanks

Thomas
