Hello!
Processing XML I want to manipulate content of XML elements inside Lua.
I can define the Lua function xml.functions.name
<http://xml.functions.name>(t), where processing happens, and use the
command \xmlfunction{#1}{name} to pass the current node #1from ctx to
lua as described in the xml-mkiv.pdf manual. To access the element
content xml.text(t,"/element") Lua function is used.
However, using the same function xml.text("#1",/element) directly inside
Lua doesn't work for me. Node #1 is available, but not the content of
/element.
In your lua fragment, node #1 is available as "xml:name::4" or
"xml:name::6", but not as a lua table.
When node #1 is passed to a \xmlfunction, the function gets a lua table
as argument.
To write direct lua code instead of a xmlfunction you'd need a function
to transform those "xml:name::..." into the lua tables representing the
xml elements in the xml tree.
Which is what \xmlfunction does, so I wouldn't expect any performance gain.
