Ok, let's recap.
Here's the code you quoted:
x2jDefn_nifxml_
1 : 0
for_i. <;._2 (0 : 0) do.
'nm df'=. ':=' splitstring >{.'NB.' splitstring >i
'mn dy'=. dltb each 2 {. ' : ' splitstring df
nm=. dltb nm
if. 0=#dy do. nm x2jChar (3 : mn)
elseif. 0=#mn do. nm x2jElm (4 : dy)
elseif. do. nm x2jElm (3 : (mn;':';dy)) end.
end.
i.0 0
)
'Items'x2jDefn_nifxml_
/ := Result : Result=: ''
compound := cEnd y : x cStart y
add := aEnd y : x aStart y
add := aChr y
)
The consequence of executing this code is something like this:
'/' x2jElm (3 : 0)
Result
:
Result=: ''
)
'compound' x2jElm (3 :0)
cEnd y
:
x cStart y
)
'add' x2jElm (3 :0)
aEnd y
:
x aStart y
)
'add' x2jChar (3 :0)
aChr y
)
Put differently, the x2jElm code runs for the specified elements. The
monadic definition runs for the close of the element and the dyadic
definition runs for the opening element. The '/' gives basically the same
effect as a startDocument/endDocument pair.
Meanwhile, the x2jChar code gets the characters inside the element (inside
the <add> element, in this case).
Does that help? Or am I missing your question?
Thanks,
