After a fair bit of tinkering, and examining the example at the doc,
"xml sel -T -t -m /xml/table/rec -s D:N:- "@id" -v
"concat(@id,'|',numField,'|',stringField)" -n xml/table.xml", I
finally came up with something that works:
[12:31 PM] 160Mb$ xmlstarlet sel -T -t -m /mnemosyne/item -s A:N:-
'@e' -v "concat ('Easiness=',@e,'||',Q,'|',A)" -n default.xml
I was a little shocked that 700 of my cards were at 1.300.
