Jens,
Could I do this right after database creation and it would actually CHANGE
the node names so that my queries could all still references the lower case
node names? (that's what it looks like it's doing but I just wanted to
confirm it).
I need to do it for 3 node names, can it be done in one "for" loop?
I don't mind taking the hit at database creation time as opposed to query
time.
Thanks!
David

Hi David,
for preprocessing you could use something like
for $i in //*
return rename node $i as lower-case(name($i))
to rename all nodes to their lower-case equivalent. If you only want to
process lyrics-nodes of all variations, insert Dirk's predicate to `//*`.
Sadly the full-text index which offers case insensitivity doesn't include
tag names, so you can't use this either.
Kind regards from Lake Constance, Germany,
Jens
