Eric, that's the correct behavior. Your pattern matches the empty string
anywhere, including at the start of your string. You can get the behavior
you're looking for by matching empty strings not at the beginning or end of a
word, using the expression '\B'.
declare variable $alphabet := tokenize('abcdefghijklmnopqrstuvwxyz', '\B');
for $x in $alphabet
return concat('[', $x, ']')
=> [a] [b] [c] [d] [e] [f] [g] [h] [i] [j] [k] [l] [m] [n] [o] [p] [q] [r] [s]
[t] [u] [v] [w] [x] [y] [z]

Subject: [MarkLogic Dev General] tokenize returns empty string on "" pattern
declare variable $alphabet := tokenize('abcdefghijklmnopqrstuvwxyz', '');
for $x in $alphabet
return concat('[', $x, ']')
<v:results v:warning="more than one node">
[] [a] [b] [c] [d] [e] [f] [g] [h] [i] [j] [k] [l] [m] [n] [o] [p] [q]
[r] [s] [t] [u] [v] [w] [x] [y] [z]
</v:results>
Why am I getting the empty string at the beginning of the sequence
returned from the above call to tokenize? Is this result expected?
Eric
