Hi Jim,
I was able to get string-join() to work, here's the code:
fn:string-join(
let $string := "ABC"
let $data := (1, 3, 1, 2)
for $i in $data
return fn:substring($string, $i, 1)
, "")
Hope that works for you.

Hi,
I have a sequence of integers that I iterate through to get a numeric
equivalent from a string based on the corresponding position.
e.g.
let $string := “ABC”
let $data := (“1”, “3”, “1”, “2”)
for $i in $data
return (
(: get the substring that is 1 character long from $string at
position $i :)
fn:substring($string, $i, 1)
)
I’m using this to build part of a URL where no spaces are allowed.
So what I would like is the following string:
“ACAB”
But what I’m getting is a sequence
A C A B
How can I cast a sequence to a string?
If I try string-join or similar I get an “invalid coercion” error.
Thanks in advance for what I’m sure is a simple thing to solve,
Jim
