Return concatenation of string sequence.
fn:string-join(string* $stringSequence, string $separator) => string?
This function returns a possibly empty string that is created by
concatenating the members of $stringSequence using the value of
$separator. If the value of $separator is a string of
length zero, the members of $stringSequence are concatenated
without a separator.
| $stringSequence |
string value |
|---|---|
| $separator |
string value |
Some variants of simple string concatenation using different separators:
string-join(('do', 're', 'mi', 'fa', 'so', 'la', 'si'), "")
string-join(("veni", "vidi", "vici"), ", ")
string-join(("line 1", "line 2", "line3"), "
")
The first function call returns the string "doremifasolasi", the second returns "veni, vidi, vici", and the third call returns:
line 1 line 2 line 3
For all doctors with pagers whose numbers start with a "3" change the pager number by prepending "11-":
update for $a in input()//doctor
let $b := $a/@pager
where starts-with($b, "3")
do replace $b
with attribute pager { string-join(("11", $b), "-") }
