Returns the value of $arg modified by replacing or removing individual
characters.
fn:translate( $arg as xs:string?,$mapString as xs:string,$transString as xs:stringxs:stringIf the value of $arg is the empty sequence, the function returns the
zero-length string.
Otherwise, the function returns a result string constructed by processing each character in the value of $arg, in order,
according to the following rules:
If the character does not appear in the value of $mapString then it
is added to the result string unchanged.
If the character first appears in the value of $mapString at some
position M, where the value of $transString is
M or more characters in length, then the character at position
M in $transString is added to the result string.
If the character first appears in the value of $mapString at some
position M, where the value of $transString is less than
M characters in length, then the character is omitted from the
result string.
The expression fn:translate("bar","abc","ABC") returns "BAr".
The expression fn:translate("--aaa--","abc-","ABC") returns "AAA".
The expression fn:translate("abcdabc", "abc", "AB") returns "ABdAB".
If $mapString is the zero-length string then the function returns
$arg unchanged.
If a character occurs more than once in $mapString, then the first
occurrence determines the action taken.
If $transString is longer than $mapString, the excess
characters are ignored.
