Returns the part of $arg1
that follows the first occurrence of
$arg2
, taking collations into account.

If the value of $arg1
or $arg2
is the empty sequence, or
contains only ignorable collation units, it is interpreted as the zero-length
string.
If the value of $arg2
is the zero-length string, then the function returns
the value of $arg1
.
If the value of $arg1
does not contain a string that is equal to the value
of $arg2
, then the function returns the zero-length string.
The collation used by this function is determined according to the rules in .
The function returns the substring of the value of $arg1
that follows in
the value of $arg1
the first occurrence of a sequence of collation units
that provides a minimal match to the collation units of $arg2
according to the collation that is used.
Minimal match is defined in .
The collation used in these examples, http://example.com/CollationA
is a
collation in which both "-" and "*" are ignorable collation units.
"Ignorable collation unit" is equivalent to "ignorable collation element" in .
The expression fn:substring-after("tattoo", "tat")

"http://www.w3.org/2013/collation/UCA?lang=en;alternate=blanked;strength=primary")
returns "-fghi"
.
