substring-after( )

Synopsis

                     string substring-after(string s1, string s2)

The substring-after() function returns the substring of s1 that follows the first occurrence of s2 in s1, or it returns the empty string, if s1 does not contain s2. For example, substring-after('Charming cat', 'harm') returns "ing cat“. The test is case-sensitive. As usual, nonstring objects may be passed to this function, in which case they’re automatically converted to strings, as if by the string( ) function.
