use the function apex_string.split to split clobs. (available since APEX 19.2)
select s.column_value from clob_tab, table(apex_string.split(clob_column,'class:abcd'||chr(10)||'}')) s;

Assuming you are on 12C or higher:

with sample as (
                select '{
adam smith
class:abcd
}
{
xxxyyyy
class:abcd
}
{
zzzz
class:abcd
}' data from dual
)
select  rownum,
        r
  from  sample,
        lateral(
                select  regexp_substr(data,'{[^}]*}',1,level) r
                  from  dual
                  connect by level <= regexp_count(data,'{')
               )
/

    ROWNUM R
---------- --------------------
         1 {
           adam smith
           class:abcd
           }

         2 {
           xxxyyyy
           class:abcd
           }

         3 {
           zzzz
           class:abcd
           }

And if performance is a factor you can change REGEXP_SUBSTR with SUBSTR + INSTR and REGEXP_COUNT with LENGTH + REPLACE.
