EXECUTE IMEDIATE with a result set based DDL command?

Question

How can I get the exec immed to work in this manner?
execute immediate 'select ' DROP INDEX '' || INDEX_NAME || '' from dba_indexes where index_name = ''%STRING%'';
I want to retrieve the list of INDEXES from the dba_indexes where the name is like a certain STRING and drop them.
Is there a better way to do this all in a PL/SQL session/command?
Thanks for any help I can get,
Miller

I resolved issue using a spool file and executing that like such:
/* This will remove all objects created by the migration objects */
set heading off
set feedback off
spool c:\temp\cleanup.txt
select 'DROP INDEX ' || INDEX_NAME || ' ; ' from dba_indexes where index_name like '%99%' and index_type = 'NORMAL' and index_name not like '%SYS%';
select 'DROP TABLE ' || TABLE_NAME || ' ;'  from dba_tables where table_name like 'DYNEGY_%' and table_name <> 'DYNEGY_SCRIPT_STATISTICS';
spool off
@c:\temp\cleanup.txt
