Built-in XML functions

I am trying to use built-in XML functions, but I’m getting an %s: invalid identifier error. Selects works fine without the XML functions.

Any ideas where is the mistake?

select id,full_name from users where id in(
with sample_data as
(
 (select pm_id 
 from pm  where p_id=30369)
)
select cast(t.column_value.extract('//text()') as varchar2(40)) val
  from sample_data,
  table( xmlsequence( xmltype(
    '<x><x>' || replace(pm_id, '#@#', '</x><x>') || '</x></x>'
  ).extract('//x/*'))) t)
