How can I fix a xquery resulting error ORA-19279: XPTY0004 - XQuery dynamic type mismatch: expected singleton sequence - got multi-item sequence

Question

Hello,
How can I improve the XQuery below in order to obtain a minimised return to escape from both errors ORA-19279 and ORA-01706?
XQUERY for $book in  fn:collection("oradb:/HR/TB_XML")//article let $cont := $book/bdy  where  $cont   [ora:contains(text(), "(near((The,power,Love),10, TRUE))") > 0] return $book
ERROR:
ORA-19279: XPTY0004 - XQuery dynamic type mismatch: expected singleton sequence
- got multi-item sequence
XQUERY for $book in  fn:collection("oradb:/HR/TB_XML")//article let $cont := $book/bdy  where  $cont   [ora:contains(., "(near((The,power,Love),10, TRUE))") > 0] return $book//bdy
/*ERROR:
ORA-01706: user function result value was too large

below query works for 1 iteration . but for multiple sets i am getting following error .
When you want to present repeating groups in relational format, you have to extract the sequence of items in the main XQuery expression.
Each item is then passed to the COLUMNS clause to be further shredded into columns.
This should work as expected :
select x.*
from abc t
   , xmltable(
       xmlnamespaces(
         default 'urn:swift:xsd:fin.970.2011'
       , 'urn:swift:xsd:mtmsg.2011' as "ns0"
     , '/ns0:FinMessage/ns0:Block4/Document/MT970/F61a/F61'
       passing t.col1
       columns F61ValueDate                Varchar(40) Path 'ValueDate'
             , DebitCreditMark             Varchar(40) Path 'DebitCreditMark'
             , Amount                      Varchar(40) Path 'Amount'
             , TransactionType             Varchar(40) Path 'TransactionType'
             , IdentificationCode          Varchar(40) Path 'IdentificationCode'                 
             , ReferenceForTheAccountOwner Varchar(40) Path 'ReferenceForTheAccountOwner'
             , SupplementaryDetails        Varchar(40) Path 'SupplementaryDetails'       
     ) x ;
