XQSEQUENCEFROMXMLTYPE -- ora-00932

Question

I was trying to view the trace file output of a session trace. Used TKPROF to read the trace file for me. This is a part of the file I found:
SELECT XMLELEMENT("ISA", XMLAGG(T.COLUMN_VALUE))
FROM
XMLTABLE('/ISA/node()[ora:matches(name(),"ISA")]' PASSING :B1 ) T

error during execute of EXPLAIN PLAN statement
ORA-00932: inconsistent datatypes: expected - got CHAR
parse error offset: 184I am guessing this has something to do with the XQuery within the sql statement I had in there.
Right after that , I had this piece of information:
begin :1 := sys.dbms_xqueryint.getXQueryX(:2); end;

Anyway, I would like to know what happened here to give this ora-00932 error?
Thank you for your consideration,
Rahul.

Invalid Month error in PL/SQL
¿what is fec_alta? I suppose is a type date
Modify
fmodif:=TO_DATE(fec_alta||' '||hor_alta,'DD/MM/YYYY HH24:MI:ss');
For
fmodif:=TO_DATE( to_char(fec_alta, 'DD/MM/YYYY') ||' '||hor_alta,'DD/MM/YYYY HH24:MI:ss');
