Trying to convert a CLOB to an XMLTYPE

Question

I'm trying to insert a xm ldocument stored in a CLOB into a XMLTYPE column registered to a schema.
I'm trying so use the function below to convert the CLOB to an XMLTYPEbut i keep getting a ORA-06553 Error: wrong number or arguments. Am i using the xmltype constructor properly?
create or replace function to_xmltype (clobcol CLOB)
return xmltype as
begin
return xmltype(clobcol,'http://localhost:8080/source/schemas/poSource/xsd/mySchema.xsd');
end;
insert into xml_table (xmldata) values (select to_xmltype(ct.clob_data) from clob_table ct );
Thanks for the help

Looks fine to me except that you should omit the values clause:
insert into xml_table (xmldata) select to_xmltype(ct.clob_data) from clob_table ct ;
