XML SQL Urgent Query

Question

I am trying to generate an XML file from a database table. I loaded the xmlparser for java into the database and executed the catxsu.sql script as indicated in the documentation. All the relevant files are in the Oracle Home. There is a sample script in the documentation and I have tried to run it from SQLplus. I set the serveroutput to on so I could see the results. The following shows the code I used and the errors. Any suggestions as to what the problem is? Thanks
SQL> declare
2 queryCtx DBMS_XMLquery.ctxType;
3 result CLOB;
4 begin
5 queryCtx := DBMS_XMLquery.newContext('select * from emp_LOH');
6 result := DBMS_XMLQuery.getXML(queryCtx);
7 PrintClobOut(result);
8 DBMS_XMLQuery.closeContext(queryCtx);
9 end;
10 /
PrintClobOut(result);
ERROR at line 7:
ORA-06550: line 7, column 1:
PLS-00201: identifier 'PRINTCLOBOUT' must be declared
ORA-06550: line 7, column 1:
PL/SQL: Statement ignored

Answer 1

I created the PrintClobOut procedure and now I get the following errors when I execute the code:
SQL> declare
2 queryCtx DBMS_XMLquery.ctxType;

5 queryCtx := DBMS_XMLquery.newContext('select * from emp_LOH');
6 result := DBMS_XMLQuery.getXML(queryCtx);
7 PrintClobOut(result);
8 DBMS_XMLQuery.closeContext(queryCtx);
9 end;
