Retriving the XMLData from a table of XMLtype

Question

Hi,
I am Creating a table of xmltype and inserting xml into the table.
1. create table test_tab of xmltype xmlschema "/public/config.xsd" element "Config" ;
2. insert into test_tab values('<Config
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="/public/config.xsd">
<ApsConfig>
<TcpInterfaceConfig>
<Mode>CONNECT</Mode>
<Port>28496</Port>
</TcpInterfaceConfig>
</ApsConfig>
</Config>');
How to retrieve the above inserted row into a new XML file?
If i used the dbms_xmlgen() to get the xml, its not showing properly.
Please help me.
Thanks ahead.....

From Oracle's documentation
The DBMS_XMLGEN package converts the results of a SQL query to a canonical XML formatSince your data is already XML, there is no need to use DBMS_XMLGEN (unless you are doing something more complex not mentioned in your post). Just use a simple
select * from test_tab;
to see your data.
Example:
Connected to Oracle Database 11g Enterprise Edition Release 11.1.0.6.0
SQL> create table test_tab of xmltype;  -- shortened as don't have your schema
Table created
SQL>
SQL> insert into test_tab values('<Config
  2  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  3  xsi:noNamespaceSchemaLocation="/public/config.xsd">
  4  <ApsConfig>
  5  <TcpInterfaceConfig>
  6  <Mode>CONNECT</Mode>
  7  <Port>28496</Port>
  8  </TcpInterfaceConfig>
  9  </ApsConfig>
10  </Config>');
1 row inserted
SQL> select * from test_tab;
SYS_NC_ROWINFO$
<Config
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceS
SQL> set long 1000  -- Doing for display purposes only
SQL> select * from test_tab;
SYS_NC_ROWINFO$
<Config
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="/public/config.xsd">
<ApsConfig>
<TcpInterfaceConfig>
<Mode>CONNECT</Mode>
<Port>28496</Port>
</TcpInterfaceConfig>
</ApsConfig>
</Config>
