How to create an XML Oracle database schema

Question

Hello, I would like to generate an XML file that contains the schema of my Oracle database so that I can reference one file for column names and table names. I do not need any data from the tables, just the basic layout: e.g. table names, their respective column names.
Obviously, I would like the ability to generate this file each time we make changes to our DB, so its generation will be an ongoing process.
My question is, what is the best tool for this? Or the most widely accepted? Can anyone help with this?

To get database metadata as XML use Oracle Web RowSet.
//Import the oracle.jdbc.rowset package classes.
import oracle.jdbc.rowset.*;
//Import the RowSetMetaDataImpl class.
import javax.sql.rowset.RowSetMetaDataImpl;
//Create a OracleWebRowSet class.
OracleWebRowSet webRowSet=new OracleWebRowSet();
/*Set the datasource name to obtain a JDBC connection with the database. The datasource name is configured in the data-sources.xml file. */
webRowSet.setDataSourceName("jdbc/OracleDataSource");
//Set the SQL query command for the OracleWebRowSet class object.
webRowSet.setCommand(selectQuery);
selectQuery is a SQL command variable which is input from a JSP.
//Set the username and password to obtain a JDBC connection.
webRowSet.setUsername("OE");
webRowSet.setPassword("<password>");
//Set the read only, fetch size and max rows attributes of the OracleWebRowSet object.
webRowSet.setReadOnly(false);
webRowSet.setFetchSize(5);
webRowSet.setMaxRows(3);
//Run the SQL command specified in the setCommand() method.
webRowSet.execute();
/*A Web RowSet gets created consisting of the data retrieved from the database table with the SQL query.  Generate an XML document from the WebRowSet.*/
OutputStreamWriter output=new OutputStreamWriter( new
FileOutputStream(new File("c:/output/output.xml")));
webRowSet.writeXml(output);
