Element attributes do not get created, and to create them apply an XSLT to the XML document that was created from the database table with the OracleXMLQuery class.

The procedure to create an XML document with elements and element attributes is discussed in this section. Import the OracleXMLQuery class and create an OracleXMLQuery class object:

OracleXMLQuery query = new OracleXMLQuery(conn, "SELECT CATALOGID, JOURNAL_TITLE, PUBLISHER, EDITION, ARTICLE_SECTION, TITLE, AUTHOR FROM JOURNAL");

Variable conn is the JDBC connection used to query the database. The SELECT SQL statement specifies the query to select data from the database table, JOURNAL. Apply an XSLT to the OracleXMLQuery...
