ID BOOK               AUTHOR
1  PHP Undercover     Wiwit Siswoutomo
2  PHP Webservices    Ilmia

Be transformed into recordset element:

<recordset rowCount="2" fieldNames="ID,BOOK,AUTHOR">
  <field name="ID">
    <number>1</number>
    <number>2</number>
  </field>
  <field name="BOOK">
    <string>PHP Undercover</string>
    <string>PHP Webservices</string>
  </field>
  <field name="AUTHOR">
    <string>Wiwit Siswoutomo</string>
    <string>Ilmia</string>
  </field>
</recordset>
