Description

An internal table, carrier_tab, is filled with data from the database table SCARR and is transformed to XML using the simple transformation demo_st_table. The ST program is as follows:

<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
  <tt:root name="CARRIERS"/>
  <tt:template>
    <html>
          <body>
        <h2>Carriers:</h2>
        <table border="2">
          <tr>
            <td><b>Id</b></td>
            <td><b>Name</b></td>
            <td><b>Homepage</b></td>
          </tr>
          <tt:loop ref=".CARRIERS">
            <tr><td>
                <tt:value ref="$ref.carrid"/>
              </td>
              <td>
                <tt:value ref="$ref.carrname"/>
              </td>
              <td>
               <a><tt:attribute name="href" value-ref="$ref.url"/>
                  <tt:value ref="$ref.url"/></a>
              </td>
            </tr>
          </tt:loop>
        </table>
           </body>
    </html>
  </tt:template>
</tt:transform>

The transformation uses the ST statement tt:loop to serialize the other internal tables row by row. HTML tags are inserted into the XML document as literals.

The result of the transformation is displayed using the CL_ABAP_BROWSER class, first as an XML file, and then as a formatted HTML file.
