Data Model Requirements

The XML data used as input to the report must wrap the HTML portion of the data in a CDATA section.

You can retrieve data stored in the form of XHTML documents stored in a database CLOB column and render the markup in the generated report.

RTF Template Requirements

To render the HTML in your report, use the following tag in the RTF template.

The tag is:

<?html2fo: elementname?>

where elementname is the XML element name that contains the HTML data.

Example

This example uses the mentioned XML data with embedded HTML data.

<?xml version="1.0" encoding="UTF-8"?>
<RTECODE>
<![CDATA[
<p><font style="font-style: italic; font-weight: bold;" size="3">
<a href="http://www.oracle.com">oracle</a></font> </p>
<p><font size="6"><a href="http://docs.oracle.com/">Oracle Documentation</a>
</font></p>
]]>
</RTECODE>

To render this sample as formatted HTML a report, enter the following in your RTF template:

<?html2fo: RTECODE?>
