Description

Note

This directive is still working, but deprecated. You may want to read about user-defined directive calls to see the replacement.

Captures the output generated inside its body (i.e. between its start-tag and end-tag), and let the given transform modify it before it is written to the final output.

Example:

<p>A very simple HTML file:
<pre>
<transform html_escape>
<html>
  <body>
    <p>Hello word!
  </body>
</html>
</transform>
</pre>

the output will be:

<p>A very simple HTML file:
<pre>
&lt;html&gt;
  &lt;body&gt;
    &lt;p&gt;Hello word!
  &lt;/body&gt;
&lt;/html&gt;
</pre>

Some transforms may take parameters. The name and meaning of parameters depends on the transform in question. For example here we give a parameter called ``var'':

<#-- This transform stores the output in the variable x,
     rather than sending it to the output -->
<transform capture_output var="x">
some test
</transform>

It is the task of the programmers to put the necessary transforms into the data-model. For the name and usage of accessible transforms ask the programmers. Initially there is a shared variable for most transforms in the freemarker.template.utility package. For more information see: Programmer's Guide/The Configuration/Shared variables
