Source Code framework/web/renderers/CPradoViewRenderer.php
CPradoViewRenderer implements a view renderer that allows users to use a template syntax similar to PRADO templates.

To use CPradoViewRenderer, configure it as an application component named "viewRenderer" in the application configuration:

CPradoViewRenderer allows you to write view files with the following syntax:
// PHP tags:
<%= expression %>
// <?php echo expression ?>
<% statement %>
// &lt;?php statement ?&gt;</li>

// component tags:
&lt;com:WigetClass name1="value1" name2='value2' name3={value3} &gt;
// &lt;?php $this->beginWidget('WigetClass',
// array('name1'=>"value1", 'name2'=>'value2', 'name3'=>value3)); ?&gt;
&lt;/com:WigetClass &gt;
// &lt;?php $this->endWidget('WigetClass'); ?&gt;
&lt;com:WigetClass name1="value1" name2='value2' name3={value3} /&gt;
// &lt;?php $this->widget('WigetClass',
// array('name1'=>"value1", 'name2'=>'value2', 'name3'=>value3)); ?&gt;

// cache tags:
&lt;cache:fragmentID name1="value1" name2='value2' name3={value3} &gt;
// &lt;?php if($this->beginCache('fragmentID',
// array('name1'=>"value1", 'name2'=>'value2', 'name3'=>value3))): ?&gt;
&lt;/cache:fragmentID &gt;
// &lt;?php $this->endCache('fragmentID'); endif; ?&gt;

// clip tags:
&lt;clip:clipID &gt;
// &lt;?php $this->beginClip('clipID'); ?&gt;
&lt;/clip:clipID &gt;
// &lt;?php $this->endClip('clipID'); ?&gt;

// comment tags:
&lt;!--- comments ---&gt;
// the whole tag will be stripped off
