<div class="[[+myclass]]">
[[+myContent]]

[[!anotherSnippet?properties=`xxx`]]
</div>

<?php
/* All database treatment has been done */
$data = $modx->mycomponent->getChunk('chunk', $arr);

// This is where i want to parse my Chunk for tags that are not placeholders
// And then send the processed chunk to the browser

$response['success'] = true;
$response['data'] = $data;
return $this->modx->toJSON($response);

<?php

/* get the max iterations tags are processed before processing is terminated */

/* parse all cacheable tags first */

/* parse all non-cacheable and remove unprocessed tags */
