Using MODx caching for own purposes

Here’s the situation:
Within MODx, I’m retrieving a file list from a remote server using SOAP.
I want the retrieved data (a simple array) to be cached. My initial plan was to use the PEAR::Cache_Lite class, but this throws a MODx parse error in my face sad

(This has to do with a failing @fopen on a missed cache event, see also the topics http://modxcms.com/forums/index.php/topic,4340.0.html and http://modxcms.com/forums/index.php/topic,4306.0.html)

I really would like to use the PEAR::Cache_Lite classes, but as an alternative, would it be possible to use the MODx caching system to cache your own data (an array in my case).

I guess you could create your array within the documentObject, say
$modx->documentObject[’myarray’] = array(’A’ => 1, ’B’ => 2);
Since the documentObject gets cached and rebuild from cache your data would be restored, too. Not tested at all. ;-)
See document.parser.class.inc.php for details.

Thanks! This works like a charm!
My code:

if (!isset($modx->documentObject["albumcache_".$directory])) {
    // This include fills $pic_list by using SOAP
    include APP_ROOT."include/getRemoteAlbum.php";
    $modx->documentObject["albumcache_".$directory]=$pic_list;
} else {
    $pic_list=$modx->documentObject["albumcache_".$directory];
}

// This include file show webalbum by using the contents of $pic_list
include_once APP_ROOT."webAlbum.php";

return $return_value;
