Magento custom cache clear by regex

Question

Is it possible in Magento to allow for cache to be cleared in a custom code by using regular expression to target cache tags?

The scenario I have is I am know of a list of cache tags I will be cleaning but they will each have a different suffix on them.

Answer 1

If you setup your tags and keys correctly in your custom module, calling

Mage::app()->cleanCache();

Should do what you need, without the ugly regex.
