* but a bunch of potentially expensive regular expressions. You should use it only if
* you control the length of the excerpt too. Otherwise you could run into memory issues
* or some obscure bugs." <http://wordpress.stackexchange.com/a/89169/8521>

* For more reasons why to not use regular expressions on markup, see http://stackoverflow.com/a/1732454/93579
