Subject: MDL-18974 - Remove phpxml library
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=3d6c36ff6e2fc799812733f7139450f03947ea25;p=moodle.git

MDL-18974 - Remove phpxml library

This embeded library was only used by the tag_youtube block, we now depend on
php5 and simplexml so these libraries can be used instead (as an aside Eloy
also the performance/memory usage to be far more efficient)
