Update php with iuscommunity

I have been trying to upgrade the php on my server with the iuscommunity depository. I am having conflicts with remi, which is being tied by Plesk. Here is my effort to remove the offending file:

[root@d7w2-g8zq /]# rpm -qa | grep php-xml*
php-xml-5.4.13-1.el6.remi.x86_64
[root@d7w2-g8zq /]# rpm -e php-xml-5.4.13-1.el6.remi.x86_64
error: Failed dependencies:
php-xml is needed by (installed) psa-php5-configurator-1.7.0-cos6.build1205150820.19.x86_64
[root@d7w2-g8zq /]#

I don't understand...
