Error: php53-common conflicts with php-common when installing php53-xml on CentOS 5

I was trying to install php53-xml on CentOS 5.5. But instead I encountered the error instead. I', assuming  you have activated the webtatic repo and install the rest of the php 5.3 components like the How to yum install PHP 5.3 for CentOS 5

php53-common-5.3.3-21.el5.i386 from base has depsolving problems
  --> php53-common conflicts with php-common
Error: php53-common conflicts with php-common
 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

The issue of the problem is that the current PHP from webtatic is 5.3.27, but the one from yum php53-xml is 5.3.3 which is higher. To solve the issue, you have to use the php-xml from webtatic

# yum install  php-xml
