Blank page at template manager, in T3 blank template

Dear Admin,


I am new in T3 & Joomla, i got a blank page at Template Manager after I install the T3 blank template J3.2.

I tried to use other JA template and it happened the same.

So I turned the error reporting on and notice this message:
Fatal error: Call to undefined function dom_import_simplexml() in /home/exposedc/public_html/libraries/joomla/form/form.php on line 887

My Apache version is 2.2.24, PHP version 5.3.27 and MySQL version 5.1.72-cll

Thanks
