Call to undefined function xml_parser_create()

Question

Could you please help me in resolving this conflict. I am tryin to run a xml_parse_create.
My server configurations:
[root@server ~]# php -v
PHP 7.0.22 (cli) (built: Aug 7 2017 16:18:27) ( NTS )

[root@server ~]# nginx -v
nginx version: nginx/1.10.2

OS: CentOS 7.3.1611 (Core)

Details of my YUM installation:

[root@server ~]# yum list installed | grep php
php70u-cli.x86_64                       7.0.22-2.ius.centos7           @ius     
php70u-common.x86_64                    7.0.22-2.ius.centos7           @ius

php70u-pdo.x86_64                       7.0.22-2.ius.centos7           @ius  

Here is the details of the investigation:

I tried executing following code in test.php:

<?php
$xml_parser = xml_parser_create("");
print $xml_parser;<br>
?>

[root@server ~]# php /tmp/test.php
PHP Fatal error: Uncaught Error: Call to undefined function

[root@server ~]# sudo yum install php-xml

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

Under ubuntu you can do the same as @Tarun pointed

apt-get install php-xml
apt-get search php |grep xml
