How to render $site_name without html tag? The $site_name variable get the name of the site wrapped in &lt;a&gt; tag but I want print only the value without html?

Is possible?

Thank you in advance.


  EDIT
  
  I'm using the strip_tags() function of php &lt;?php print strip_tags($site_name); ?&gt; but I don't know if is the best solution to solve the issue.
In a preprocess function you can get the title like this:

variable_get("site_name");
