Precautions needed while looping through publishing site subsites

In publishing site you have the additional sites like Document center, News,Reports,Search and sites. While retrieving data from subsites you should stop looping of these subsites like this.

spweb currentweb=spcontext.current.web;
foreach(spweb objSite in currentweb.GetSubwebsForCurrentUser())
{
     if (objSite.Title != "Document Center" && objSite.Title != "News" && objSite.Title != "Reports" && objSite.Title != "Search" && objSite.Title != "Sites")
     {
         //Write your code here.
     }

}
