You can do this shorter:

     function getPrefixFromURI($uri) {
         $prefixes = $this->dbModel->getParsedNamespaces();
         return @$prefixes[$uri];
     }

(Well, this returns null instead of "" if the prefix is not declared,  
but I think that's reasonable.)

You're right, it's a common need. The code above is short and self- 
explanatory, I think you can use it directly without a custom function.

Best,
Richard
