The task is to execute functions stored in a database, preferably xml. For example a function containing system.out.println("a"); is stored in a file code.xml and has been extracted as a string, how can a program be made so as to execute said code ?

Winning criteria : Efficient and fast code (as the executed functions may themseleves be long too)

How are you going to check the fastest code? –  ProgramFOX Jan 11 at 16:37
    
Sorry if it seems amateur, but I was hoping for execution time of codes ! –  rijul gupta Jan 11 at 16:40
    
And how are you going to check the execution time? –  ProgramFOX Jan 11 at 16:49
    
I am used to using netbeans, it has a feature of showing execution time. I suppose that should do the job. –  rijul gupta Jan 11 at 16:56
    
But what if someone posts a code in a language that Netbeans doesn't support? –  ProgramFOX Jan 11 at 17:03

Polyglot (Ruby, JavaScript, Python, PHP, Perl)

Assuming code is stored in the $c variable: 

eval($c);

Looks like I posted it 30s late :P –  Vereos Jan 11 at 16:40
    
I have a small query, all over the Internet eval is ridiculed as writing such codes brings up problems of security and code repairs, is this really a reliable way ? –  rijul gupta Jan 11 at 16:44

You didn't ask for reliable, you asked for efficient and fast. –  Paul R Jan 11 at 17:08
    
I know I did not, it was more like an addendum to the existing query. –  rijul gupta Jan 11 at 18:08

PHP 5

$xml = simplexml_load_file("code.xml");
$myFun = (string) $xml->Function['value']; //Example path as no specs were given.
eval $myFun;
