HTML entities

[fbraem]

Just a quick question before I start developing my own solution while it is maybe already part of POCO (A donkey does not bump into the same stone twice, they say in Dutch).

Is there a way to encode &, <, >, ... for HTML?

Not yet. I use following function, which I plan to make a static member of HTTPRequestHandler some day...

Code: Select all

   std::string htmlize(const std::string& str)
   {
      std::string::const_iterator it(str.begin());
      std::string::const_iterator end(str.end());
      std::string html;
      for (; it != end; ++it)
      {
         switch (*it)
         {
         case '<': html += "&lt;"; break;
         case '>': html += "&gt;"; break;
         case '"': html += "&quot;"; break;
         case '&': html += "&amp;"; break;
         default:  html += *it; break;
         }
      }
      return html;
   }

why not declare the iterator in the for(), and no var for the end() ==> that way reduction of the scope of the variable ?
The fact that the end 'could' be calculated at every loop check might even be optimized out by the compiler, and on the other hand is probably not a bottleneck on its own.
The scope reduction make the code easier to grasp/read.

Just my 2 cents

Or an std::transform with a functor ?

Of C++11 : auto / cbegin() / cend() , I know : too early for this.
