Hi,

> Weiss jemand einen Link, Rat, Hinweis?

ja, diese Funktion habe ich für meine Homepage geschrieben - aber leider
nicht kommentiert...

// formatiert fertigen HTML-Code

function format($page)
{
   $page = ereg_replace("\n", " ", $page);
   $page = ereg_replace("  ", " ", $page);
   $page = ereg_replace("<", "\n<", $page);
   $page = ereg_replace("}; ", "};\n", $page);
   $page = ereg_replace(">", ">\n", $page);
   $page = ereg_replace("\n ", "\n", $page);
   $page = ereg_replace("\n\n", "\n", $page);
   
   $lines = explode("\n", $page);
   $page = "";
   $spaces = "                                                                                            ";
   $offset = 0;
   $tab = 2;
   for ($x=0; $x<sizeof($lines); $x++) {
      $noffset = 0;
      $li = strtolower($lines[$x]);
      
      $npre = $pre;
      if ((substr($li,0,5) == "<pre>") || (substr($li,0,9) == "<textarea")) {
         $npre = $pre = TRUE;
         }
      if ((substr($li,0,6) == "</pre>") || (substr($li,0,11) == "</textarea>")) {

         }
