                  public function parseWikiString (wikiString:String):String {
                          var result:String = parseBold(wikiString);
                          result = parseItalic(result);
                          result = linesToParagraphs(result);
                          result = parseBullets(result);
                          return result;
                  }

Replaces a bold pattern in a wiki string with the HTML equivalent. For example '''foo''' becomes foo.


  
                  private function parseBold(input:String):String {
                          var pattern:RegExp = /'''(.*?)'''/g;
                          return input.replace(pattern, "<b>$1</b>");
                  }

Replaces an italic pattern in a wiki string with the HTML equivalent. For example ''foo'' becomes foo.


  
                  private function parseItalic(input:String):String {
                          var pattern:RegExp = /''(.*?)''/g;
                          return input.replace(pattern, "<i>$1</i>");
                  }

Replaces a bold pattern in a wiki string with the HTML equivalent. For example the following line: * foo Becomes this: <li>foo</li>


  
                  private function parseBullets(input:String):String {
                          var pattern:RegExp = /^\*(.*)/gm;
                          return input.replace(pattern, "<li>$1</li>");
                  }

Replaces a newline in a wiki string with the  HTML tag.


  
                  private function linesToParagraphs(input:String):String {

Strips out empty lines, which match /^ $/gm$


  
                          var pattern:RegExp = /^/gm;
                          var result:String = input.replace(pattern, "");

Adds  tags around all remaining lines. However, not those that begin with an asterisk, which are considered <li> items.


  
                          pattern = /^([^*].*) $/gm;
                          return result.replace(pattern, "$ <p>$1</p>");
                  }          
          }
  }
