var str:String = "'''Test wiki data'''\n" +
"\n" +
"This is a test. This is ''only'' a test.\n" +
"Basic rules:\n" +
"* 3 single quote marks indicates '''bold'''.\n" +

return str;
}
Converts a wiki string to HTML text.
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 <b>foo</b>.
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 <i>foo</i>.
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 <p> HTML tag.
private function linesToParagraphs(input:String):String {
Strips out empty lines, which match /^
var pattern:RegExp = /^/gm;
var result:String = input.replace(pattern, "");
Adds <p> tags around all remaining lines. However, not those that begin with an asterisk, which are considered <li> items.
pattern = /^([^*].*)<p>$1</p>");
}
}
