  HTTPService Requesting XML from FeedBurner Gets Parsed with XSL in IE Browser

  Andrei Ionescu | 10.09.08 | Permalink | 3 Comments

  toString() vs xmlToString()

  Andrei Ionescu | 29.01.08 | Permalink | Comment?

  I don’t know if you got in trouble when working with xmls but recently I found a bug (or a feature). Some differences when using toString() and/or xmlToString().

  x = "aaa";
  trace(X + ":" + x); // X:aaa
  var y:int = Y;
  y = 10;
  trace(Y +":" + y); //101:10
  var constantOrNot:XML = NotSoConstant;
  constantOrNot = …another [...]
