Suppose you have the following XML file. If I want to retrieve game1 moves, how would I do it using the simplest way in javascript?
<?xml version="1.0" encoding="utf-8" ?>
<playMoves>
<game id="game1" >
<move>
<pieceType>black</pieceType>
<pieceName>pawn</pieceName>
<moveFrom>82</moveFrom>
<moveTo>84</moveTo>
</move>
<move>
<pieceType>white</pieceType>
<pieceName>pawn</pieceName>
<moveFrom>87</moveFrom>
<moveTo>85</moveTo>
</move>
</game>
<game id = "game2" >
<move>
<pieceType>white</pieceType>
<pieceName>pawn</pieceName>
<moveFrom>87</moveFrom>
<moveTo>85</moveTo>
</move>
<move>
<pieceType>black</pieceType>
<pieceName>pawn</pieceName>
<moveFrom>82</moveFrom>
<moveTo>84</moveTo>
</move>
</game>
</playMoves>
