[haXe] XML nodeType enum

[Zjnue Brzavi]

Hi Keith,

I played with some Xml routines a while ago. I managed with Std.string
as you mentioned. Just checked and it still compiles fine with haXe
1.08. Here is a snippet:

static function stripNodes( x : Xml ) : Xml {
  var nodeVal;
  for ( i in x ) {
    switch ( Std.string( i.nodeType ) ) {
      case Std.string( Xml.PCData ) :
        nodeVal = stripWhite( i.nodeValue );
        if ( nodeVal == "" ) {
          x.removeChild( i );
        } else {
          i.nodeValue = nodeVal;
        }
      case Std.string( Xml.Element ) :
        i = stripNodes( i );
      default :
        x.removeChild( i );
    }
  }
  return x;
}

Hope it helps,

Zjnue
