nextElementSibling property

Implementation

XmlElement? get nextElementSibling {
  final siblings = this.siblings;
  for (var i = 0; i < siblings.length - 1; i++) {
    if (identical(siblings[i], this)) {
      for (var j = i + 1; j < siblings.length; j++) {
        final candidate = siblings[j];
        if (candidate is XmlElement) {
          return candidate;
        }
      }
      return null;
    }
  }
  return null;
}
