  child = xml.child.map {
    case elem: Elem if elem.label == "tagToUpdate" =>
      elem.copy(child = elem.child.map {
        case text: Text => Text("Updated Value")
        case other => other
      })
    case other => other
  }

// 删除节点
val deletedXml = xml.copy(
  child = xml.child.filterNot {
    case elem: Elem if elem.label == "tagToDelete" => true
    case _ => false
