一种不好的删除XML空白节点和注释节点的方法

public static void deleteNoteAndBlank(Node node) {if (node.getNodeType() == TEXT_TYPE || node.getNodeType() == NOTE_TYPE) {return;}ArrayList<Node> deleteNodes = new ArrayList<Node>();for (int i = 0; i < node.getChildNodes().getLength(); i++) {Node childNode =  node.getChildNodes().item(i);//递归deleteNoteAndBlank(childNode);//不能一个一个删除,否则后续节点会计算错误....if ((childNode.getNodeType() == TEXT_TYPE && childNode.getNodeValue().length() == 2) || childNode.getNodeType() == NOTE_TYPE) {deleteNodes.add(childNode);}}for (int i = 0; i < deleteNodes.size(); i++) {node.removeChild(deleteNodes.get(i));}}
