将org.w3c.dom.Node转换为Document [英] Convert org.w3c.dom.Node into Document

问题描述

我从一个文档获得节点。我想把节点并将其转换为新的文档的根节点。

I have a Node from one Document. I want to take that Node and turn it into the root node of a new Document.

我能想到的唯一方法如下：

Only way I can think of is the following:

Node node = someChildNodeFromDifferentDocument;

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);

DocumentBuilder builder = factory.newDocumentBuilder();

Document newDocument = builder.newDocument();
newDocument.importNode(node);
newDocument.appendChild(node);

这样可行，但我觉得这很烦人。有没有更简洁/更直接的方式我没有看到，或者我只是必须这样做？

This works, but I feel it is rather annoyingly verbose. Is there a less verbose/more direct way I'm not seeing, or do I just have to do it this way?

推荐答案

代码对我不起作用 - 但是有一些变化相关问题我可以按照以下方式使用它：

The code did not work for me - but with some changes from this related question I could get it to work as follows:

Node node = someChildNodeFromDifferentDocument;
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
DocumentBuilder builder = factory.newDocumentBuilder();
Document newDocument = builder.newDocument();
Node importedNode = newDocument.importNode(node, true);
newDocument.appendChild(importedNode);
