"WRONG_DOCUMENT_ERR: A node is used in a different document than the one that created it" 尽管我正在另一个节点中导入，但抛出了异常

Question

我正在尝试将节点附加到 xml 文件中的正文元素，如下所示：

  Document document2 = db.newDocument();
  Node node = document2.importNode(document.getFirstChild(), true);
  envelope.getBody().addBodyElement(QName.valueOf("com:createLicense")).appendChild(node);

我遇到了这个异常：

org.w3c.dom.DOMException: WRONG_DOCUMENT_ERR: A node is used in a different document than the one that created it.

任何suggestions/solutions？

问题是我正在处理三个文档。

解决方案如下：

Document document = db.newDocument();
jaxbMarshaller.marshal(jaxbElement, document);
DocumentFragment docFrag = document.createDocumentFragment();
Element rootElement = document.getDocumentElement();
docFrag.appendChild(rootElement);
Document ownerDoc = soapBody.getOwnerDocument();
Node replacingNode = ownerDoc.importNode(docFrag, true);

envelope.getBody().addBodyElement(QName.valueOf("com:createLicense")).appendChild(node);
