它在线程“main”org.w3c.dom.DOMException中抛出异常:WRONG_DOCUMENT_ERR:节点用于与创建它的文档不同的文档中。 at org.apache.xerces.dom.ParentNode.internalInsertBefore(Unknown Source) at org.apache.xerces.dom.ParentNode.insertBefore(Unknown Source) 在org.apache.xerces.dom.NodeImpl.appendChild(未知来源)

Document.importNode
不会更改其调用的节点。你应该改变这一行:
document.importNode(node,true);
到
node = document.importNode(node,true);
或者,使用其他变量:
Node importedNode = document.importNode(node, true);
parent.appendChild(importedNode);
