Likely problem is that you tried to insert node to the target document without importing it. Importing node to target document is done via Document.importNode. Code is roughly as follows, of course exact location in target document should be changed specific to you application:

可能的问题是您尝试将节点插入目标文档而不导入它。将节点导入目标文档是通过Document.importNode完成的。代码大致如下,当然,目标文档中的确切位置应根据您的应用程序进行更改:

    NodeList list ...
    for(int i=0; i < list.getLength(); i++){
        Node nodeToImport = list.item(i);
        Node importedNode = targetDocument.importNode(nodeToImport, true);
        targetDocument.getDocumentElement().appendChild(importedNode);
    }
