java - 如何将数组字节转换为org.w3c.dom.Document

我有一个文档(org.w3c.dom.Document)，我将此文档转换为字节数组:

private byte[] obtenerBytesDeDocument(Document documentoXml) throws Exception {
    Source source = new DOMSource( documentoXml );
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    Result result = new StreamResult(out);
    TransformerFactory factory = TransformerFactory.newInstance();
    Transformer transformer = factory.newTransformer();
    transformer.transform(source, result);
    byte[] butesXml =  out.toByteArray();
    return butesXml;
}

我需要将字节数组新转换为文档:

private Document obtenerDocumentDeByte(byte[] documentoXml) throws Exception {
        ...
}

任何想法？

谢谢!!!

最佳答案

以下应该工作。

private Document obtenerDocumentDeByte(byte[] documentoXml) throws Exception {
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    factory.setNamespaceAware(true);
    DocumentBuilder builder = factory.newDocumentBuilder();
    return builder.parse(new ByteArrayInputStream(documentoXml));
}
