如何将数组字节转换为org.w3c.dom.Document

我有一个Document（org.w3c.dom.Document），我把这个文件转换为byte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; } 

我需要将字节数组转换为新文档：

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

任何想法？

Thansks！

以下应该有效。

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