如何將InputStream轉換爲Source？

Question

我想驗證xml文檔使用xsd模式文件存儲在我的設備上。 這裏是我的示例代碼：

SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI); 

// schema file on my device 
InputStream isSchema = context.getResources().openRawResource(xsd_file); 
// InputStream => Source conversion 
Source schemaSource = ???? 
Schema schema = factory.newSchema(schemaSource); 

Validator validator = schema.newValidator(); 
validator.validate(new DOMSource(document)); 

問：我如何轉換的InputStream成的SchemaFactory :: newSchema方法所需的源？

Answer 1

你不轉換，你包裝它。

Source schemaSource = new StreamSource(isSchema);
