如何为InputStream转换成源？ [英] How to convert InputStream into Source?

问题描述

我想用我的存储设备上的 XSD 的模式文件来验证的 XML 的文档。
这里是我的例子code：

I want to validate xml document using xsd schema file stored on my device. Here is my example code:

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));

问：如何转换的InputStream成的SchemaFactory :: newSchema方法所需来源？

Question: How can I convert InputStream into Source required by SchemaFactory::newSchema method ?

推荐答案

您没有转换，你把它包起来。

You don't convert, you wrap it.

Source schemaSource = new StreamSource(isSchema);
