根据xml架构验证xml文件 [英] validate xml file against xml schema

问题描述

这是关于针对XML模式验证XML文件（例如：marshalledfile.xml）（例如：schemafile.xsd）。我们使用jaxb将java对象编组到一个xml文件中。

this is about validating a XML file (eg: marshalledfile.xml) against a XML schema (eg: schemafile.xsd). we are using jaxb to marshall java objects into into a xml file.

1. 最好的方法是什么？

推荐答案

您可以直接在Marshaller中设置Schema。首先，您需要创建一个Schema实例（javax.xml.validation包）：

You can set the Schema directly in the Marshaller. First, you need to create a Schema instance (javax.xml.validation package):

SchemaFactory factory = SchemaFactory.newInstance(
            XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = factory.newSchema(new StreamSource(new File("schema1.xsd")));

现在您已拥有Schema，只需将Marshaller中的属性设置为
即可验证生成的XML：

Now that you have the Schema, just set the property in the Marshaller to validate the generated XML:

MovieLibrary library = ...; // <-- your JAXB-annotated tree

JAXBContext ctx = JAXBContext.newInstance(MovieLibrary.class);
Marshaller marshaller = ctx.createMarshaller();
marshaller.setSchema(schema);
marshaller.marshal(new JAXBElement<MovieLibrary>(new QName("movieLibrary"), 
                                                    MovieLibrary.class, library),
                   new FileOutputStream("/tmp/library.xml"));
