如果 xml 文档包含架构,我在针对 xml 架构验证 xml 文件时遇到问题。xml 文件如下所示:
<?xml version="1.0"?>
<catalog xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:x="urn:book">
<!-- START OF SCHEMA -->
<xsd:schema targetNamespace="urn:book">
<xsd:element name="book">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="author" type="xsd:string"/>
<xsd:element name="title" type="xsd:string"/>
<xsd:element name="genre" type="xsd:string"/>
<xsd:element name="price" type="xsd:float"/>
<xsd:element name="publish_date" type="xsd:date"/>
<xsd:element name="description" type="xsd:string"/>
</xsd:sequence>
<xsd:attribute name="id" type="xsd:string"/>
</xsd:complexType>
</xsd:element>
</xsd:schema>
<!-- END OF SCHEMA -->
<x:book id="bk101">
<author>Gambardella, Matthew</author>
<title>XML Developer's Guide</title>
<genre>Computer</genre>
<price>44.95</price>
<publish_date>2000-10-01</publish_date>
<description>An in-depth look at creating applications with
XML.</description>
</x:book>
</catalog>
java代码看起来像:
// define the type of schema - we use W3C:
String schemaLang = "http://www.w3.org/2001/XMLSchema";
// get validation driver:
SchemaFactory factory = SchemaFactory.newInstance(schemaLang);
// create schema by reading it from an XSD file:
Schema schema = factory.newSchema(new StreamSource("..........."));
Validator validator = schema.newValidator();
// at last perform validation:
validator.validate(new StreamSource("myDoc.xml"));
我的问题是在这种情况下如何使用 SchemaFactory 对象?
我很感激任何帮助!
