我有下面的XML文件:XML驗證:CVC-elt.1:找不到元素的聲明 'XXX'
<?xml version="1.0"?>
<!DOCTYPE library SYSTEM "library.dtd">
<library
xmlns="http://example.com/a"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://example.com library.xsd"
name=".NET Developer's Library">
<book>
<category>computerss</category>
<title>Programming Microsoft .NET</title>
<author>Jeff Prosise</author>
<isbn>0-7356-1376-1</isbn>
</book>
<book>
<category>computer</category>
<title>Microsoft .NET for Programmers</title>
<author>Fergal Grimes</author>
<isbn>1-930110-19-7</isbn>
</book>
</library>
而且Java代碼:
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
SchemaFactory sf = SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema");
docBuilderFactory.setSchema(sf.newSchema(new File("library.xsd")));
docBuilderFactory.setNamespaceAware(true);
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
docBuilder.parse(new FileInputStream("data.xml"));
它產生以下錯誤:
[Error] :7:33: cvc-elt.1: Cannot find the declaration of element 'library'.
如果我刪除在X XSD聲明ML文件一切工作正常...
任何內部高度讚賞。謝謝。
這裏是架構:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="library">
<xs:complexType>
<xs:sequence>
<xs:element ref="book" maxOccurs="unbounded"/>
</xs:sequence>
<xs:attribute name="name" type="xs:string" use="optional"/>
</xs:complexType>
</xs:element>
<xs:element name="book">
<xs:complexType>
<xs:sequence>
<xs:element ref="category"/>
<xs:element ref="title"/>
<xs:element ref="author"/>
<xs:element ref="isbn"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="category">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:enumeration value="computer" />
<xs:enumeration value="poetry" />
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="title" type="xs:string"/>
<xs:element name="author" type="xs:string"/>
<xs:element name="isbn" type="xs:string"/>
</xs:schema>
