Question

我有以下XML内容：

<?xml version="1.0" encoding="UTF-8"?>

我想使用以下XML Schema验证它：

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"
           targetNamespace="http://bioontology.org/bioportal/classBeanSchema#"
           xmlns:c="http://bioontology.org/bioportal/classBeanSchema#">
    <xs:element name="success">
        <xs:complexType>
            <xs:sequence>
                <xs:element ref="c:accessedResource"/>
                <xs:element ref="c:accessDate"/>
                <xs:element ref="c:data"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
    <xs:element name="accessedResource" type="xs:string"/>
    <xs:element name="accessDate" type="xs:string"/>

    <xs:element name="data">
        <xs:complexType>
            <xs:all>

                <xs:element ref="c:classBean" minOccurs="0" maxOccurs="1"/>
            </xs:all>
        </xs:complexType>
    </xs:element>
    <xs:element name="classBean">
        <xs:complexType>
            <xs:choice minOccurs="0" maxOccurs="unbounded">
                <xs:element ref="c:fullId" maxOccurs="1" minOccurs="0"/>
                <xs:element ref="c:id" maxOccurs="1" minOccurs="0"/>
                <xs:element ref="c:label" maxOccurs="1" minOccurs="0"/>
                <xs:element ref="c:relations" maxOccurs="1" minOccurs="0"/>
                <xs:element name="type" type="xs:string" maxOccurs="1" minOccurs="0"/>
            </xs:choice>
        </xs:complexType>
    </xs:element>

    <xs:element name="fullId" type="xs:string"/>
    <xs:element name="id" type="xs:string"/>
    <xs:element name="label" type="xs:string"/>

    <xs:element name="relations">
        <xs:complexType>
            <xs:sequence>
                <xs:element minOccurs="0" maxOccurs="unbounded" ref="c:entry"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

    <xs:element name="entry">
        <xs:complexType>
            <xs:sequence>
                <xs:choice minOccurs="0" maxOccurs="unbounded">
                    <xs:element name="string" type="xs:string"/>
                    <xs:element ref="c:list"/>
                </xs:choice>
                <xs:element minOccurs="0" ref="c:int"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

    <xs:element name="list">
        <xs:complexType>
            <xs:sequence>
                <xs:choice minOccurs="0" maxOccurs="unbounded">
                    <xs:element minOccurs="0" maxOccurs="unbounded" ref="c:classBean"/>
                    <xs:element minOccurs="0" maxOccurs="unbounded" name="string" type="xs:string"/>
                </xs:choice>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
    <xs:element name="int" type="xs:integer"/>

</xs:schema>

对于验证，我使用以下代码片段：

SchemaFactory schemaFactory =  SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = schemaFactory.newSchema(schemaFile);
Validator validator = schema.newValidator();
validator.validate(xmlFile);

抛出以下异常，这表明在给定Schema的情况下XML文件无效：

org.xml.sax.SAXParseException; systemId: file:/C:/xml.xml; lineNumber: 2; columnNumber: 10; cvc-elt.1: Cannot find the declaration of element 'success'.

我不明白这条消息，因为在第2行我可以找到'success'元素。有人可以帮忙吗？

根据您的Schema，您的XML是错误的，请看一下：

<强> XML：

<classBean>
  <id>http://purl.bioontology.org/ontology/provisional/9cc8b147-e193-4d23-a3a1-9da34eeeb5a9</id>
  <fullId>http://purl.bioontology.org/ontology/provisional/9cc8b147-e193-4d23-a3a1-9da34eeeb5a9</fullId>
  <label>OzbbBugGbIINcdpSY</label>
  <synonyms>
    <string>ux0fBN http://www.ggiodpc.com/www.6shpFpANPwYnffbs9P5rsRN67oJWDZuQ.com.php</string>
  </synonyms>
  <definitions>
    <string>ux0fBN http://www.ggiodpc.com/www.6shpFpANPwYnffbs9P5rsRN67oJWDZuQ.com.php</string>
  </definitions>

<强> XSD

  <xs:element name="classBean">
    <xs:complexType>
      <xs:choice minOccurs="0" maxOccurs="unbounded">
        <xs:element ref="c:fullId" maxOccurs="1" minOccurs="0"/>
        <xs:element ref="c:id" maxOccurs="1" minOccurs="0"/>
        <xs:element ref="c:label" maxOccurs="1" minOccurs="0"/>
        <xs:element ref="c:relations" maxOccurs="1" minOccurs="0"/>
        <xs:element name="type" type="xs:string" maxOccurs="1" minOccurs="0"/>
      </xs:choice>
    </xs:complexType>
  </xs:element>

注意：'synonyms'和'definitions'不是'classBean'元素的有效子。

同样的事情对于'entry'元素，其中'date'和'null'作为子元素但是根据模式它不是valide。还有一些错误。

SAX Parser可能无法反映错误的错误行数。

为什么XML验证失败？
