    发贴心情 指定XSD验证XML时:属性不让出现在某元素中

    各位路过的大仙~~

    刚学XML,我用XSD定义了一个格式~~~来显示产品~~
    test.xsd
    [CODE=xml]
    <?xml version="1.0" encoding="UTF-8"?>
    <pm:schema xmlns:pm="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    targetNamespace="http://www.example.org/test"
    xmlns="http://www.example.org/test"
    elementFormDefault="qualified">
        <pm:element name="ProductShow">
            <pm:complexType mixed="true">
                <pm:sequence>
                    <pm:element name="pClassId" type="simpleElement" />
                    <pm:element name="showName" type="simpleElement" />
                    <pm:element name="animation" type="MyAnimate"/>
                    <!--start productFamily  #####################-->
                    <pm:element name="productFamily">
                        <pm:complexType mixed="true">
                        <pm:sequence>
                        <!--start perProduct *******************-->
                        <pm:element name="perProduct" minOccurs="1" maxOccurs="unbounded">
                            <pm:complexType mixed="true">
                            <pm:sequence>
                                <pm:element name="pId" type="simpleElement" />
                                <pm:element name="pFileName" type="simpleElement" />
                                <pm:element name="pFileSrc" type="simpleElement" />
                                <pm:element name="description" type="simpleElement" />
                            </pm:sequence>
                            <pm:attribute name="perPOrder" type="pm:integer" use="required" />
                            </pm:complexType>
                        </pm:element>
                        <!--over perProduct ********************-->
                        </pm:sequence>
                        </pm:complexType>
                    </pm:element>
                    <!--over productFamily #####################-->
                    <pm:element name="downloadSrc" type="simpleElement" />
                    <pm:element name="remarks" type="simpleElement" />
                    <!--Support for custom extensions,format"name=value" -->
                    <pm:element name="otherGroups">
                    <pm:complexType>
                    <pm:sequence>
                    <pm:element name="otherElement" minOccurs="0" maxOccurs="unbounded">
                        <pm:complexType>
                        <pm:sequence>
                            <pm:element name="key" type="pm:string" />
                            <pm:element name="value" type="pm:string" />
                        </pm:sequence>
                        </pm:complexType>
                    </pm:element>
                    </pm:sequence>
                    </pm:complexType>
                    </pm:element>
                    <!-- over custom extensions -->
                </pm:sequence>
            </pm:complexType>
        </pm:element>
        <!-- ++++++++start define attribute and others+++++++ -->
        <pm:simpleType name="MyAnimate">
            <pm:restriction base="pm:string">
                <pm:enumeration value="是" />
                <pm:enumeration value="否" />
            </pm:restriction>
        </pm:simpleType>
        <pm:complexType name="simpleElement">
            <pm:sequence>
                <pm:element name="value" type="pm:string" />
                <pm:element name="desc" type="pm:string" default="" />
            </pm:sequence>
        </pm:complexType>    
    </pm:schema>


    [/CODE]

    然后根据这个手敲了一个XML——product1.xml
    [CODE=xml]
    <?xml version="1.0" encoding="UTF-8"?>
    <ProductShow xmlns="http://www.example.org/test" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.example.org/test test.xsd">
    <pClassId>
        <value>1234</value>
        <desc>the product id</desc>
    </pClassId>
    <showName >
        <value>XXX产品图</value>
        <desc>the name displayed on the web of product</desc>
    </showName>
    <animation>是</animation>
    <productFamily>
        <perProduct perPOrder="1">
            <pid></pid>
            <pFileName>1.png</pFileName>    
            <pFileSrc>./test</pFileSrc>
            <description></description>
        </perProduct>
        <perProduct perPOrder="2">
            <pid></pid>
            <pFileName>2.png</pFileName>    
            <pFileSrc>./test</pFileSrc>
            <description></description>
        </perProduct>
        <perProduct perPOrder="3">
            <pid></pid>
            <pFileName>3.png</pFileName>    
            <pFileSrc>./test</pFileSrc>
            <description></description>
        </perProduct>
        <perProduct perPOrder="4">
            <pid></pid>
            <pFileName>4.png</pFileName>    
            <pFileSrc>./test</pFileSrc>
            <description></description>
        </perProduct>
        <perProduct perPOrder="5">
            <pid></pid>
            <pFileName>5.png</pFileName>    
            <pFileSrc>./test</pFileSrc>
            <description></description>
        </perProduct>
    </productFamily>
    <downloadSrc >
        <value></value>
        <desc>the full URL of data to product for download</desc>
    </downloadSrc>
    <remarks>
        <value></value>
        <desc>the remarks of product</desc>
    </remarks>
    <others>
    <!-- "the extension for others,can contain other elements" -->
    </others>
    </ProductShow>
    [/CODE]

    结果,我在验证我的XML是否符合XSD的时候~~会报错·~如下
    [CODE=java]
    org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'pid'. One of '{"http://www.example.org/CIPAS_Products_XML_SCH":pId}' is expected.

    [/CODE]

    说不能将order属性加入到该元素·~~囧~~这事为什么啊? 求解决办法·~~
    另,附上我用来验证的java方法:
    [CODE=java]
    import java.io.File;
    import java.io.IOException;

    import javax.xml.transform.Source;
    import javax.xml.transform.stream.StreamSource;
    import javax.xml.validation.Schema;
    import javax.xml.validation.SchemaFactory;
    import javax.xml.validation.Validator;

    import org.xml.sax.SAXException;

    public class ValidateXML {
         
         public boolean validateXML(String xsdpath,String xmlpath) throws SAXException,IOException{
            //建立schema工厂
            SchemaFactory schemaFactory=SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema");
            //建立验证文档文件对象,利用此文件对象所封装的文件进行schema验证
            File schemaFile=new File(xsdpath);
            //利用schema工厂,接收验证文档文件对象生成Schema对象
            Schema schema=schemaFactory.newSchema(schemaFile);
            //通过Schema产生针对于此Schema的验证器,利用schenaFile进行验证
            Validator validator=schema.newValidator();
            //得到验证的数据源
            Source source=new StreamSource(xmlpath);
            //开始验证,成功输出success!!!,失败输出fail
            try{
             
             validator.validate(source);
             
            }catch(Exception ex){
             
             ex.printStackTrace();
             
            }
                  return true;
          }
          
         public static void main(String[] args) {
            String xmlDir="product1.xml";
            String xsdDir="test.xsd";
            boolean out;
            try {
                out=new ValidateXML().validateXML(xsdDir, xmlDir);
                if (out) {
                    System.out.println("the 'product1.xml' is format to 'test.xsd'!");
                }else {
                    System.err.println("it's so pity! something was wrong!");
                }
            } catch (SAXException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            
        }
         
        }

    [/CODE]
