webservice 第二讲schema

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" 
		targetNamespace="http://www.example.org/01"
		xmlns:tns="http://www.example.org/01" 
		elementFormDefault="qualified">
	<element name="user">
		<complexType>
			<sequence>
				<element name="id" type="int"/>
				<element name="username" type="string"/>
				<element name="born" type="date"/>
			</sequence>
		</complexType>
	</element>
</schema>

1.http://www.w3.org/2001/XMLSchema
Schema 默认命名空间,不能修改,但是可以增加前缀。如何增加前缀之后所有的element元素都要增加浅醉
2.targetNamespace="http://www.example.org/01"
自己这个文档的命令空间,可以方便其他xml和schema文件的引用
3.xmlns:tns="http://www.example.org/01"
此处的名称和自己的命名空间一直,增加了tns的前缀,此时如果要引用当前文件创建的类型,需要加上tns前缀

<?xml version="1.0" encoding="UTF-8"?>
<user xmlns="http://www.example.org/01"
	  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	  xsi:schemaLocation="http://www.example.org/01 01.xsd">
	 <id>1</id>
	 <username>wxh</username>
	 <born>1998-12-12</born>
</user>

4.复杂的schema文件和xml文件相关配置

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" 
		targetNamespace="http://www.example.org/04" 
		xmlns:tns="http://www.example.org/04" 
		elementFormDefault="qualified">
		
	<element name="person" type="tns:personType"/>
	
	<complexType name="personType">
		<sequence>
			<element name="name" type="string"/>
			<element name="age" type="tns:ageType"/>
			<element name="email" type="tns:emailType"/>
		</sequence>
		<attribute name="sex" type="tns:sexType"/>
	</complexType>
	
	<simpleType name="emailType">
		<restriction base="string">
			<pattern value="(\w+\.*)*\w+@\w+\.[A-Za-z]{2,6}"/>
			<minLength value="6"/>
			<maxLength value="255"/>
		</restriction>
	</simpleType>
	
	<simpleType name="ageType">
		<restriction base="int">
			<minInclusive value="1"/>
			<maxExclusive value="150"/>
		</restriction>
	</simpleType>
	
	<simpleType name="sexType">
		<restriction base="string">
			<enumeration value="男"/>
			<enumeration value="女"/>
		</restriction>
	</simpleType>
</schema>

<?xml version="1.0" encoding="UTF-8"?>
<person xmlns="http://www.example.org/04"
	  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	  xsi:schemaLocation="http://www.example.org/04 04.xsd" sex="男">
	 <name>搜索</name>
	 <age>149</age>
	 <email>[e-mail]</email>
</person>

54.复杂的schema文件

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
		targetNamespace="http://www.example.org/classroom" 
		xmlns:tns="http://www.example.org/classroom" 
		elementFormDefault="qualified">
	<xsd:element name="student" type="tns:studentType"/>
	
	<xsd:complexType name="studentType">
		<xsd:sequence>
			<xsd:element name="name" type="xsd:string"/>
			<xsd:element name="sex" type="tns:sexType"/>
		</xsd:sequence>
	</xsd:complexType>
	
	<xsd:simpleType name="sexType">
		<xsd:restriction base="xsd:string">
			<xsd:enumeration value="男"/>
			<xsd:enumeration value="女"/>
		</xsd:restriction>
	</xsd:simpleType>
</xsd:schema>

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
		targetNamespace="http://www.example.org/classroom" 
		xmlns:tns="http://www.example.org/classroom" 
		elementFormDefault="qualified">
	<xsd:include schemaLocation="student.xsd"/>
	
	<xsd:element name="classroom" type="tns:classroomType"/>
	
	<xsd:complexType name="classroomType">
		<xsd:sequence>
			<xsd:element name="grade" type="tns:gradeType"/>
			<xsd:element name="name" type="xsd:string"/>
			<!--  <xsd:element name="stus">
				<xsd:complexType>
					<xsd:sequence minOccurs="1" maxOccurs="unbounded">
						<xsd:element name="student" type="tns:studentType"/>
					</xsd:sequence>
				</xsd:complexType>
			</xsd:element>
			-->
			<xsd:sequence minOccurs="1" maxOccurs="unbounded">
				<xsd:element name="student" type="tns:studentType"/>
			</xsd:sequence>
		</xsd:sequence>
	</xsd:complexType>
	
	<xsd:simpleType name="gradeType">
		<xsd:restriction base="xsd:int">
			<xsd:minInclusive value="2000"/>
			<xsd:maxInclusive value="3000"/>
		</xsd:restriction>
	</xsd:simpleType>
</xsd:schema>
