6.【xml schema 】实例demo

xml

<?xml version="1.0" encoding="UTF-8"?>
<shiporder orderid="889923"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:noNamespaceSchemaLocation="w3ctest.xsd">
	<orderperson>George Bush</orderperson>
	<shipto>
		<name>John Adams</name>
		<address>Oxford Street</address>
		<city>London</city>
		<country>UK</country>
	</shipto>
	<item>
		<title>Empire Burlesque</title>
		<note>Special Edition</note>
		<quantity>1</quantity>
		<price>10.90</price>
	</item>
	<item>
		<title>Hide your heart</title>
		<quantity>1</quantity>
		<price>9.90</price>
	</item>
</shiporder>

我写的是下面的 是ok的

schema

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
	
	<xs:complexType name="shiporderinfo">
		<xs:sequence>
			<xs:element name="orderperson" type="xs:string"/>

			<xs:element name="shipto">
				<xs:complexType>
					<xs:sequence>
						<xs:element name="name" type="xs:string"/>
						<xs:element name="address" type="xs:string"/>
						<xs:element name="city" type="xs:string"/>
						<xs:element name="country" type="xs:string"/>
					</xs:sequence>
				</xs:complexType>
			</xs:element>

			<xs:element name="item" maxOccurs="unbounded">
				<xs:complexType>
					<xs:sequence>
						<xs:element name="title" type="xs:string"/>
						<xs:element name="note" type="xs:string" minOccurs="0"/>
						<xs:element name="quantity" type="xs:string"/>
						<xs:element name="price" type="xs:string"/>
					</xs:sequence>
				</xs:complexType>
			</xs:element>

		</xs:sequence>

		<xs:attribute name="orderid"  use="required">
		 	<xs:simpleType>
				<xs:restriction base="xs:string">
					<xs:pattern value="[0-9]{6}"/>
				</xs:restriction>
			</xs:simpleType>
		</xs:attribute>

	</xs:complexType>

	<xs:element name="shiporder" type="shiporderinfo"/>

</xs:schema>

但可以使用 定义type-name 的方式简写整个 type 必须是 xs:schema 的直接元素

<xs:schema xmlns="http://www.w3.org/2001/XMLSchema">
    <xs:simpleType name="orderidattr">
		<xs:restriction base="xs:string">
			<xs:pattern value="[0-9]{6}"/>
		</xs:restriction>
	</xs:simpleType>

	...

	<xs:element name="shiporder" type="shiporderinfo"/>
</xs:schema>

php 验证函数

<?php

$dom = new DOMDocument;
$dom->load('w3ctest.xml');
libxml_use_internal_errors(true);
if($dom->schemaValidate("w3ctest.xsd")){
	echo "validate";
}else{
	var_dump(libxml_get_errors());
}

ref="引用" 的用法

<xs:element name="orderperson" type="xs:string"/> <xs:element ref="orderperson"/>
