JAVA 全系列/第二阶段：JAVA 基础深化和提高/容器（旧） 10494楼

学了这次的视频，我了解了下一直不太懂的命名空间

命名空间的出现是为了解决dtd不能解决的xml的命名冲突问题，这次课的视频里，xsd文件没有定义自己的命名空间。

然后在book.xml中引入book.xsd的时候属性使用的是

xsi:noNamespaceSchemaLocation="book.xsd"

不指定命名空间，只指定用于模式校验的xsd文档的位置，这种写法，XML模式处理器已经可以校验到xml里的写法问题了。如图：具体报错：

The content of element 'book' is not complete. One of '{price}' is expected.

说明已经检验成功了

在这里老师用的是

xsi:noNamespaceSchemaLocation="{book.xsd}" 而这种写法在我的idea里面是报红的。至于视频里老师不报红，我猜测不同工具的不同文件，可能工具没有识别出来语法错误，把验证插件给关闭了。为什么老师要多此一举，使用java的相关类，SchemaFactory进行解析，是不是因为要让我们了解如果脱离eclipse或者相关IDE，没有XML解析器，在只有xml文件及xsd文件的基础上，java也可以完成使用schema对xml文档的校验。

（扩充：自己测试了一下似乎谷歌浏览器无法完成使用schema对xml文档的校验，不报任何错误。）

这点在视频里没有提到。。这里存在疑问：（******）

另外给大家一种使用命名空间的方式校验：targetNamespace在book.xsd中给当前命名空间起名字，名称任意：http://www.example.org/books 这个是可以更改的

<?xml version="1.0" encoding="UTF-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.example.org/books" 
elementFormDefault="qualified">
    <xs:element name="books">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="book" maxOccurs="unbounded">
                    <xs:complexType>
                        <xs:sequence>
                            <xs:element name="name" type="xs:string"></xs:element>
                            <xs:element name="author" type="xs:string"></xs:element>
                            <xs:element name="price" type="xs:double"></xs:element>
                        </xs:sequence>
                        <xs:attribute name="id" type="xs:positiveInteger"></xs:attribute>
                    </xs:complexType>
                </xs:element>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>

book.xml 使用命名空间http://www.example.org/books

<?xml version="1.0" encoding="UTF-8" ?>
<books xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://www.example.org/books"
        xsi:schemaLocation="http://www.example.org/books book.xsd">
    <book id="1001">
        <name>html的使用</name>
        <author>张三</author>
        <price>51.6</price>
    </book>
    <book id="1002">
        <name>css的使用</name>
        <author>李四</author>
        <price>40.6</price>
    </book>
</books>

注释掉第一个book元素的price元素

结果：具体报错：The content of element 'book' is not complete. One of '{"http://www.example.org/books":price}' is expected.
