Question

我目前正在学习XML，并且正在尝试创建一个表示库的简单XML文件。我收到的无效内容从XML中的元素“ librarian”错误开始。我知道以前曾有人问过同样的问题，但是他们的回答并不能解决我的问题，因为我似乎还有其他原因。我的XSD文件如下

    <?xml version="1.0"?>
<xs:schema version="1.0"
           xmlns:xs="http://www.w3.org/2001/XMLSchema"
           targetNamespace="http://www.mybooks.org"
           xmlns="http://www.mybooks.org"
           elementFormDefault="qualified">

    <xs:element name="library">
        <xs:complexType> 
            <xs:sequence> 
                <xs:element name="librarian">
                    <xs:complexType>
                        <xs:attribute name="name" use="required"/>
                        <xs:attribute name="email" use="optional"/>
                    </xs:complexType> 
                </xs:element>
                <xs:element name="book" minOccurs = "1" maxOccurs = "unbounded">
                    <xs:complexType>
                        <xs:sequence>
                            <xs:element name="part" minOccurs = "1" maxOccurs = "unbounded">
                                <xs:complexType>
                                    <xs:sequence>
                                        <xs:element name="chapter" minOccurs = "1" maxOccurs = "unbounded">
                                            <xs:complexType>
                                                <xs:sequence>
                                                    <xs:element name="section" minOccurs = "1" maxOccurs = "unbounded">
                                                        <xs:complexType>
                                                            <xs:sequence>
                                                                <xs:element name="paragraph" type="xs:string" minOccurs = "1" maxOccurs = "unbounded"/>
                                                            </xs:sequence>
                                                        </xs:complexType>
                                                    </xs:element>
                                                </xs:sequence>
                                                <xs:attribute name="title" use="required"/>
                                                <xs:attribute name="summary" use="required"/>
                                            </xs:complexType>
                                        </xs:element> 
                                    </xs:sequence>
                                    <xs:attribute name="title" use="required"/>
                                </xs:complexType>
                            </xs:element>
                        </xs:sequence>
                        <xs:attribute name="title" use="required"/>
                        <xs:attribute name="isbn" use="required"/>
                        <xs:attribute name="author" use="required"/>
                    </xs:complexType>
                </xs:element> 
            </xs:sequence>
            <xs:attribute name="location" use="required"/>
            <xs:attribute name="description" use="required"/>        
        </xs:complexType>
    </xs:element> 

</xs:schema>

我的XML文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<myDay:library xmlns:myDay ="http://www.mybooks.org"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.mybooks.org library.xsd" location = "Nasr City" description = "A Public Library">
    <librarian name = "Islam"/>
    <book title = "The Structure of Scientific Revolutions" isbn = "_100" author = "Thomas Kuhn">
        <part title = "I">
            <chapter title = "Paradigm" summary = "my summary">
                <section>
                    <paragraph> normal science </paragraph>
                </section>
            </chapter>
        </part>
    </book> 
</myDay:library>

我在这里做错了什么？是我在架构定义中出错还是在XML文件本身中？

在XML中找到与元素无效的内容
