我想编写一个接受这样的
XML文档的模式:
<plugin> <label text="blabla" /> <line /> <break /> <textBox name="mytextBox" length="8" required="true" /> <checkBox name="mycheckBox" checked="true" /> <comboBox name="mycombo"> <option value="one">Option One</option> <option value="two" selected="true">Option One</option> </comboBox> <break /> </plugin>
所以我希望插件包含set {comboBox,checkBox,textBox,label,line,break}的元素.
我写过这个XSD,但这是错的:
<?xml version="1.0" encoding="utf-8"?> <xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"> <xs:element name="plugin"> <xs:complexType> <xs:sequence> <xs:choice> <xs:element name="line" /> <xs:element name="break" /> <xs:element name="label"> <xs:complexType> <xs:attribute name="text" type="xs:string" /> <xs:attribute name="bold" type="xs:boolean" /> <xs:attribute name="width" type="xs:positiveInteger" /> </xs:complexType> </xs:element> <xs:element name="textBox"> <xs:complexType> <xs:attribute name="name" type="xs:string" /> <xs:attribute name="width" type="xs:positiveInteger" /> <xs:attribute name="text" type="xs:string" /> <xs:attribute name="length" type="xs:positiveInteger" /> <xs:attribute name="required" type="xs:boolean" /> </xs:complexType> </xs:element> <xs:element name="comboBox"> <xs:complexType> <xs:sequence> <xs:element name="option" nillable="true" minOccurs="0" maxOccurs="unbounded"> <xs:complexType> <xs:simpleContent msdata:ColumnName="option_Text" msdata:Ordinal="2"> <xs:extension base="xs:string"> <xs:attribute name="value" type="xs:string" /> <xs:attribute name="selected" type="xs:boolean" /> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> </xs:sequence> <xs:attribute name="name" type="xs:string" /> <xs:attribute name="width" type="xs:positiveInteger" /> </xs:complexType> </xs:element> <xs:element name="checkBox"> <xs:complexType> <xs:attribute name="name" type="xs:string" /> <xs:attribute name="checked" type="xs:boolean" /> <xs:attribute name="text" type="xs:string" /> <xs:attribute name="width" type="xs:positiveInteger" /> </xs:complexType> </xs:element> </xs:choice> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:UseCurrentLocale="true"> <xs:complexType> <xs:choice minOccurs="0" maxOccurs="unbounded"> <xs:element ref="plugin" /> </xs:choice> </xs:complexType> </xs:element> </xs:schema>
我用this validator tool测试了它…
但它说:
“cvc-complex-type.2.4.d: Invalid content was found starting with
element ‘line’. No child element is expected at this point.”
那么……怎么了?我不明白这个消息.什么儿童元素在哪一点?
