xml架构验证问题

Question

我正在尝试使用xml架构验证器，但我收到一条错误消息，提示“文件过早结束”，我似乎无法找到此错误的位置。 这里是我的xsd文件

<?xml version="1.0" encoding="UTF-8" standalone="no"?> 
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
<xs:element name="orders">

     </xs:restriction> 
     </xs:simpleType> 
    </xs:element> 
    <xs:element name = "speech" type="xs:language"> 
     <xs:simpleType name = "language"> 
     <xs:restriction base = "string"> 
      <xs:enumeration value = "Spanish" /> 
      <xs:enumeration value = "Chinese" /> 
      <xs:enumeration value = "English" />

      <xs:enumeration value = "French" /> 
     </xs:restriction> 
     </xs:simpleType> 
    </xs:element> 
    </xs:sequence> 
    </xs:complexType> 
</xs:element> 
</xs:element> 
</xs:schema> 

和错误的位置说这是上线-1，-1。

这里是我的DTD文件，以防万一，以及

<?xml version="1.0"?> 
<!DOCTYPE orders [ 
<!ELEMENT orders (order+)> 
<!ELEMENT order (case, batteries, recharger, arm, camera, 
speech)> 
<!ELEMENT case (#PCDATA)> 
<!ELEMENT batteries (#PCDATA)> 
<!ELEMENT recharger (#PCDATA)> 
<!ELEMENT arm (reach)> 
<!ELEMENT reach (#PCDATA)> 
<!ELEMENT camera (#PCDATA)> 
<!ELEMENT speech (#PCDATA)> 
]> 

和误差不说哪个文件中的错误的来源。这是我正在使用的验证器。 http://corefiling.com/opensource/schemaValidate.html

我猜因为我不能使用我的dtd，这里是我的xml文件。

<?xml version="1.0" encoding="UTF-8"?>

    <order> 
    <case> Strawberry </case> 
    <batteries> 2 </batteries>

Answer 1

XSD架构是无效的，你不能有嵌套元素这样

<xs:element name="orders"> 
<xs:element name ="order" maxOccurs="unbounded"> 

事实上的模式中有错误的负载。 XML Schema很难处理，手工编写它们并不实际，我建议使用像Liquid XML Studio这样的graphical XML schema editor。

注： 我觉得你应该的模式是这样的： -
