XSD文档解析错误

Question

我试图使用Java验证xml文档是否符合xsd规范。

以下是我的java代码：

SchemaFactory factory = 
        SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema");

File schemaLocation = new File("XX_ASN.xsd");
    Schema schema = factory.newSchema(schemaLocation); //**Error occurs here**

Validator validator = schema.newValidator();


    String xmlFile="file://18828324.txt";
    Source source = new StreamSource(xmlFile);

    // 5. Check the document
    try {
        validator.validate(source);
        System.out.println(args[0] + " is valid.");
    }
    catch (SAXException ex) {
        System.out.println(args[0] + " is not valid because ");
        System.out.println(ex.getMessage());
    }  

这是我正在犯的错误

org.xml.sax.SAXParseException; systemId: file:/C:/workspace4.3/MMSV/XX_ASN.xsd; lineNumber: 14; columnNumber: 19; s4s-elt-must-match.1: The content of 'XXLocalDeliveryAsnPost' must match (annotation?, (simpleType | complexType)?, (unique | key | keyref)*)). A problem was found starting at: complexType.

下面是我的xsd文件：

这个问题发生在XXLocalDeliveryAsnPost的第二个complexType (第14行)的开头。

我在这里做错什么了？xsd文档是由其他人提供的，不能更改。

Answer 1

您发布的XSD在XXLocalDeliveryAsnPost元素下至少有五个匿名的XXLocalDeliveryAsnPost。解析器在遇到第二个解析器后，会举起手来，但是在那之后，它会遇到更多的问题。

如果我不得不猜的话，看上去像是有人做了一些快速的复制、粘贴和祈祷。

为了让您开始，让我们通过假设第一个xs:complexType的末尾是XXLocalDeliveryAsnPost内容模型定义的正确结尾来修复第一个问题

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
           elementFormDefault="qualified" attributeFormDefault="unqualified">
  <xs:element name="XXLocalDeliveryAsnPost">
    <xs:annotation>
      <xs:documentation>Post ASN data to XX Local Delivery</xs:documentation>
    </xs:annotation>
    <xs:complexType>
      <xs:sequence>
        <xs:element name="VendorId" type="xs:string">

        <!--  Add additional children elements here -->

        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

从其余的xs:complexTypes中，您可能想要将其他的子元素拉到上面注释中为它们标记的位置。或者，您可能需要将这些附加的xs:complexTypes与它们自己的元素或类型定义关联起来。这是一个太多的混乱，无法确定，但希望这将使你开始修理。

Answer 2

在<complexType>元素中有两个<element>元素--只允许一个。事情就是这么简单。

如果您提供了XSD应该描述的XML，我们可能能够修补XSD。

下面只是一个经过深思熟虑的猜测，但是无论“其他人”说什么，XML都必须修改。(你可能会礼貌地指出，在分发这些文件之前，可以简单、廉价地检查这些文件。)
