Java 根据XML验证多个XSD

我目前正在努力解决编写一些单元测试来检查XSD是否对示例XML文件有效的问题。我发现以下错误：

org.xml.sax.SAXParseException；cvc elt.1:找不到元素“VMS”的声明。

我的XSD文件：

<?xml version="1.0" encoding="UTF-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <!-- Messages header -->

    <xs:complexType name="VMS_TYPE">
        <!-- Recipient of message -->
        <xs:attribute name="TO" type="xs:string"/>
        <!-- Sender of message -->
        <xs:attribute name="FR" type="xs:string" />
        <!-- Message identification number consists -->

        <!-- TODO - explain attribute meaning -->
        <xs:attribute name="MD" type="xs:string" />
    </xs:complexType>

</xs:schema>

第二

<?xml version="1.0" encoding="UTF-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <xs:include schemaLocation="vms_header.xsd" />

    <!-- Alarm message -->

                    <xs:element name="ALR" type="ALR_BODY_TYPE" />
                </xs:sequence>
            </xs:extension>

            <xs:attribute name="ASOS" type="xs:int"/>
    </xs:complexType>

</xs:schema>

第三

和我的XML示例文件：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<VMS TO="CV0001" FR="CAR001" VN="CAR001201406040001" OD="2014-06-04" OT="12:14" MD="+3465104505050">
    <ALR BAT="0" TEM="0" GPS="0" SOS="0" CV="0" MOD="0" FGPS="0" FBAT="0" FALM="0" FSOS="0" FFW="0" ASOS="0"/>
</VMS>

这对我很有用，jdk1.8.0\u 20

./third.xsd   # probably not the real name, but you no tell
./types/alr_msg_type.xsd
./types/vms_header.xsd

public static void main( String[] args ) throws Exception {
  Handler handler = new Handler();
  DocumentBuilder parser =
    DocumentBuilderFactory.newInstance().newDocumentBuilder();
  parser.setErrorHandler( handler );
  try {
    Document document = parser.parse(new File("x.xml"));
    SchemaFactory factory = 
      SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
    Source schemaFile = new StreamSource(new File("third.xsd"));
    Schema schema = factory.newSchema(schemaFile);
    Validator validator = schema.newValidator();
    validator.setErrorHandler( handler );
    // validate the DOM tree
    try {
      validator.validate(new DOMSource(document));
    } catch (SAXException e) {
      // ...
      System.out.println( "VAlidation error" );
    }
  } catch (SAXParseException e) {
    // syntax error in XML document     
    System.out.println( "Syntax error" );
  }
}

我使用了以下代码（使用JDK1.8.0_11）：

结果是：

语法错误 org.xml.sax.SAXParseException；行号：6；栏目号：45；src resolve:无法将名称“ALR_TYPE”解析为（n）“TYPE definition”组件

}
