B2MML 標準 (具体的にはマテリアル スキーマ) の XSD スキーマの 1 つを使用して XML ファイルを検証する際に問題が発生します。コードは他の XSD で動作しますが、B2MML では動作しません。検証を処理する方法は次のとおりです。
public class XMLvalidate {
public static void Xml2String(String xmlFile){
// Danner JAVA DOM XML Parser
DocumentBuilderFactory builderFactory =
DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
try {
builder = builderFactory.newDocumentBuilder();
} catch (ParserConfigurationException e) {
e.printStackTrace();
}
// Changes the XML file to XML DOM standard
try {
Document document = builder.parse(
new FileInputStream(new File(xmlFile)));
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
// Make the DOM XML file readable
StreamResult result = new StreamResult(new StringWriter());
DOMSource source = new DOMSource(document);
transformer.transform(source, result);
String xmlString = result.getWriter().toString();
System.out.println(xmlString);
} catch (SAXException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (TransformerConfigurationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (TransformerFactoryConfigurationError e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (TransformerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void XMLValidator(String xmlFile, String validationFile)throws SAXException, IOException{
String language = XMLConstants.W3C_XML_SCHEMA_NS_URI;
SchemaFactory factory = SchemaFactory.newInstance(language);
((factory.newSchema(new File(validationFile))).newValidator()).validate(new StreamSource(new File(xmlFile)));
}
public static void main(String [] args){
boolean flag = true;
try{
try{XMLValidator("src\\Material.xml", "src\\B2MML-V0600-Material.xsd");}
catch (SAXException e){ flag = false; }
catch (IOException e) { flag = false; }
System.out.println("XML fil is valid : " + flag);
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

私たちの XML ファイルは、XSD ファイルから自動生成されます。XMLスパイ。
B2MML で動作しないのはなぜですか? 前もって感謝します。
