如何针对XML模式验证XML文件时获取错误的行号

我找到了这个

http://www.herongyang.com/XML-Schema/Xerces2-XSD-Validation-with-
XMLReader.html

似乎提供以下详细信息（包括行号）

Error:   Public ID: null   System ID: file:///D:/herong/dictionary_invalid_xsd.xml   Line number: 7   Column number: 22   Message: cvc-datatype-valid.1.2.1: 'yes' is not a valid 'boolean'    value.

使用此代码：

import java.io.IOException;import org.xml.sax.XMLReader;import org.xml.sax.helpers.DefaultHandler;import org.xml.sax.helpers.XMLReaderFactory;import org.xml.sax.SAXException;import org.xml.sax.SAXParseException;class XMLReaderValidator {   public static void main(String[] args) {      String parserClass = "org.apache.xerces.parsers.SAXParser";      String validationFeature          = "http://xml.org/sax/features/validation";      String schemaFeature          = "http://apache.org/xml/features/validation/schema";      try {         String x = args[0];         XMLReader r = XMLReaderFactory.createXMLReader(parserClass);         r.setFeature(validationFeature,true);         r.setFeature(schemaFeature,true);         r.setErrorHandler(new MyErrorHandler());         r.parse(x);      } catch (SAXException e) {         System.out.println(e.toString());       } catch (IOException e) {         System.out.println(e.toString());       }   }   private static class MyErrorHandler extends DefaultHandler {      public void warning(SAXParseException e) throws SAXException {         System.out.println("Warning: ");          printInfo(e);      }      public void error(SAXParseException e) throws SAXException {         System.out.println("Error: ");          printInfo(e);      }      public void fatalError(SAXParseException e) throws SAXException {         System.out.println("Fattal error: ");          printInfo(e);      }      private void printInfo(SAXParseException e) {         System.out.println("   Public ID: "+e.getPublicId());         System.out.println("   System ID: "+e.getSystemId());         System.out.println("   Line number: "+e.getLineNumber());         System.out.println("   Column number: "+e.getColumnNumber());         System.out.println("   Message: "+e.getMessage());      }   }}
