中文XML论坛--[求助]跪求！：如何验证xml的正确，DOM可以吗？

我正在在.net平台下用c#编写程序，程序要读写xml文件，我对xml也编写了Schema，在写xml时需要验证它的正确性，我想问一下，用DOM可以验证吗？如果不行，那用什么可以来验证呢？谢谢大家了，我很着急，谢谢了

DOM不支持验证。你的使用支持验证的解析器, 比如JAXP 1.2, 进行xml文档验证
你要是用java可以这样。.net里的没试过。
----------------------------------------------------------------------------------------------------------
类ValidateXML的静态方法validate参数一(xml文档)、参数二(schema文档)，静态属性validatechecksuccess标识验证结果。

import java.lang.String;
import java.io.*;
import org.xml.sax.*;
import javax.xml.parsers.*;

public class ValidateXML {
static String SCHEMA_LANGUAGE = "http://java.sun.com/xml/jaxp/properties/schemaLanguage";

static String XML_SCHEMA = "http://www.w3.org/2001/XMLSchema";

static String SCHEMA_SOURCE = "http://java.sun.com/xml/jaxp/properties/schemaSource";

static boolean validatechecksuccess;

   static void validate(String xmlfilename, String shemafilename) {
      validatechecksuccess = true;
      File input = new File(xmlfilename);
      File schema = new File(shemafilename);
      SAXParserFactory factory = SAXParserFactory.newInstance();
      factory.setNamespaceAware(true);
      factory.setValidating(true);
      try {
         SAXParser parser = factory.newSAXParser();
         parser.setProperty(SCHEMA_LANGUAGE, XML_SCHEMA);
         parser.setProperty(SCHEMA_SOURCE, schema);
         parser.parse(input, new SAXErrorPrinter());
      } catch (SAXNotRecognizedException e) {
         System.err.println("Unknown property specified:" + e.getMessage());
      } catch (SAXNotSupportedException e) {
         System.err.println("Unsupported property specified:"
               + e.getMessage());
      } catch (ParserConfigurationException e) {
         System.err.println("Your SAX parser is not JAXP 1.2 compliant."
               + e.getMessage());
      } catch (SAXException e) {
         System.err.println("Your SAX parser is not JAXP 1.2 compliant."
               + e.getMessage());
      } catch (IOException e) {
         System.err.println("Your SAX parser is not JAXP 1.2 compliant."
               + e.getMessage());
      } catch (Exception e) {
         System.err.println("Your SAX parser is not JAXP 1.2 compliant."
               + e.getMessage());
      }
   }
}

其中注册的ErrorHandler处理SAXParseException
import java.text.*;
import org.xml.sax.*;
import org.xml.sax.helpers.*;

public class SAXErrorPrinter extends DefaultHandler {
private MessageFormat message = new MessageFormat("({0}: {1}, {2}): {3}");

   private void print(SAXParseException x) {
      String msg = this.message.format(new Object[] { x.getSystemId(),
            new Integer(x.getLineNumber()),
            new Integer(x.getColumnNumber()), x.getMessage() });
      System.err.println(msg);
      ValidateXML.validatechecksuccess = false;
   }

   public void warning(SAXParseException x) {
      this.print(x);
   }

   public void error(SAXParseException x) {
      this.print(x);
   }

   public void fatalError(SAXParseException x) throws SAXParseException {
      this.print(x);
      throw x;
   }
}

                + loadingFileName + "'.", args.Exception);
        }
