C++ 用Schema验证xml文件问题（MSXML）

oodreamy 2013-07-24 10:36:11

msxml里有没有现成的库可以根据自己定义的schema验证xml？没有的话是不是只能按自己特定的schema写程序去验证？
以下是从网上找的代码，其中有schema与xml的关联啊，但为什么无论xml文件有没有错，都会加载成功，包括节点顺序错误、数据类型不对等等这些错误都检测不出来。求解啊！
CString scmFile = "schema.xsd";
CString xmlFile = "student.xml";
_variant_t vFile((LPCTSTR)xmlFile);

// 创建 schema
MSXML2::IXMLDOMSchemaCollectionPtr pSchema ;
pSchema.CreateInstance(__uuidof(XMLSchemaCache60));

// 加载 schema 文件，或者以文件名为参数
pSchema ->add(_bstr_t("http://tempuri.org/schema.xsd"),_variant_t((LPCTSTR )scmFile));

// 创建文件组件
MSXML2 ::IXMLDOMDocumentPtr pDoc ;
pDoc .CreateInstance (__uuidof(DOMDocument60));
pDoc ->async = VARIANT_FALSE ;
pDoc ->validateOnParse = VARIANT_TRUE ;

// 关联 xml 和 schema
MSXML2 ::IXMLDOMDocument2Ptr pDoc2 = pDoc;
pDoc2->schemas = pSchema.GetInterfacePtr();

// 加载文件和判断
VARIANT_BOOL bRet = pDoc ->load(vFile);
if (bRet == VARIANT_TRUE )
{
MessageBox(NULL,_T("xml文件加载成功！"),_T("Information"),MB_OK|MB_ICONINFORMATION);
return true;
}
else
{
CString strError ;
MSXML2 ::IXMLDOMParseErrorPtr pError = pDoc ->parseError ;
strError .Format (
_T ("xml文件加载失败： code=%d, reson=%s" ),
pError ->errorCode , (LPCTSTR)pError ->reason );
MessageBox(NULL,strError,_T("Information"),MB_OK|MB_ICONINFORMATION);
return false;
}

怎么没人理？？？急求指点啊！！！

XML越来越热，关于XML的基础教程网络上也随处可见。可是一大堆的概念和术语往往让人望而生畏，很多朋友问我：XML到底有什么用，我们是否需要学习它？我想就我个人学习过程的心得和经验，写一篇比较全面的介绍文章。首先有两点是需要肯定的：　　第一：XML肯定是未来的发展趋势，不论是网页设计师还是网络程序员，都应该及时学习和了解，等待只会让你失去机会；　　第二：新知识肯定会有很多新概念，尝试理解和接受，您才可能提高。不要害怕和逃避，毕竟我们还年轻。　　本文共分五大部分。分别是XML快速入门，XML的概念，XML的术语，XML的实现，XML的实例分析。最后附录介绍了XML的相关资源。作者站在普通网页设计人员的角度，用平实生动的语言，向您讲述XML的方方面面，帮助你拨开XML的神秘面纱，快速步入XML的新领域。 • 第一章:XML快速入门 • 一. 什么是XML？ • 二. XML是新概念吗？ • 三. 使用XML有什么好处？ • 四. XML很难学吗？ • 五. XML和HTML的区别 • 六. XML的严格格式 • 七. 关于XML的更多 • 第二章:XML概念 • 一. 扩展性 • 二. 标识 • 三. 语言 • 四. 结构化 • 五. Meta数据 • 六. 显示 • 七. DOM • 第三章:XML的术语 • 导言 • 一.XML文档的有关术语 • 二.DTD的有关术语 • 第四章:XML的语法 • 一.XML语法规则 • 二.元素的语法 • 三.注释的语法 • 四.CDATA的语法 • 五.Namespaces的语法 • 六.entity的语法 • 七.DTD的语法 • 第五章:XML实例解释 • 一.定义新标识 • 二.建立XML文档 • 三.建立相应的HTML文件 • 第六章:XML相关资源五. XML和HTML的区别 XML和HTML都来自于SGML，它们都含有标记，有着相似的语法，HTML和XML的最大区别在于：HTML是一个定型的标记语言，它用固有的标记来描述，显示网页内容。比如表示首行标题，有固定的尺寸。相对的，XML则没有固定的标记，XML不能描述网页具体的外观，内容，它只是描述内容的数据形式和结构。这是一个质的区别：网页将数据和显示混在一起，而XML则将数据和显示分开来。我们看上面的例子，在myfile.htm中，我们只关心页面的显示方式，我们可以设计不同的界面，用不同的方式来排版页面，但数据是储存在myfile.xml中，不需要任何改变。 (如果你是程序员，你会惊讶的发现，这与模块化面向对象编程的思想极其相似！其实网页何尝不是一种程序呢？) 正是这种区别使得XML在网络应用和信息共享上方便，高效，可扩展。所以我们相信，XML做为一种先进的数据处理方法，将使网络跨越到一个新的境界。六. XML的严格格式吸取HTML松散格式带来的经验教训，XML一开始就坚持实行"良好的格式"。我们先看HTML的一些语句，这些语句在HTML中随处可见: 1. sample 2.sample 3.sample 4.samplar 在XML文档中，上述几种语句的语法都是错误的。因为: 1.所有的标记都必须要有一个相应的结束标记； 2.所有的XML标记都必须合理嵌套； 3.所有XML标记都区分大小写； 4.所有标记的属性必须用""括起来；所以上列语句在XML中正确的写法是 1. sample 2.sample 3.sample 4.samplar 　　另外，XML标记必须遵循下面的命名规则: 1.名字中可以包含字母、数字以及其它字母； 2.名字不能以数字或"_" (下划线) 开头； 3.名字不能以字母 xml (或 XML 或 Xml ..) 开头； 4.名字中不能包含空格。在XML文档中任何的差错，都会得到同一个结果：网页不能被显示。各浏览器开发商已经达成协议，对XML实行严格而挑剔的解析，任何细小的错误都会被报告。你可以将上面的myfile.xml修改一下，比如将改为，然后用IE5直接打开myfile.xml，会得到一个出错信息页面： XML轻松学习手册 ajie

TinyXml是一个基于DOM模型的、非验证的轻量级C++解释器。 1. SAX和DOM 目前XML的解析主要有两大模型：SAX和DOM。其中SAX是基于事件的，其基本工作流程是分析XML文档，当发现了一个新的元素时，产生一个对应事件，并调用相应的用户处理函数。这种方式占用内存少，速度快，但用户程序相应得会比较复杂。而DOM（文档对象模型），则是在分析时，一次性的将整个XML
