用XSL解析XML

       
strXmlPath=GetUnitFilePath(courseId,subCourseId,unitId);          
          
strXSLTFile=GetCrsQuestion(courseSettingInfo,courseId,subCourseId).File;          
  
System.Xml.XPath.XPathDocument xpathDoc = new XPathDocument(strXmlPath);          
   
XsltArgumentList xslArg = new XsltArgumentList();          
xslArg.AddParam("ParamQuestionNo","",strParamQuestionNo);          
  
XslTransform xslt = new XslTransform();          
xslt.Load(strXSLTFile);          
      
MemoryStream memStream = new MemoryStream();          
 
xslt.Transform(xpathDoc, xslArg,memStream, null);          
     
memStream.Seek( 0, SeekOrigin.Begin );           
StreamReader sr = new StreamReader( memStream );          
string strOutHtml = sr.ReadToEnd();          
       
memStream.Close();          
sr.Close();          
     
return strOutHtml;
