XML generation using TinyXML

[bogusbonafide]

I have written the following classes to generate an XML which is as below:

<JBEToOverseerRequest xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="file:///c:/Share/resquest.xsd">
    <ConfigParams>        
           <Param Name="OverseerConfJBEPortNum">1025</Param>
           <Param Name="OverseerConfHctHostname">10.31.225.163</Param>
           <Param Name="OverseerConfTestExecParallelism">5</Param>
           <Param Name="OverseerConfServerName">10.31.225.163</Param>
           <Param Name="OverseerDirectory">C:\Documents and Settings\Administrator\Desktop\Pocdemo</Param>
           <Param Name="OverseerConfKillThreadUsingKillerThread">Yes</Param>
        
           <Param Name="OverseerTimeoutCleanup">yes</Param>
     </ConfigParams>
    
     <Requests>
         <Request>
              <RequestID>HC1001</RequestID>
              <Host>hct-nw-server</Host>
              <Parameters>
                  <Param Name="RequestNumber">1</Param>
                  <Param Name="TimeOut">120</Param>
              </Parameters>
        </Request>
        
        <Request>
              <RequestID>HC1001</RequestID>
              <Host>hct-nw-client</Host>
              <Parameters>
                  <Param Name="RequestNumber">2</Param>
                  <Param Name="TimeOut">120</Param>
              </Parameters>        
        </Request> 
      </Requests>
</JBEToOverseerRequest>

Classes are:

#include<io.h>
#include<string>
#include<list>
#include<tinyxml.h>

using namespace std;

class Param
{ 
public:
	string value;
	string name;

	Param();

	Param( string value, string name)
	{ 
	  this->value=value;
	  this->name=name;
	}

};


class Parameters
{
public:
	list<Param> param;

	Parameters();
    Parameters(list<Param> param)
     {
	     this->param = param;
     }

};


class Request
{
public:
	string requestID;
	string host;
	Parameters parameters;

	Request();
	Request(string requestID, string host, Parameters parameters)
	{
		 this->requestID = requestID;
		 this->host = host;
		 this->parameters = parameters;
	}
};


class Requests
{
public:
	list<Request> requests;

	Requests();
	Requests(list<Request> requests)
	{ 
		this->requests = requests;
	}
};


class JBEToOverseerRequest
{
public:
	Parameters configParams;
	Requests requests;

	JBEToOverseerRequest();
	JBEToOverseerRequest(Parameters configparams, Requests requests)
	{
		this->configParams=configparams;
		this->requests=requests;
	}

	void save(const char* Filename);
};

class ConfigParams
{
public:
	Parameters configparams;

	ConfigParams();
	ConfigParams(Parameters configparams)
	{
		this->configparams = configparams;
	}
};

void JBEToOverseerRequest::save(const char* Filename)
{

	TiXmlDocument doc;  
	TiXmlElement* msg;
	
 	TiXmlDeclaration* decl = new TiXmlDeclaration( "1.0", "", "" );  
	doc.LinkEndChild( decl ); 
 
	TiXmlElement * root = new TiXmlElement("JBEToOverseerRequest");  
	doc.LinkEndChild( root );  

	//block configparams
	{
	TiXmlElement * configparams= new TiXmlElement( "ConfigParams" );  
    root->LinkEndChild( configparams ); 

    Param param1=Param("OverseerConfJBEPortNum", "1844");
	Param param2=Param("OverseerConfHctHostname" ," 10.30.89.117");
	Param param3=Param("OverseerConfTestExecParallelism", "5");
	Param param4=Param("OverseerConfServerName", "10.30.89.117");
	Param param5=Param("OverseerDirectory","NSR_TMP_DIRECTORY");
	Param param6=Param("OverseerTimeoutCleanup","yes");
	Param param7=Param("JBEcategory","HostConnectivity");
	Param param8=Param("JBECheckType","Extended");
	Param param9=Param("ReportRuns","4");
	Param param10=Param("ReportGrouping","RUNS");
	Param param11=Param("FilterType","N_RUNS");
	Param param12=Param("ExportDirPath","//diagnose");
	Param param13=Param("CancelInMillisec","0");

	 list<Param> params =list<Param>();
	 list <Param>::iterator Iter;

	 Iter=params.begin();
	 params.insert(Iter,param1);
	 params.insert(Iter,param2);
     params.insert(Iter,param3);
     params.insert(Iter,param4);
     params.insert(Iter,param5);
     params.insert(Iter,param6);
     params.insert(Iter,param7);
     params.insert(Iter,param8);
     params.insert(Iter,param9);
     params.insert(Iter,param10);
     params.insert(Iter,param11);
     params.insert(Iter,param12);
     params.insert(Iter,param13);

	 Parameters parameters=Parameters(params);

	 ConfigParams configparams=ConfigParams(parameters);
}

But i dont know how to encode these classes into XML form.
Can you help ? Urgently.
