今天继续学习Xerces序列化XML，保存到xml文件和打印。

class XmlSerializer

{

public:

~XmlSerializer();

voidAddNode(string nodeName,string nodeValue);

voidSave(string fileName);

voidPrint();

voidCreateDocument(string rootName);

}

catch (const XMLException& toCatch)

{

return 1;

}

XMLPlatformUtils::Terminate();

system("pause");
