写XML文件：

 1 var
 2   IXMLDoc : IXMLDocument;
 3   XMLNode, xNodeItem: IXMLNode;
 4 begin
 5   IXMLDoc := NewXMLDocument();
 6   try
 7     XMLNode := IXMLDoc.AddChild(‘ConfigInfo‘);
 8 
 9     xNodeItem := XMLNode.AddChild(‘VideoDB‘);
10     xNodeItem.Attributes[‘Host‘] := VideoSQLConfig.strAddress;
11     xNodeItem.Attributes[‘UserName‘] := VideoSQLConfig.strUserName;
12     xNodeItem.Attributes[‘PassWord‘] := VideoSQLConfig.strPassWord;
13     xNodeItem.Attributes[‘DBName‘] := VideoSQLConfig.strDBName;
14       
15 
16     IXMLDoc.SaveToFile(strFileName);
17   finally
18     IXMLDoc := nil;
19   end;
20 end;
