Update XML nodevalue with C++

I have an XML as below

<ROOT>
  <Device>
    <host>localhost</host>
    <Port>52000</Port>
  </Device>
  <DeviceHost>
    <Server>Server.exe</Server>
    <Port>81</Port>
  </DeviceHost>
  <Settings>
<Flag1>100</Flag1>
<Flag2>2000</Flag2>
  </Settings>
</ROOT>

How can I update the Flag1 and Flag2 to 200 and 4000 respectively without changing other values using VC++?

I have two function wrote using api MSXML.

 doc.LoadXml(Data);//for loading the xml data
 doc.Save(FilePath);//for saving the xml data

But my issue is before saving how can i update two node values

You would need to get the correct node by calling getElementsByTagName (which should return a NodeList containing one item) and then call put_nodeValue to write the value -- there are some MSDN samples here and here

EDIT: you should also be able to use doc.selectSingleNode("/ROOT/Flag1", &pNode) as per this MSDN article
