XML/XSL

Im trying to create a XML document (using XMLDOM from  a C++ program) , but I cannot get the right structure when viewing the created document with a 'normal' text editor like notepad.exe
The document views in an explorer like this :
<TAG>
    <CHILDTAG>
            
    </CHILDTAG>
</TAG>

but in notepad.exe like this

<TAG><CHILDTAG></CHILDTAG></TAG>

My question is :
How can I create the XML file like this :

<TAG>\n\t<CHILDTAG>\n\t</CHILDTAG>\n</TAG>

with newline and tab characters BETWEEN the tags ?

Thank you ,
