        DOMNode* node = (DOMDocument*)doc->getDocumentElement();

        }
 
 
 
        theSerializer->release();
 
        //Writing to file try end
 
        return 0;
 
    }
 
 
 

and all I get as output is:

<?xml version="1.0" encoding="iso-8859-1"?><Config />


but the file looks like:

<?xml version="1.0" encoding="iso-8859-1"?>
<Config>
<Port nr="50000" />
<Data path="."/>
</Config>
 

What am I doing wrong?? Any idea??

Thanks in advance

I posted a link to your question in the C/C++ forum too.
