Well, in .H file I put:

#include "tinyxml/tinyxml.h"

class documentTinyNode : public TiXmlNode
{
public:
        documentTinyNode(); // CTOR object TiXmlNode
        ~documentTinyNode() { };

        LPCSTR GetAttribute( LPCSTR attributename ) { return ToElement
()->Attribute( attributename ); } // function class returns
attribute
        void SetAttribute( LPCSTR attributename, LPCSTR
attributevalue ) { ToElement()->SetAttribute( attributename,
attributevalue ); } // function class sets attribute

        documentTinyNode* Node( LPCSTR nodename, LPCSTR
attributenodename, LPCSTR attributetosearch ) // function class
returns new node
        {
                FirstChild(nodename);
                LPCSTR currentnodename = ToElement()->Attribute
(attributenodename);

                while ( (currentnodename != NULL) && (strcmp
(currentnodename, attributetosearch) != 0) ) {
                        IterateChildren(nodename , this);
                        currentnodename = ToElement()->Attribute
(attributenodename);
                }
                return ( (currentnodename != NULL) ? this : NULL );
        }
};

class documentTinyXML : public TiXmlDocument
{
public:
        documentTinyXML( LPCSTR xmlfilename ); // CTOR object
TiXmlDocument
        ~documentTinyXML() { };

        documentTinyNode* Node( LPCSTR nodename, LPCSTR
attributenodename, LPCSTR attributetosearch ) // function returns
object class TiXmlNode
        {
                documentTinyNode::Node(nodename, attributenodename,
attributetosearch);
        }); // function returns object class TiXmlNode
};

indeed in .CPP file I put:

documentTinyXML::documentTinyXML( LPCSTR xmlfilename )
{
        if (!LoadFile( xmlfilename ))
                AfxGetMainWnd()->MessageBox(_T("Error! Can't load xml
configuration file!\nIt could be not present or broken."), _T("MFC
Analyzer GUI"), MB_ICONSTOP | MB_OK);
}

void Ctest_tinyxmlDlg::OnBnClickedButton1()
{
        //<?xml version="1.0" ?>
        //<analyzer>
        // <module name="system-manager">
        // <sentence header="enableModules">
        // <row-info name="system-manager"
value="1" />
        // <row-info name="input-manager"
value="1" />
        // <row-info name="output-manager"
value="1" />
        // </sentence>
        // </module>
        // <module name="input-manager">
        // <sentence header="output-type">
        // <row-info name="out" value="1"
description="whatever-it-is" />
        // </sentence>
        // </module>
        // <module name="output-manager">
        // <sentence header="output-type">
        // <row-info name="out" value="1"
description="whatever-it-is" />
        // </sentence>
        // </module>
        //</analyzer>

        documentTinyXML* xmldocument = new documentTinyXML
( "example.xml" );
        LPCSTR pValue = xmldocument->Node("module","name","system-
manager")->Node("sentence","header","enableModules")->Node("row-
info","name","system-manager")->GetAttribute("value");
        GetDlgItem(IDC_EDIT1)->SetWindowText( (LPCTSTR)pValue );
}

As you can see I'd like to start from TiXmlDocument's type member
variable, getting deeper nodes to decide where to navigate since I
could have same sentences in different sublevels=85 how I could do
that?...

Thanks
