Hi,

I'm evaluating Xtreme TookitPro and so far I'm quite happy with what I've try. I'm baffled by something though.

I need to read/write some dynamic content in XML, and what hoping to use for that CXTPPropExchangeXMLNode. But I can't figure how to traverse all nodes after a LoadFromFile !

If I know the node names, I understand I can do it with CXTPPropExchangeSection or GetEnumerator, but how if I don't know the names, and I need to traverse all the XML tree structure node after node and read their content ?

Couldn't find an example in the Sample files. Anyone care to point me in the right direction ?

Thanks for any help.

There are two ways,

1.Use CXTPPropExchangeEnumeratorPtr:

CXTPPropExchangeEnumeratorPtr pEnumerator(m_pSection->GetEnumerator(_T("*")));
pos = pEnumeratorMenu->GetPosition();
while (pos)
{
CXTPPropExchangeXMLNode* pNode = pEnumerator->GetNext(pos));

// ...
}

2.Use m_xmlSectionNode in CXTPPropExchangeXMLNode,

UINT CPropExchangeXMLNodeEx::GetNodesCount(LPCTSTR lpszSection)
{
if (m_xmlSectionNode == NULL)
{
return 0;
}

HRESULT hr;
UINT length;
IXMLDOMNodePtr xmlNodePtr;
IXMLDOMNodeListPtr xmlNodeListPtr;
hr = m_xmlSectionNode->selectNodes(_bstr_t(lpszSection ? lpszSection : _T("*")), (XTPXML::IXMLDOMNodeList**)&xmlNodeListPtr);

//...
}

Thanks for the help, now I understand. I was able to traverse the nodes with CXTPPropExchangeEnumeratorPtr, and retrieve each node name with xmlSectionNode::get_nodeName.

I find strange though that there is no simple interface within the CPropExchangeXMLNode class, and that one need first to derive the class to be able to access m_xmlSectionNode protected member, then to be forced to call the COM interface to get some details about the node, like its name. Some functions within CPropExchangeXMLNode class would have been useful. Or did I miss them ?

I see you have a CPropExchangeXMLNodeEx class, is that part of the XTreme Toolkit package ? Or is there something a little more elaborate planned in the Toolkit for working with XML files ?

Thanks again.

Hi,

You don't need to access CXTPPropExchangeXMLNode members.

Check this sample: http://forum.codejock.com/uploads/20060619_075701_PropExchangeSam.zip - PropExchangeSam.zip

Ah !
That is the sample I needed !

Now I understand better how to read the XML data.

Thanks Oleg.
