Hi,

you might try out www.scintilla.org[^] or the codemax [^] editor. Both very good text editors. The development for codemax has actually stopped but the source is still available i believe.

Both these projects too large. I need fast & small HTML viewer, not an editor... May be something else?

I'm having a problem adding a node to a XML file. I am able to open the file and read the elements but when i try to add a node is bombs.

MSXML::IXMLDOMElement * node;
node = document->createElement("Test");
document->appendChild(node);

It doesn't like the append to child. What is the correct way to add a new node in a XML docuement?

Thanks
Scott

try this instead:

<br />
MSXML::IXMLDOMElementPtr node;<br />
node = document->createElement("Test");<br />
document->appendChild(node);<br />

This way you will use the smart pointer classes that make querying and managing interfaces a lot simpler. You will also need to use the #inport statement to load teh MSXML library and provide thses smart pointers for you.

That's what you need.

Try the smart pointer implementation that I mentioned.

If that does not work then make sure that you have a valid document created.

no that bombs the same

Have you tried reading the error response codes to see why it bombs?

It would also be useful to see the code that you are using starting with where your Document is created.

Heres the code

String strPathName;
strPathName = "C:\\My Documents\\C_Projects\\XML\\books.xml";

CString csString;

HRESULT hr;
hr = CoInitialize(NULL);
if (FAILED(hr)) {
return;
}

hr = CoCreateInstance(MSXML::CLSID_DOMDocument, NULL,
CLSCTX_INPROC_SERVER | CLSCTX_LOCAL_SERVER,
MSXML::IID_IXMLDOMDocument, (LPVOID*)&document);
if (!document)
{
return;
}

BSTR bstr = NULL;
document->put_async(VARIANT_FALSE);
bstr = strPathName.AllocSysString();
VARIANT_BOOL varOkay = document->load(bstr);
SysFreeString(bstr);

BSTR nodeName;

if (varOkay)
{
hr = document->get_documentElement(&element);
if (FAILED(hr) || element == NULL)
{
MessageBox(_T("Empty document!"), _T("Error Loading XML"), MB_ICONWARNING);
return ;
}

element->get_nodeName(&nodeName);

m_List.AddString(CString(nodeName));

if(element->hasChildNodes())
{
MSXML::IXMLDOMNode* firstChild = NULL;
HRESULT hr;

hr = element->get_firstChild(&firstChild);
if (SUCCEEDED(hr) && firstChild != NULL)
{
((MSXML::IXMLDOMElement*)firstChild)->get_nodeName(&nodeName);

m_List.AddString(CString(nodeName));
}
}

MSXML::IXMLDOMElementPtr node;
node = document->createElement("Test");
document->appendChild(node);
}
else
{
long line, linePos;
BSTR reason = NULL;

document->get_parseError(&parseError);
parseError->get_errorCode(&hr);
parseError->get_line(&line);
parseError->get_linepos(&linePos);
parseError->get_reason(&reason);

CString strMsg;
strMsg.Format(_T("Error 0x%.8X on line %d, position %d\r\nReason: %s"),
hr, line, linePos, CString(reason));
MessageBox(strMsg, _T("Error Loading XML"), MB_ICONWARNING);

SysFreeString(reason);
return;
}

on the line -- document->appendChild(node);
is gives the error
Unhandled exception in XML.exe(kernal32.dll); 0xEO6D7363; Microsoft C++ Exception

Try appending your newly created node to the "element" or root nod eof your document rather than your document. I beleive your problem is that there is already a root element in the document and that is why there is a problem. However appending your new node ot the root element of the document seems to work fine.

If you have any other questions feel free to ask.

Good Luck
