problem with loadXML("my_xml_string")

[getzel]

hi to all.
I'm loading an xml string into an IXMLDOMDocument via loadXML.
Why does it return to me the # -1.I'm assuming it means that it didn't load properly.

However ,I did it in a try/catch and it doesn't throw any _com_error exceptions,so obviously something else must be wrong.

Everything else involved in setting up the DOMDocument works.

Also when trying to get the root document I use the following code:

m_pDocRoot = pXMLDoc->documentElement;
pXMLDoc->get_documentElement(&m_pDocRoot);

if the DOMDocument would load correctly would that code be sufficient or does it need more??

Thanks
Getzel

-1 do mean that your document is incorrect.
After getting -1 exam yourDoc->parseError object.

if (yourDoc->loadXML( yourStr )==-1){
// You can use this for error message
  yourDoc->parseError.reason;
  yourDoc->parseError.errorCode;
  yourDoc->parseError.linepos;
  yourDoc->parseError.line;
  yourDoc->parseError.srcText;
  ...
}

To load a XML document from a XML formatted string i made the following function.
To get the root node i used the queryInterface since getNode did not return the root node but simply nothing.

	IXMLDOMDocument* pXmlDocTemp	= NULL;
  IXMLDOMNode*     pXmlNodeTemp = NULL;
	BSTR bstrXmlString;
	HRESULT hr = 0;

    // Create an empty XML document
	// ******************************************************************************		
  hr = CoCreateInstance(CLSID_DOMDocument, NULL, CLSCTX_INPROC_SERVER,
                        IID_IXMLDOMDocument, (void**)&pXmlDocTemp);
	if (hr == S_OK) {
		VARIANT_BOOL varIsOk;
    
		bstrXmlString = XMLHelperFunctions::asciiToBSTR(l_sParamRef.c_str());

		// Loading XML String into the XML Document
		// ******************************************************************************				
		hr = pXmlDocTemp->loadXML(bstrXmlString, &varIsOk);
		if ( hr == S_OK) {
		
			// so get a pointer to the IXMLDOMNode interface 
			// ******************************************************************************		
			hr =  pXmlDocTemp->QueryInterface(IID_IXMLDOMNode,(void**)&pXmlNodeTemp);
			if ( hr != S_OK) 
      {
				safeRelease(&pXmlDocTemp);
				safeRelease(&pXmlNodeTemp);
			}
		}
		else {
			safeRelease(&pXmlDocTemp);
		}
	}
	else {
		safeRelease(&pXmlDocTemp);
	}
	::SysFreeString(bstrXmlString);
	bstrXmlString = NULL;
