how to parse xml for multiple specific node

C++

hey guys in my below code it checks for only 1 node whether that node is present or not. similarly i want to check the same for multiple specific node in same xml. so how do i do it.

reboot.xml

<rebootexclusiondata>
<memid>123</memid>
<siteid>123</siteid>
<regid>12345</regid>
<createdby>tanvi</createdby>
<updatedby>null</updatedby>
<exclusion>true</exclusion>
<dcdtime>2015-08-25 10:12:13</dcdtime>
<updcdtime>2015-08-25 10:12:13</updcdtime>
</rebootexclusiondata>

xmlparse.cpp:

void queryNodes()
{
	HRESULT hr = S_OK;
	IXMLDOMDocument *pXMLDom = NULL;
	IXMLDOMNodeList *pNodes = NULL;
	IXMLDOMNode *pNode = NULL;
	IXMLDOMNode *pNode1 = NULL;
	BSTR bstrQuery1 = NULL;
	BSTR bstrQuery2 = NULL;
	BSTR bstrNodeName = NULL;
	BSTR bstrNodeValue = NULL;
	VARIANT_BOOL varStatus;
	VARIANT varFileName;
	VariantInit(&varFileName);
	//<siteid>123</siteid>
	CHK_HR(CreateAndInitDOM(&pXMLDom));
	CHK_HR(VariantFromString(L"stocks.xml", varFileName));
	CHK_HR(pXMLDom->load(varFileName, &varStatus));
	if (varStatus != VARIANT_TRUE)
	{
		CHK_HR(ReportParseError(pXMLDom, "Failed to load DOM from stocks.xml."));
	}
	// Query a single node.
	//bstrQuery1 = SysAllocString(L"//rebootexclusiondata[2]/*");
	bstrQuery1 = SysAllocString(L"//rebootexclusiondata//exclusion//");
	
	CHK_ALLOC(bstrQuery1);
	CHK_HR(pXMLDom->selectSingleNode(bstrQuery1, &pNode));
	if (pNode)
	{
		printf("Result from selectSingleNode:\n");
		CHK_HR(pNode->get_nodeName(&bstrNodeName));
		CHK_HR(pNode->get_xml(&bstrNodeValue));
		SysFreeString(bstrNodeName);
		printf("Node, <%S>:\n", bstrNodeName);
		printf("\t%S\n%S\n", bstrNodeValue);
		if (0 == wcscmp(bstrNodeValue, L"<exclusion>true</exclusion>"))
		{
			printf("\n exe exit \n\n");
		}
		else
		{
			printf("\n go further! lets reboot the system\n\n");
		}
		SysFreeString(bstrNodeValue);
		SAFE_RELEASE(pNode);
	}

now in this code it checks whether

<siteid>123</siteid>

is present along with

<exclusion>true</exclusion>

or not
