No. The CVIXML API only supports element and attribute nodes. The lower-level MSXML instrument that is called by the CVIXML API supports all node types and can be used to read the XML comment. Note that you can get the ActiveX handles used by MSXML API from the CVIXML handles and can mix calls to both the APIs, or you can program entirely using the MSXML API to read the comment text. The following is some simple code to look for XML comment nodes in a CVIXML element.
static void ParseForXMLComment(CVIXMLElement element)
{
int i, nChildren;
MSXMLObj_IXMLDOMElement handle = 0;
MSXMLObj_IXMLDOMNodeList childList = 0;
MSXMLObj_IXMLDOMNode child = 0;
CVIXMLGetElementActiveXHandle(element, &handle);
MSXML_IXMLDOMElementGetchildNodes(handle, 0, &childList);
MSXML_IXMLDOMNodeListGetlength(childList, 0, &nChildren);
for (i = 0; i < nChildren; ++i)
{
MSXMLType_DOMNodeType type;
MSXML_IXMLDOMNodeListGetitem(childList, 0, i, &child);
MSXML_IXMLDOMNodeGetnodeType(child, 0, &type);
if (type == MSXMLConst_NODE_COMMENT)
{
char * comment = 0;
MSXML_IXMLDOMCommentGettext(child, 0, &comment);
DebugPrintf("Comment: %s\n", comment);
CA_FreeMemory(comment);
}
CA_DiscardObjHandle(child);
child = 0;
}
CA_DiscardObjHandle(child);
CA_DiscardObjHandle(childList);
CA_DiscardObjHandle(handle);
}
