Problem with Parser & nsIHTMLContentSink

[Gil Fidel]

Hi,
I'm trying to parse a URL into an nsIDOMHTMLDocument. everything seems
to be going fine, but when I want to go over the resulting DOM
documenting, it turns out that it's empty (or contatins empty nodes) -
when I call routines such as GetTitle() or GetAnchors() they return
NS_OK as their return value, but the data they return is either a
blank string or an empty nsIHTMLCollection.

Does anyone has any idea what could be wrong with my code?

Thanks in advance.

the code:
//----------------------------------------------------------------------------
void PrintHTMLDOM(nsString * urlName)
{
    char * tmpStr = ToNewCString(*urlName);
    fprintf(stderr, "Start parsing %s\n", tmpStr);

    nsresult rv;
    // Create url
    nsIURI* url;
    
    nsCOMPtr<nsIIOService> service(do_GetService(kIOServiceCID, &rv));
    
    if (NS_FAILED(rv)) 
    {
        printf("Failed to create nsIIOService. error = [%x]\n", rv);
        return;
    }
    
    nsIURI *uri = nsnull;
    NS_ConvertUCS2toUTF8 uriStr(*urlName);
    rv = service->NewURI(uriStr, nsnull, nsnull, &uri);
    if (NS_FAILED(rv))
    
    {
        printf("Failed to create URI. error = [%x]\n", rv);
        return;
    }

    rv = uri->QueryInterface(NS_GET_IID(nsIURI), (void**)&url);
    NS_RELEASE(uri);
    if (NS_OK != rv) {
        printf("invalid URL: '");
        fputs(uriStr.get(), stderr);
        printf("'\n");
        return;
    }
    
    //Create input stream
    nsCOMPtr<nsIInputStream> inputStream;
    rv = NS_OpenURI(getter_AddRefs(inputStream), url);
    
    //Create webshell
    nsCOMPtr<nsIWebShell> webshell(do_GetService(kWebShellCID, &rv));
        
    //Create html document
    nsCOMPtr<nsIDocument> doc(do_CreateInstance(kHTMLDocumentCID,
&rv));
    if(NS_FAILED(rv))
    
    {
        fprintf(stderr, "Couldn't create an html document [%x]\n",
rv);
        return;
    }
    
    //Create parser
    nsCOMPtr<nsIParser> parser;

                                        (void **)&parser);
    if (NS_FAILED(rv))
    {
        fprintf(stderr, "Unable to create a parser : 0x%x\n", rv);
        return;
    }
    
    //Create htmlcontentsink
    nsCOMPtr<nsIHTMLContentSink> sink;
    parser->QueryInterface(kIHTMLContentSinkIID,
getter_AddRefs(sink));
                                        
    if(NS_FAILED(rv))
    {
        fprintf(stderr, "Unable to create an HTMLContentSink :
0x%x\n", rv);

    rv = parser->Parse(inputStream, NS_LITERAL_CSTRING("text/html") );
    if(NS_FAILED(rv))
    {
        fprintf(stderr, "Parsing failed : 0x%x\n", rv);
        return;
    }
    fprintf(stderr, "Finished parsing %s\nStart printing HTML DOM:\n",
tmpStr);
    
    nsCOMPtr<nsIDOMHTMLDocument> domdoc;
    rv = doc->QueryInterface(nsIDOMHTMLDocument::GetIID(),
    getter_AddRefs(domdoc));
    
    fprintf(stderr, "Parse_URL() - after nsIDOMHTMLDocument QI result

    nsString title;
    nsString URL;
    domdoc->GetTitle(title);
    domdoc->GetDomain(URL);
    fprintf(stderr, "Parse_URL() - Document title = %s\nID = %s\n",
ToNewUTF8String(title), ToNewUTF8String(URL));
    
    nsIDOMHTMLCollection * anchors

    PRUint32 len;
    links->GetLength(&len);
    fprintf(stderr, "GetAnchors from DOCUMENHT. anchors count = %d, rv
